Abstract:
Abstract For decades, reliability has been the watchword for electric utilities, but now there’s a focus on a related concept: Resilience. It has gained notice as planners began thinking about increased natural disasters brought on by climate change, man-made interference due to malicious cyberattacks, and the instability brought about by adding large quantities of renewable energy. Resilience has become a legitimate field of study involving industry, academia, and government labs, complete with experts in the field. This article delves deeper into the need to achieve electrical grid resiliency as intensity of natural disaster amplifies.

Abstract:
Energy communities and their resiliency are both relatively new subjects of interest that need deeper analysis. The concepts are emerging in the current trend of energy decarbonization, combined with unpredictable external factors, such as extreme weather, or nearby conflicts, such as wars. To be resilient against electrical network supply outages or heavy blackouts, energy communities need appropriate design of their electrical microgrids to maintain an acceptable level of activity in both normal and critical situations. The paper deals with aspects of the design of the electrical network used by energy communities, seen as microgrids designed to offer an acceptable level of safe operation and energy resilience. While electrical network resilience covers both the public network (main grid) and local microgrid of an energy community, the paper focuses on the safe operation and resilience related to the local microgrid as a distinct goal from the one of preserving the main grid’s functionality. The first section considers definitions of energy resilience and some of the existing preoccupations on the subject. A second section of the paper presents different aspects of the design of a microgrid, with the purpose of increasing its safety in operation and energy community resilience. The section addresses electrical network architectures, multiple roles of storage resources related to prosumers and to islanded microgrids with high-RES penetration, and other aspects such as the impact of electrification of heating through, e.g., heat pumps. The next sections present selected use cases, which develop some of these design aspects by using typical real data for the analysis and assessing solutions to address resilient microgrid challenges. The selected use cases consider simplified approaches for real-time and short-term storage needs and operational use in microgrids, maintaining voltage levels in a high-RES scenario by using battery P control, and optimization of storage resources to cope with the needs. Conclusions are given in a final section, which also presents future work for a presumed continuation with other use cases related to storage means, safe operation, and resilient design of energy communities microgrids.

Abstract:
The stigmatization of PLWHA persists, causing it difficult for PLWHA to participate in social activities. Due to prejudice, intimidation, and neglect, self-exploration is inhibited for HIV-positive individuals, particularly adolescents. As PLWHA, adolescents must be able to learn and develop their resilience to survive in challenging conditions and times. Therefore, this study aims to determine the resilience profile of adolescents affected with HIV/AIDS in Salatiga City. The methodology employed is qualitative and phenomenologically descriptive. The participants were two adolescents in their late 20s who were infected with the HIV/AIDS virus and resided in Salatiga City. Interviews, observations, and data triangulation were used to collect information. The results indicated that the resilience of PLWHA adolescents was correlated with their capacity to respond to problems healthily and effectively. The resilience-building processes of the two PLWHA adolescents share similarities. This was evident from the two PLWHA adolescents' emotional regulation, impulse control, optimism, problem-solving skills, empathy, self-efficacy, and accomplishment. In addition to elements, the two PLWHA adolescents experienced a variety of characteristics that affect resilience, including spirituality, self-esteem, and social support. Despite specific disparities in creating resilience, it is evident that the two adolescents living with HIV are already resilient since they can adjust to their conditions as PLWHA and continue to live productive lives as late adolescents. Abstrak: Stigmatisasi pada ODHA masih terus terjadi, sehingga sering kali individu ODHA merasa sulit untuk hidup di tengah kehidupan sosial. Individu ODHA khususnya remaja juga mengalami problematika mental yang sengat berat ketika ada dalam lingkungan sosial, sehingga eksplorasi diri menjadi terhambat karena adanya dikriminasi, intimidasi, dan pengabaian. Sebagai ODHA, individu remaja harus bisa belajar dan membentuk sarana diri berupa kemampuan resilien, agar dapat bertahan di situasi dan masa-masa sulit. Maka dari itu, penelitian ini bertujuan untuk mengetahui dan mengidentifikasi secara mendalam mengenai gambaran resiliensi pada remaja yang terjangkit virus HIV/AIDS di Kota Salatiga. Pendekatan yang digunakan adalah kualitatif dengan desain deskriptif fenomenologi. Partisipan yang terlibat sebanyak 2 remaja akhir usia 20 tahun yang terjangkit virus HIV/AIDS dan tinggal di Kota Salatiga, dengan menggunakan teknik purposive sampling. Pengumpulan data melalui wawancara, observasi, dan triangulasi data. Hasil penelitian menunjukkan bahwa resiliensi remaja ODHA berhubungan dengan bagaimana mereka dapat merespon setiap permasalahan secara sehat dan produktif. Kedua remaja ODHA memiliki kemiripan dalam proses pembentukan resiliensi. Hal ini tampak dari bagaimana kedua remaja ODHA dapat memenuhi aspek regulasi emosi, pengendalian impuls, optimisme, kemampuan menganalisis masalah, empati, efikasi diri, dan pencapaian. Selain aspek, kedua remaja ODHA juga mengalami berbagai faktor yang membentuk resiliensi, yaitu spiritualitas, harga diri, dan dukungan sosial. Meskipun terdapat beberapa perbedaan dalam proses pembentukan resiliensi, secara keseluruhan dapat dilihat bahwa kedua remaja ODHA sudah resilien karena dapat beradaptasi dengan kondisi mereka sebagai ODHA serta tetap produktif menjalani hidup mereka sebagai individu remaja akhir.

Abstract:
One of the main objectives of new operating regimes, such as transactional power systems, is to make the power grid more resilient to catastrophes and disturbances, while at the same time making it possible to supply electricity to the largest number of customers. Although this is true, it is well known among power system operators that not all customers are the same. The consequence of this is that any discussion around the impact of transactional power systems on power system resilience should consider the needs of its critical users (such as control centers, fire stations, and hospitals) over other users. In assessing power system resilience, a metric is needed that gives “bonus points” to those systems that, under all circumstances, can continue to provide electricity to their critical users. In order to serve as a parameter in the assessment of power grid resilience, the research presented here discusses the proportion of critical loads existing in critical infrastructures. Once the critical loads are characterized, the next step is the inclusion of these loads in resilience metrics. This paper proposes resiliency metrics in which certain customers (those categorized as critical) are assigned a higher weight than others. One thing to keep in mind is the fact that there is no one-size-fits-all approach for all power systems, and that the assignment of such weights to customers can vary significantly from one operator to another based on their unique systems and the current and expected states of their critical customers.

Abstract:
The economic and resilient operation of power systems has always been one of the main priorities of energy systems. In spite of improvements in various fields of energy systems, especially power systems, the issue of resilience has become more important. For this purpose, this paper proposes a multiobjective optimization model to improve the economic performance of energy hub systems and improve the resilience of electrical consumers. Also, consumer welfare, which is a function of the energy not supplied index, is maximized over a 24-hour period by considering extreme weather conditions. The ε-constraint method is applied to solve the proposed model by transforming the multiobjective optimization problem into several single-objective optimization problems. The max-min fuzzy method is also used to select the optimal solution among the Pareto solutions. A sample hub system is made up of electrical, thermal, and gas loads, electrical and thermal energy sources, and storage systems employed as a test system. A group of actions is applied to improve the resilience of the system, which may be affected by outages caused by storms under the resilience response program (RRP). The results proved the efficiency of the proposed RRP in improving economics and resilience.

Abstract:
Extreme weather events lead to electrical network failures, damages, and long-lasting blackouts. Therefore, enhancement of the resiliency of electrical systems during emergency situations is essential. By using the concept of standby redundancy, this paper proposes two different energy systems for increasing load resiliency during a random blackout. The main contribution of this paper is the techno-economic and environmental comparison of two different resilient energy systems. The first energy system utilizes a typical traditional generator (TG) as a standby component for providing electricity during the blackouts and the second energy system is a grid-connected microgrid consisting of photovoltaic (PV) and battery energy storage (BES) as a standby component. Sensitivity analyses are conducted to investigate the survivability of both energy systems during the blackouts. The objective function minimizes total net present cost (NPC) and cost of energy (COE) by considering the defined constraints of the system for increasing the resiliency. Simulations are performed by HOMER, and results show that for having almost the same resilience enhancement in both systems, the second system, which is a grid-connected microgrid, indicates lower NPC and COE compared to the first system. More comparison details are shown in this paper to highlight the effectiveness and weakness of each resilient energy system.

Abstract:
Fundamental shifts in the structure and generation profile of electrical grids are occurring amidst increased demand for resilience. These two simultaneous trends create the need for new planning and operational practices for modern grids that account for the compounding uncertainties inherent in both resilience assessment and increasing contribution of variable inverter-based renewable energy sources. This work reviews the research work addressing the changing generation profile, state-of-the-art practices to address resilience, and research works at the intersection of these two topics in regards to electrical grids. The contribution of this work is to highlight the ongoing research in power system resilience and integration of variable inverter-based renewable energy sources in electrical grids, and to identify areas of current and further study at this intersection. Areas of research identified at this intersection include cyber-physical analysis of solar, wind, and distributed energy resources, microgrids, network evolution and observability, substation automation and self-healing, and probabilistic planning and operation methods.

Abstract:
In the developing countries, social services for people with disability (PwD) are still limited and responsibility for the development of chil- dren with disability is often associated with their parent/s. The children with special needs, including those with autism, impacts all members of his/her family and leads to the emergence of crisis experiences in the family. The article talks the resiliency of parent/s with autistic chil- dren in Palembang Terapi Center. This paper is written with a phenom- enological approach. Findings show that dominant themes emerged regarding resiliency in this paper setting are self-acceptance, self-ef- ficacy, and adaptation. Several factors that influence the resilience of parents with autistic children are individual abilities, children’s con- ditions, environment, and religious values. Moreover, there are three types of resiliencies according to the level of difficulty experienced by parent/s; high level of difficulty, moderate level of difficulty, and lower level of difficulty. Di negara berkembang, keterbatasan layanan sosial bagi penyandang disabilitas dan tanggung jawab atas tumbuh kembang anak penyandang disabilitas seringkali dikaitkan dengan orang tua. Keberadaan anak berkebutuhan khusus, termasuk anak dengan autisme berdampak pada seluruh anggota keluarga dan berujung pada kemuncul pengalaman krisis keluarga. Artikel ini mengeksplorasi resiliensi orang tua yang memiliki anak dengan autisme di Pusat Terapi Palembang. Artikel ini ditulis dengan pendekatan fenomenologis. Temuan menunjukkan tema terkait resiliensi dalam penerimaan diri, efikasi diri, dan adaptasi. Temuan lain adalah faktor yang mempengaruhi resiliensi orang tua yang memiliki anak autisme dengan kemampuan individu, kondisi anak, lingkungan, dan nilai agama. Selain itu, ada tiga jenis resiliensi menurut tingkat kesulitan yang dialami orang tua; tingkat kesulitan tinggi, sedang, dan rendah.

Abstract:
The COVID-19 pandemic represents a massive, often unanticipated, external disruption for many companies. As a concept for responding to such disruption, organizational resilience has recently received great attention. In the organizational context, the overriding question is how companies can become more resilient. This study aims to contribute to answering this question by identifying, categorizing, and providing specific business model patterns for achieving resilience on the corporate level. For this purpose, a review of publications by major consulting firms was conducted. Patterns were extracted from publications until a convergence criterion indicated that no new pattern could be identified considering further publications. The 110 extracted unique patterns were clustered into 13 objectives, and additionally categorized according to resilience phases, as well as business model elements, to support the application in practice. The final catalog of patterns was validated through expert interviews and thus provides organizations, such as those in the electrical industry, with an overview and specific approaches on how to tackle industrial resilience through the adaption of their business model.

This thesis focuses on the analysis of robustness in large interconnected networks. Many real life systems in transportation, economics, finance and social sciences can be represented as networks. The individual constituents, or nodes, of the network may represent vehicles in the case of vehicular platoons, production sectors in the case of economic networks, banks in the case of financial sector, or people in the case of social networks. Due to interconnections between constituents in these networks, a disturbance to any one of the constituents of the network may propagate to other nodes of the network. In any stable network, an incident noise, or disturbance, to any node of the network eventually fades away. However, in most real life situations, the object of interest is a finite time analysis of individual node behavior in response to input shocks, or noise, i.e., how the effect of an incident disturbance fades away with time. Such transient behavior depends heavily on the interconnections between the nodes of the network. In this thesis we build a framework to assess the transient behavior of large interconnected networks. Based on this formulation, we categorize each network into one of two broad classes - resilient or fragile. Intuitively, a network is resilient if the transient trajectory of every node of the network remains sufficiently close to the equilibrium, even as the network dimension grows. This is different from standard notion of stability wherein the trajectory excursion may grow arbitrarily with the network size. In order to quantify these transient excursions, we introduce a new notion of resilience that explicitly captures the effect of network interconnections on the resilience properties of the network. We further show that the framework presented here generalizes notions of robustness studied in many other applications, e.g., economic input-output production networks, vehicular platoons and consensus networks. The main contribution of this thesis is that it builds a general framework to study resilience in arbitrary networks, thus aiding in more robust network design.

Abstract:
The Internet is a fundamental infrastructure in modern life, supporting many different communication services. One of the most critical properties of the Internet is its ability to recover from failures, such as link or equipment failure. The goal of network resilience heavily influenced the design of the Internet, leading to the use of distributed routing protocols. While distributed algorithms largely solve the issue of network resilience, other concerns remain. A significant concern is network management, as it is a complex and error-prone process. In addition, network control logic is tightly integrated into the forwarding devices, making it difficult to upgrade the logic to introduce new features. Finally, the lack of a common control platform requires new network functions to provide their own solutions to common, but challenging, issues related to operating in a distributed environment. A new network architecture, software-defined networking (SDN), aims to alleviate many of these network challenges by introducing useful abstractions into the control plane. In an SDN architecture, control functions are implemented as network applications, and run in a logically centralized network operating system (NOS). The NOS provides the applications with abstractions for common functions, such as network discovery, installation of forwarding behaviour, and state distribution. Network management can be handled programmatically instead of manually, and new features can be introduced by simply updating or adding a control application in the NOS. Given proper design, an SDN architecture could improve the performance of reactive approaches to restoring traffic after a network failure. However, it has been shown in this dissertation that a reactive approach to traffic restoration will not meet the requirements of carrier grade networks, which require that traffic is redirected onto a back-up route less than 50 ms after the failure is detected. To achieve 50 ms recovery, a proactive approach must be used, where back-up rules are calculated and installed before a failure occurs. Several different protocols implement this proactive approach in traditional networks, and some work has also been done in the SDN space. However, current SDN solutions for fast recovery are not necessarily suitable for a carrier grade environment. This dissertation proposes a new failure recovery strategy for SDN, based on existing protocols used in traditional carrier grade networks. The use of segment routing allows for back-up routes to be encoded into the packet header when a failure occurs, without needing to inform other switches of the failure. Back-up routes follow the post-convergence path, meaning that they will not violate traffic engineering constraints on the network. An MPLS (multiprotocol label switching) data plane is used to ensure compatibility with current carrier networks, as MPLS is currently a common protocol in carrier networks. The proposed solution was implemented as a network application, on top of an open-source network operating system. A geographically distributed network testbed was used to verify the suitability for a geographically distributed carrier network. Proof of concept tests showed that the proposed solution provides complete protection for any single link, link aggregate or node failure in the network. In addition, communication latencies in the network do not influence the restoration time, as they do in reactive approaches. Finally, analysis of the back-up path metrics, such as back-up path lengths and number of labels required, showed that the application installed efficient back-up paths.

General Adverserial Networks (GANs) provide a useful approach to new data generation with a few common problems of mode collapsing and oscillating behavior. Lipizzaner improves the performance of distributed GAN training with the use of a spatially distributed coevolutionary algorithm and gradient-based optimizers. However, in its current state the use of Lipizzaner is limited by its vulnerabilities on systems that encounter frequent node failures. When faced with a single node failure, Lipizzaner's entire experiment comes to a halt and must be restarted. We see a need for increasing Lipizzaner's resilience to such failures and do the following. We apply a combination of uncoordinated checkpointing, attempted reconnecting, and restarting nodes to form a simple and efficient solution for system resilience in Lipizzaner. We find that checkpointing and reconnecting are essential and simple solutions to failure recovery in Lipizzaner, while restarting nodes requires a more nuanced approach that shows promising results when used correctly to address node failures.

Abstract:
Cloud infrastructure services are enabling organizations and enterprises to outsource a wide range of computing, storage, and networking needs to external service providers. These offerings make extensive use of underlying network virtualization, i.e., virtual network (VN) embedding, techniques to provision and interconnect customized storage/computing resource pools across large network substrates. However, as cloud-based services continue to gain traction, there is a growing need to address a range of resiliency concerns, particularly with regards to large-scale outages. These conditions can be triggered by events such as natural disasters, malicious man-made attacks, and even cascading power failures. Overall, a wide range of studies have looked at network virtualization survivability, with most efforts focusing on pre-fault protection strategies to set aside backup datacenter and network bandwidth resources. These contributions include single node/link failure schemes as well as recent studies on correlated multi-failure \disaster" recovery schemes. However, pre-fault provisioning is very resource-intensive and imposes high costs for clients. Moreover this approach cannot guarantee recovery under generalized multi-failure conditions. Although post-fault restoration (remapping) schemes have also been studied, the effectiveness of these methods is constrained by the scale of infrastructure damage. As a result there is a pressing need to investigate longer-term post-fault infrastructure repair strategies to minimize VN service disruption. However this is a largely unexplored area and requires specialized consideration as damaged infrastructures will likely be repaired in a time-staged, incremental manner, i.e., progressive recovery. Furthermore, more specialized multicast VN (MVN) services are also being used to support a range of content distribution and real-time streaming needs over cloud-based infrastructures. In general, these one-to-many services impose more challenging requirements in terms of geographic coverage, delay, delay variation, and reliability. Now some recent studies have looked at MVN embedding and survivability design. In particular, the latter contributions cover both pre-fault protection and post-fault restoration methods, and also include some multi-failure recovery techniques. Nevertheless, there are no known efforts that incorporate risk vulnerabilities into the MVN embedding process. Indeed, there is a strong need to develop such methods in order to reduce the impact of large-scale outages, and this remains an open topic area. In light of the above, this dissertation develops some novel solutions to further improve the resiliency of the network virtualization services in the presence of large outages. Foremost, new multi-stage (progressive) infrastructure repair strategies are proposed to improve the post-fault recovery of VN services. These contributions include advanced simulated annealing metaheuristics as well as more scalable polynomial-time heuristic algorithms. Furthermore, enhanced \risk-aware" mapping solutions are also developed to achieve more reliable multicast (MVN) embedding, providing a further basis to develop more specialized repair strategies in the future. The performance of these various solutions is also evaluated extensively using custom-developed simulation models.

Abstract:
Today, there is a growing number of buildings in a neighborhood and business parks that are utilizing renewable energy generation, to reduce their electric bill and carbon footprint. The most current way of implementing a renewable energy generation is to use solar panels or a windmill to generate power; then use a charge controller connected to a battery bank to store power. Once stored, the user can then access a clean source of power from these batteries instead of the main power grid. This type of power structure is utilizing a single module system in respect of one building. As the industry of renewable power generation continues to increase, we start to see a new way of implementing the infrastructure of the power system. Instead of having just individual buildings generating power, storing power, using power, and selling power there is a fifth step that can be added, sharing power. The idea of multiple buildings connected to each other to share power has been named a microgrid by the power community. With this ability to share power in a microgrid system, a catastrophic event which cause shutdowns of power production can be better managed. This paper then discusses the data from simulations and a built physical model of a resilient microgrid utilizing these principles.

Abstract:
The growing market of portable devices and smart wearables has contributed to innovation and development of systems with longer battery-life. While Near Threshold Computing (NTC) systems address the need for longer battery-life, they have certain limitations. NTC systems are prone to be significantly affected by variations in the fabrication process, commonly called process variation (PV). This dissertation explores an intriguing effect of PV, called choke points. Choke points are especially important due to their multifarious influence on the functional correctness of an NTC system. This work shows why novel research is required in this direction and proposes two techniques to resolve the problems created by choke points, while maintaining the reduced power needs.

Abstract:
This study investigates the Internet's resilience to instabilities caused by the mismatch of its topological state and routing information. A first numerical analysis proves that the Internet possesses unused path diversity which could be employed to strengthen its resilience to failures. Therefore, a new routing framework called Chain Routing, which takes advantage of such path diversity, is proposed. This novel idea is based in the mathematical concept of complete order, which is a binary relation that is irreflexive, asymmetric, transitive and complete. More important is the fact that complete orders, when represented as a graph, are the most connected digraph that does not contain any cycles. Consequently, a complete order could be applied to route information from a source to a destination with the guarantee that cycles will not develop in a path. A second numerical analysis demonstrates the feasibility of implementing Chain Routing as part of a routing protocol. Finally, an analysis is presented on how network stability could be maintained if a routing protocol integrates complete orders in time and topology.

Abstract:

The resource mix for the U.S. electrical power grid is undergoing rapid change with increased levels of solar photovoltaic (PV) and wind turbine electricity generating capacity. There are potential negative impacts to grid resilience resulting from hurricane damage to wind and solar power stations connected to the power transmission grid. Renewable power sources are exposed to the environment more so than traditional thermal power sources. To our knowledge, damage to power generating stations is not included in studies on hurricane damage to the electrical power grid in the literature. The lack of a hurricane wind damage prediction model for power stations will cause underestimation of predicted hurricane wind damage to the electrical grid with high percentages of total power generation capacity provided by solar photovoltaic and wind turbine power stations.

Modeling hurricane wind damage to the transmission grid and power stations can predict damage to electrical grid components including power stations, the resultant loss in power generation capacity, and restoration costs for the grid. This Praxis developed models for hurricane exposure, fragility curve-based damage to electrical transmission grid components and power generating stations, and restoration cost to predict resiliency factors including power generation capacity lost and the restoration cost for electrical transmission grid and power generation system damages. Synthetic grid data were used to model the Energy Reliability Council of Texas (ERCOT) electrical grid. A case study was developed based on Hurricane Harvey. This work is extended to evaluate the changes to resiliency as the percentage of renewable sources is increased from 2017 levels to levels corresponding to the National Renewable Energy Lab (NREL) Futures Study 2050 Texas scenarios for 50% and 80% renewable energy.

Everything from disaster response coordination, communication, public lighting and safety, as well as the provision of health services, basic household operations and the economic recovery of the community, relies on electricity to function. This dependency, coupled with the vulnerability of our electricity networks, highlights the need to establish resilient distribution networks. The notion that small-scale solar PV (SSPV) and battery energy storage systems (BESS) might contribute to network resilience, has become a popular avenue of investigation, with the growing uptake of these technologies. Beyond the technical challenges of establishing a smart grid network and reaching the required uptake of the technology to have sufficient storage capacity, a third factor relating to householders’ willingness to share stored energy with their community, remains largely unexplored. In a marked departure from the existing literature, this thesis investigates the use of SSPV and BESS for distribution network resilience and the community’s attitudes towards sharing energy resources. The research focusses, not on the technical and regulatory aspects of network resilience which are favoured by researchers’, but the behavioural component founded in social sciences. A model for network resilience utilising SSPV and BESS is presented, which argues that a key component of resilience in the aftermath of a disaster event, hinges on the community’s commitment to conservation of energy resources and their willingness to share their stored reserves for the common good. This research investigates the community’s perspectives on this resilience approach, by exploring attitudinal and behavioural aspects associated with helping the community, to determine the viability of pursuing SSPV and BESS as a practical network resilience option.

Abstract:
Hurricanes are one of the main causes for blackouts and related infrastructure damage in the United States. Electrical transmission towers, which are key parts of the electrical transmission networks, are vulnerable to high wind speeds during storms. Collapse of transmission towers may lead to a loss of functionality of transmission lines. This research focuses on regional analysis of electrical transmission networks under hurricane hazards through developing beam elements for analyzing transmission towers, selection of hurricane wind records that incorporate uncertainty quantification, generating collapse fragility curves for transmission towers, and regional damage assessment of transmission networks.

Abstract:
This research utilizes Bayesian network to address a range of possible risks to the electrical power system and its interdependent networks (EIN) and offers possible options to mitigate the consequences of a disruption. The interdependent electrical infrastructure system in Washington, D.C. is used as a case study to quantify the resilience using the Bayesian network. Quantification of resilience is further analyzed based on different types of analysis such as forward propagation, backward propagation, sensitivity analysis, and information theory. The general insight drawn from these analyses indicate that reliability, backup power source, and resource restoration are the prime factors contributed towards enhancing the resilience of an interdependent electrical infrastructure system.

Abstract:
Electrical energy storage (EES) has emerged as a key enabler for access to electricity in remote environments and in those environments where other external factors challenge access to reliable electricity. In cold climates, energy storage technologies face challenging conditions that can inhibit their performance and utility to provide electricity. Use of available energy storage technologies has the potential to improve Army installation resilience by providing more consistent and reliable power to critical infrastructure and, potentially, to broader infrastructure and operations. Sustainable power, whether for long durations under normal operating conditions or for enhancing operational resilience, improves an installation’s ability to maintain continuity of operations for both on- and off-installation missions. Therefore, this work assesses the maturity of energy storage technologies to provide energy stability for Army installations in cold regions, especially to meet critical power demands. The information summarized in this technical report provides a reference for considering various energy storage technologies to support specific applications at Army installations, especially those installations in cold regions.
