Abstract:
The existing centralized power supply system has the alternative due to distributed generation. By certain conditions distributed cogeneration allows to increase the reliability and quality of power supply and to reduce the cost of electricity for consumers. Therefore, a lot of energy-intensive consumers switched to their own power supply systems, as it turned out to be a competitive technical solution. The total gasification of the country’s regions and the presence of domestic manufacturers of gas turbine and gas piston power plants accelerated this process. Nowadays local power systems are emerging with cogeneration plants are the main source of heat and electricity there. The feasibility justification of the kind and type of generation is determined by many factors, including circuit-mode parameters in the local power system and adjacent network. Local power systems based on the principles of self-balance are proposed to name as energy cells. The integration of energy cells with regional power system increases the technical and economic effectiveness of power supply system for consumers. The proposed power systems transition leads to certain systemic effects. Received effects are depending on functions of distributed generation. This paper explores the impact of scheme and mode factor on the technical effects.

Abstract:
A method is presented for justifying the construction of a mathematical model of the process of supplying consumers from local sources, taking into account deterministic input information. The target function of the mathematical model is to minimize financial investments in the construction and operation of the local energy supply system using renewable energy sources. Presented activities are aimed at assessing the efficiency of use of fuel and energy resources by local power supply systems, determining the conditions for a positive economic effect, substantiating the composition and main technical parameters of power plants and devices of the local power supply system. At the same time, the conditions of competitiveness of the local power supply system relative to the centralized one should be observed. Sources of local power supply systems should be built on the basis of biogas plants that are capable of producing biogas with long-term storage in gas storages and at the same time are energy storage batteries for other renewable sources. The presented analysis of the energy balance of a biogas plant, taking into account the synergistic effects of interaction between centralized and local energy systems, will make it possible to make optimal decisions for creating a bioenergy complex.

Abstract:
Urgency of the research. Current trends of distributed generation development in Ukraine indicate a rapid generation in-crease from renewable energy plants. Most developed countries gradually refuse from the fossil fuels use and invest more and more to the “green” energy. Therefore, there is a need for a detailed study of the operation conditions of distributed energy sources due to their instability, as well as the processes that arise in distribution electric networks with diverse types of distributed energy sources. Target setting. In the producing process of power energy by distributed energy sources due to the increase in their num-ber, there are situations where several renewable sources of energy operate to only one system of buses. Thus, such distributive networks acquire the features of a local power system, which complicates the control process of such systems, and also there is a problem with the electricity supply of consumers. Actual scientific researches and issues analysis. The analysis of publications suggests that in literature more attention is paid to studying the operating modes of solar power plants, or small hydroelectric power plants. However, almost no attention was paid to the study of their cooperation work. Uninvestigated parts of general matters defining. Only a few works are devoted to the study of the cooperation of the diverce sources of distributed energy sources in the local electrical systems. That is why, their impact on power distribution networks and on the grid in general has not been studied extensively. The research objective. In this article was considered the influence of asynchronous generators on small hydroelectric power plants on the operation modes of distribution electrical networks, and were investigated the processes that are occurring in local power systems with different types of distributed energy sources. The statement of basic materials. Based on the research results, was developed a computer model of a such system in the PS CAD software environment. Two solar stations and one small hydroelectric power station with an asynchronous generator were connected to the power supply. It was shown the simulation of two modes of operation: a joint operation of a small hydroelectric power station, two solar power stations and a power supply center; a joint operation of a small hydroelectric pow-er plant, two solar power stations and a power supply disconnected. Conclusions. As a result of computer simulation, it is shown that by switching on a small hydroelectric power plant with an asynchronous generator in the case of an emergency shutdown of centralized power supply, it is possible to restore the work of solar power plants, and thus partially or completely restore the power supply of consumers.

Abstract:
The energy sector of Russia is transforming, followed by total electrification and gasification, which has radically changed the fuel landscape and allowed enterprises in various sectors of the economy to create their energy sources based on gas turbine and gas piston cogeneration plants. There are more and more balanced local intelligent energy systems for various purposes, more often operating autonomously, since the process of their integration with the unified energy system of Russia is impossible without power and energy output, which is contrary to the interests of generating companies, territorial grid organizations and the system operator. Overcoming the administrative and technological barriers and obstacles created by significant players in the electric power industry reduces the technical and economic efficiency of local intelligent energy systems that can bring considerable beneficial systemic effects.THE PURPOSE Substantiation of the obtained system effects from integrating local intelligent energy systems.METHODS. A systematic approach to identify the effects of the integration of local intelligent energy systems with the unified energy system of Russia.RESULTS. Local intelligent energy systems are considered objects of distributed electric power industry that perform certain system functions, which is accompanied by a change in the properties of reliability, efficiency and environmental friendliness of the production and transmission of heat and electricity, which leads to various effects. The presence and size of the effects are determined by the type and type of the local intelligent energy system. It is shown that the integration of communal local intelligent energy systems, created for the energy supply of the population and equivalent consumers, has a certain advantage.CONCLUSION. The integration of communal local intelligent energy systems makes it possible to increase the availability and uninterrupted power supply, reduce the negative impact of off-market surcharges and cross-subsidization, improve the uniformity of load schedules for generating and grid equipment, which increases the efficiency of the unified energy system of Russia.

Abstract:
PurposeThe purpose of this paper is to investigate supply chain relationships in an urban local fresh food system from a retailer perspective to examine the types of relationships and the factors underpinning the development of such relationships.Design/methodology/approachUsing the multiple case study method, interview data from twelve urban local fresh food retailers in Sydney were analysed using the thematic analysis.FindingsThis study finds that balanced power relationships in the supply chain allow reasonable power to sit with growers in product price determination irrespective of the dependency of small-scale growers on relatively large local retailers. Trust-based relationships are developed over multiple transactions, where shared values across the supply chain and consistently low opportunistic behaviour in reward sharing are demonstrated to be the crucial factors underpinning close relationships. This study also found evidence of horizontal supply chain linkages among retailers in a competitive environment.Practical implicationsFindings of this study have implications for policymakers in designing urban fresh food systems and for practitioners in large urban retailers including supermarkets that attempt to integrate local food into their product portfolio.Originality/valueThis study extends the local food system literature dominated by rural studies to include new knowledge about the dynamics of collaborations in contemporary urban local fresh food supply chains. It provides the first empirical evidence of lateral inventory transshipment between retailers in a competitive environment confirming previous simulation studies.

Abstract:
Voltage instability is a major concern in operation of power systems and it is well known that voltage instability and collapse have led to blackout or abnormally low voltages in a significant part of the power system. Consequently, tracking the proximity of the power system to an insecure voltage condition has become an important element of any protection and control scheme. The expected time until instability is a critical aspect. There are a few energy management systems including voltage stability analysis function in the real-time environment of control centres, these are based on assumptions (such as off-line models of the system loads) that may lead the system to an insecure operation and/or poor utilization of the resources. Voltage instability is driven by the load dynamics, and investigations have shown that load restoration due to the on-load tap changer (OLTC) action is the main cause of the voltage instability. However, the aggregate loads seen from bulk power delivery transformers are still the most uncertain power system components, due to the uncertainty of the participation of individual loads and shortcomings of the present approaches in the load modeling. In order to develop and implement a true on-line voltage stability analysis method, the on-line accurate modeling of the higher voltage (supply system) and the lower voltage level (aggregate load) based on the local measurements is required. In this research, using the changes in the load bus measured voltage and current, novel methods are developed to estimate the supply system equivalent and to identify load parameters. Random changes in the load voltage and current are processed to estimate the supply system Thevenin impedance and the composite load components are identified in a peeling process using the load bus data changes during a large disturbance in the system. The results are then used to anticipate a possible long-term voltage instability caused by the on-load tap changer operation following the disturbance. Work on the standard test system is provided to validate the proposed methods. The findings in this research are expected to provide a better understanding of the load dynamics role in the voltage stability, and improve the reliability and economy of the system operation by making it possible to decrease uncertainty in security margins and determine accurately the transfer limits.

Abstract:
Die elektrische Energieform gewinnt im Kraftfahrzeug wegen ihrer Nutzungsvielfalt und sehr guten Steuerbarkeit für die Realisierung neuartiger Funktionen zunehmend an Bedeutung. Voraussetzung für ihren Einsatz ist eine zuverlässige und effiziente Bereitstellung durch das Kfz-Energiebordnetz. Dafür ist ein intelligentes Energiemanagement erforderlich, welches mit geeigneten Strategien die Leistungsflüsse im Energiesystem koordiniert. In dieser Arbeit werden die beiden Entwurfsziele der Zuverlässigkeit und der Effizienz bei der Entwicklung von elektrischen Energiemanagement-Strategien systematisch betrachtet. Es erfolgt eine Beschreibung und Zuordnung der einzelnen Ziele und Maßnahmen anhand der Energieflüsse und Wirkungsketten. Ein Schwerpunkt bildet dabei die Beherrschung von Lastwechseln im Bordnetz. Für Aussagen hinsichtlich einer effizienten Erzeugung elektrischer Energie erfolgt eine Untersuchung der Energiewandlungskette anhand analytischer Methoden und mit Hilfe einer simulationsgestützten Optimierung. Ein weiterer Fokus der Arbeit liegt in der Betrachtung zur Anwendung ökonomischer Modelle für eine Energiekoordination. Es werden die theoretischen Grundlagen der Mikroökonomie zusammengestellt und mögliche Funktionsstrukturen eines einseitigen und zweiseitigen Allokationsmechanismus verglichen und bewertet. Abschließend zeigen experimentelle Untersuchungen an einem Bordnetzprüfstand zum Lastwechselverhalten und die Integration eines Energiemanagement-Systems den praktischen Bezug zum realen System.

Abstract:
У дисертаційній роботі здійснено комплексний аналіз особливостей функціонування ЛСЕП з врахуванням сучасних вимог концепції Smart Grid та виконано співставний аналіз методів оцінки обмінних процесів у ЛСЕП з джерелами РГ. На основі експертного аналізу виділено основні проблеми роботи ЛСЕП у вітчизняних системах електропостачання та енергозабезпечення. Розширено відому систему ПЯЕ для адекватного оцінювання рівнів ЕМС в ЛСЕП з дотриманням вимог концепції Smart Grid та оцінювання рівнів перетоків енергії на основі відомих показників. Розроблено та апробовано спеціалізований програмний модуль та нормативно-методичне забезпечення розширеного енергетичного аудиту з використанням обмінної потужності, яке дає змогу: визначити обмінну потужність та частку взаємного впливу в довільному перетині ЛСЕП з врахуванням особливостей їх конфігурації, режимів роботи окремих елементів та ЛСЕП в цілому; отримати інформацію про обмінні процеси в ЛСЕП з різним рівнем інформаційного забезпечення; адекватно враховувати особливості протікання режимів у ЛЕС, зокрема, двонаправленість потоків електроенергії та визначити реальний їх розподіл в елементах ЛСЕП.
In the dissertation the complex analysis of the peculiarities of functioning of local power supply systems (LPSS) is carried out taking into account the modern requirements of the Smart Grid concept and the comparative analysis of methods of estimation of exchange processes in LPSS with dispersed energy sources is performed. The need to extend the known LPSS system to adequately assess the EMC levels in the LPSS with the requirements of the Smart Grid concept and to estimate the energy flow rates using known indicators is justified. The analysis of exchange processes of LPSS under the influence of different types of impulse disturbances and sources of non-sinusoidal voltage and current caused by the peculiarities of modes of operation of both individual elements and the system as a whole for single and three-phase cross sections of LPSS is carried out. New relationships were obtained to evaluate the effect of non-sinusoidality and to take into account the ripple coefficients on the nature of the exchange processes. The analysis of the exchange processes in LPSS has been carried out taking into account the real characteristics of the elements with electromagnetic bonds (transformers, reactors, transmission lines, etc.) and new relationships have been obtained, which link the exchange power and the coefficients of magnetic coupling for one and three-phase LPSS operating in both sinusoidal and non-sinusoidal modes, as well as in symmetric and asymmetric modes. Regulatory and methodological support of the expanded energy audit with the use of exchange power was developed and tested. Regulatory and methodological support was used: for conducting an expanded energy audit at the enterprise of СE «Vasylkiv Leather Company» (Vasylkiv, Kyiv region); analysis of parallel operation of standby power supply systems both separately and in combination with the network used for powering server equipment of PLC «Prostonet»; was the basis for the course of lectures on discipline "Electrical Engineering Complexes", which will be taught in 2019 at Vasylkivsky College of NAU. A specialized software module and regulatory and methodological support for the extended energy audit using exchange power have been developed and tested. The proposed regulatory and methodological support makes it possible to: determine the exchange power and the proportion of mutual influence in an arbitrary intersection of LPSS, taking into account the peculiarities of their configuration, modes of operation of individual elements and LPSS as a whole; to obtain information on exchange processes in the LPSS with different levels of information support; to adequately take into account the peculiarities of the flow of modes in the LPSS, in particular, the bidirectionality of electricity flows and to determine their real distribution in the elements of LPSS.

Power supply is the most critical unit in an airplane. A defect in a power supply might lead to a crash. Therefore, it is very useful and important to monitor the status of the airplane's power supply during flight. This paper presents a real-time evaluation system constructed by a central process unit for processing and detecting defects and several remote units for acquiring parameters. Because of the huge amount of data acquired, a combination of Ethernet and time division multiplexing technique has been applied for constructing a 2.5Gbps synchronous data transportation network for the system.

Abstract:
In order for economically viable distributed generation systems for local community to spread, it is essential to develop an efficient and low-cost heat supply system. We propose a new heat supply system called DREAMS (Distributed Residential Energy with Advanced Management System). The key technology for the system is to connect compact heat supply units installed in all the households of the local community, such as a condominium, by a single loop of hot water piping. Two methods to decrease the heat supply rate through the single loop are proposed in this paper. The one is an utilization of a compact heat supply unit with heat storage in each house. The momentary heat demand can be covered by the heat storage. The other is a tap water preheating. A new CO2 regenerative heat pump cycle was proposed for the recover of the low temperature heat from the generator. A new heat supply unit with a practical capacity was manufactured, and the heat supply performance was evaluated by some experiments. Furthermore, an advanced energy management system has been under consideration to realize the effective system operation by utilizing IT. In this paper, experimental results on the performance of the new heat supply unit, the new CO2 heat pump system and evaluation of the energy-saving effect of our DREAMS are presented.

Abstract:
Micro-combined heat and power (MCHP) systems generate heat and electricity concurrently, making them an ideal addition for home and small/medium business owners to generate their own electricity and replace conventional natural gas-burning boilers. Combining MCHP units with thermal and electric storage systems can aid in decoupling supply and demand of energy. In such a combined setup, MCHP units can run for prolonged periods when they not only cover existing demand but charge storage systems for deferred consumption of energy. In the present work, we analyzed such an MCHP system, with a particular focus on integrating electrical storage systems and the resulting degree of electrical self-sufficiency achievable under realistic working conditions. We implemented a system control logic to optimize MCHP unit run time geared towards taking energy storage system charging levels into account. We demonstrate that an MCHP unit and electrical storage system can complement each other benefitting overall system performance. Separating days according to their respective degree of electrical self-sufficiency enabled us to identify supply composition characteristics that result in higher electrical load coverage by MCHP-generated electricity.

Abstract:
The article presents the results of research on the evaluation of electromagnetic compatibility of elements of the power supply system for Autonomous low-power consumers. The subject of the study is a quantitative assessment of the level of harmonic components of currents and voltages in systems: a permanent magnet generator-a DC-to-AC Converter-a consumer with a nonlinear load and interfering interaction of jointly working elements of this system. The level of harmonics of voltage and current in the local electrical network (farm), repeatedly (from 3 to 10 times) exceeds the regulatory requirements. The multiplicity of the increase in electrical energy losses (K-Factor) is from 5("pure" sine of the DC-AC Converter) to 20 (rectangular meander). When designing Autonomous systems, it is necessary to provide measures to reduce the loss of electrical energy, exit from standing electrical equipment and false triggering of electronic devices in the consumer of electric energy

Abstract:
Abstract The nature of Oil and Gas production presents numerous challenges for creating and maintaining reliable electrical infrastructure. Production assets are often widely dispersed over remote geographical areas, leaving them vulnerable to wildlife, storms and poor load management. Unfortunately for ESPs, even an extremely short interruption in electrical service can lead to significant downtime, stress on equipment, and additional field labor costs. The economic and operational advantages to providing a readily available, alternative source of power during these short duration events is significant. This paper describes an effective, economical approach that is based on locally situated energy storage with the appropriate control circuitry. The existing Variable Speed Drive (VSD) architecture allows for the storage system to be constantly connected to the ESP's electrical system, allowing for an ever-present power supply without the need for mechanical switching. The ride-through system was designed to keep a fully loaded ESP system, of corresponding size, operational during most temporary power disturbances. At the conclusion of rigorous laboratory testing, the ride-through system was installed in the field and was subjected to simulated outages. Precision electrical monitoring equipment was installed to record voltage and current during genuine disruptions and interruptions. Records from field testing and genuine events confirmed the viability of local storage systems utilizing supercapacitors. The energy storage system provided a steady supply of power and consistently prevented shutdowns during common power system disruptions. Due to its capacity to store a considerable amount of power, the system demonstrated an ability to ride-through both multiple disturbances in short succession as well as outages lasting as long as 8 seconds, even under full load.
