The assimilation of Distributed Generation (DG) into the electric power system (EPS) has become more attractive as the world is following a trend to reduce greenhouse gas emissions by introducing more renewable energy forms resulting in high penetration scenarios. This high penetration of DGs brings several challenges to the protection philosophy of the EPS which compromises its reliability, availability, and efficiency. Under high DG penetration scenarios, conventional islanding detection methods (Idms) fail to detect an island as the grid loses its inertia to leverage a significant frequency and voltage mismatch necessary for Idms to effectively detect an islanding event. This has given rise to the birth of Artificial Intelligent (AI) methods that are found to perform better in islanding detection. AI Idms are computationally intensive and require a lot of data to operate accurately. Because the computational burden of these methods requires fast computing hardware, the current trend of AI Idms are integrated with Wide Area Monitoring, Protection, and Control (WAMPAC) system. This paper aims at reviewing all these Idms and the WAMPAC’s system latency when hosting AI Idms which are currently the best in islanding detection. This is done to determine if the WAMPAC system latency plus Idms computational time meet the islanding detection time specified by the IEEE Standard 1547 framework.

Distribution medium voltage networks have a branched structure, many power centers, longcable and overhead lines. This complicates the process of their automation, since significant capital costs for new equipment are required. New solutions based on modern technologies can help speed up this process and make it more efficient. The authors propose the use of synchronized phasor measurement technology for automating medium voltage networks. This paper considers approaches that describe the possibilities of implementing the WAMPAC principles in such networks, provides several examples where these principles apply.

The renewed quest for situational awareness in power systems has brought about the use of digital signal processing of power system measurements, and the transmission of such data to control centres via communication networks. At the control centres, power system stability algorithms are executed to provide monitoring, protection, and control in order to prevent blackouts. This can be achieved by upgrading the existing Supervisory Control and Data Acquisition (SCADA) systems through the deployment of newly proposed power system synchrophasor-based applications for Wide Area Monitoring, Protection, and Control (WAMPAC). However, this can only be done when there is a complete understanding of the methods and technologies associated with the communication network, message structure, and formats required. This paper presents an analysis of the IEEE C37.118 synchrophasor message framework, message formats, and data communication of synchrophasor measurements from Phasor Measurement Units (PMUs) for WAMPAC schemes in smart grids. A newly designed lab-scale testbed is implemented and used in the practical experimentation relating to this paper. Synchrophasor measurements from the PMUs are captured using a network protocol analyzer software-Wireshark, and the compliance of the synchrophasor message structures and formats captured was compared to the specifications defined in the IEEE C37.118 synchrophasor standard.

Angle stability appears in many forms in transmission network. There are small active power oscillations which do not endanger the normal operations whereas medium and large oscillations have implications on normal operations. These latter kinds of oscillations in some cases develop in out of step condition, which is dangerous disturbance with serious impact on transmission network and generating units. Transmission network operator’s challenges and obligations are to treat in the right manner angle stability issues in their network. Controlling and protecting network needs to be done in efficient way in order to disconnect disturbance quickly and prevent abnormal network operation without exporting disturbance in surrounding networks. Synchrophasor measurements in control centre offer a platform, which responds in a new way on angle stability in transmission network. Those measurements which are collected in phasor data concentrators, which is a part of Wide Area Monitoring will be used for creating out of step protection. This is the first step to extended system to Wide Area Monitoring Protecting And Control (WAMPAC). Paper gives progress of such project in Croatian Transmission Network Operator (HOPS). Firstly, there will be stated motives for development of new out of step protection based on synchrophasor measurements. Some feasibility aspect elaborated with emphasis on communications latency. Furthermore, designed Matlab model for transmission network and protection with small portions of simulations results and analyses presented in paper reveal potential of proposed solutions. This new protection is based on using voltage angles values from phasor data stream in phasor data concentrator.

This article presents a study on real-time testing of synchrophasor-based “wide-area monitoring system’s applications (WAMS application).” Considering the growing demand of real-time testing of “wide-area monitoring, protection, and control (WAMPAC)” applications, a systematic real-time testing methodology is formulated and delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for its acceptance prior to implementation into a production system. However, only one stage is demonstrated in this article which comprises the use of a prototyping software toolchain and whose potential is assessed as sufficient for preliminary real-time testing (PRTT) of WAMS applications. The software toolchain is composed of two components: the MATLAB software for application prototyping and other open-source software that allows ingesting prerecorded phasor measurement unit (PMU) signals. With this software toolchain, a PRTT study is presented for two WAMS applications: “testing of the PMU/phasor data concentrator (PDC)” and “testing of wide-area forced oscillation (FO) monitoring application.”

Many wide area monitoring, protection, and control (WAMPAC) systems are being deployed by grid operators to deal with critical operational conditions that may occur in power systems. Thanks to the real-time measurements provided by a set of distributed phasor measurement units (PMUs), different protection algorithms can be run in a central location. In this context, this article presents and validates a novel method that can be used as a backup protection for a selected area in a power system. It merges the integrated impedance angle (IIA) protection method with the theory of virtual buses in wide area electrical power systems. The backup protection works this way: once a fault is detected (pickup time), another delay (added to the pickup time) is defined in order to wait for the primary protection to act. If this does not happen, the algorithm generates its backup trip. The proposed method has been called the zone integrated impedance angle (Zone IIA). A real-time PMU laboratory has been used to test the proposed algorithm using a real-time digital simulator (RTDS). The algorithm has been programmed in a real-time automation controller (RTAC). It has been tested in two different simulated setups: first, a 400 kV transmission system, with and without the use of renewable energy sources (RES); second, a 150 kV submarine line between the Greece mainland and an island, which is currently the longest submarine alternating current connection in the world. The results obtained during the tests have yielded tripping times for area protection in the order of 48 ms, if no time delay is used between the fault detection and the trip order. According to the test results, the proposed method is stable, reliable, obedient, and secure, also with RES installed in the power system. Additionally, the method is selective, i.e., during the tests no trip was executed for external faults, no trip was executed in no-fault condition, and all the applied internal faults were detected and tripped correctly. Finally, the protection method is easy to implement. The method is also applicable to protection against short circuits in distribution systems. According to the trip times observed during the tests, it is clear that these algorithms are well suited to implement backup protections in transmission grids, even in scenarios with high penetration of renewable energies. Considering that backup trip times in transmission grids are usually set between 400 and 1000 ms, and that the actuation times obtained by the proposed algorithm are under 100 ms, the method is suitable for its use as a backup protection.

System integrity protection schemes (SIPS) are schemes that can, under potentially hazardous conditions, prevent a complete blackout of endangered parts of an electrical power system (EPS). The main objective of SIPS is to monitor the state of the power transmission network in real time and to react in emergency cases. This paper explores the use of phasor measurement unit (PMU) technology for the development of SIPS as a part of wide-area monitoring, protection, and control (WAMPAC) systems. A new SIPS development method is described using the experience from the real-time operation. The developed optimal bus-splitting scheme identifies potential actions that can eliminate or reduce power system overloads and protect the integrity of the power system. An optimal bus-splitting scheme based on a DC power flow model and PMU measurements is given as an example and is explained and tested on an IEEE 14 bus test system. Conducted simulations indicate that the described SIPS methodology supported by the PMU measurements can mitigate potential overloads of the observed network part.

This paper reports on the construction and characterization of an optical voltage transducer module for applications in the field of wide-area monitoring, protection, and control (WAMPAC). The optical medium voltage transducer (MVT) module was designed to be combined with a capacitive voltage divider (CVD) to form a voltage sensor intended for 132 kV high voltage (HV) networks. The MVT module comprises a combination of a piezoelectric transducer (PZT) and a fiber Bragg grating (FBG) as a core optical sensing element. Changes in the input voltage across the PZT translate into strain being detected by the FBG. The resultant FBG peak wavelength can be calibrated in terms of the input voltage to obtain a precise voltage measurement. The module was experimentally evaluated in the laboratory, and its performance was assessed based on the requirements specified by the IEC standards for electronic voltage transformers and low power voltage transformers. The results of accuracy tests demonstrate that the MVT module is free from hysteresis, within the experimental error, and is capable of simultaneously meeting the requirements for 0.1 metering and 1P protection classes specified by the IEC 60044-7 and IEC 61869-11 standards.

The electrical utility, which has traditionally been a centralised predictable system, is now changing to becoming a decentralised, more dynamic system with increasing distributed generation and changeable load patterns; not to mention widespread EV on the horizon. With these changes, there is an increased desire for WAMPAC to aid in managing this complex dynamic system, particularly at the distribution and prosumer level - where this framework is aimed. This thesis presents a novel communications framework to support these next-generation smart grid applications. Taking Synchrophasor data as a case-study due to its potential uses for both real- and non-real-time applications, issues are identified with existing protocols used to represent and deliver this data. From these issues, requirements are identified for data transport next generation applications. Reliability, extensibility and security are identified as key components for WAMPAC systems. These requirements act as a metric to help decide between various technologies for message formatting, and transport - which is essentially the core of WAMPAC communications. Upon investigation of the current state of the art in communications systems data representation and data transport mechanisms are selected. Namely, JSON/Protobuf for extensible message formatting, and MQTT publish/subscribe protocol as a secure, reliable and scalable delivery mechanism. The latter part of the thesis describes the implementation and testing stages that solidify the suitability of JSON and MQTT for WAMPAC communications. There is no literature to date that presents such an approach to the challenges of next-generation smart grid communications. Many of the key ideas and concepts presented in this thesis have been accepted in peer reviewed publications.

The ever increasing complexity of the electrical grid has made it difficult to predict and anticipate contingencies. This is mainly due to the advent of deregulated electricity markets, aging transmission infrastructure and the growing penetration of renewable resources. The wave of blackouts in recent years has made utilities much more aware of the need for power system wide monitoring and control. One of the fundamental requirements to achieve that goal is to have common measurement reference. A few technology enablers have emerged which have led to development of a new kind of measurement paradigm; Phasor Measurement Units, or PMUs. PMUs bear high potential for wide-area system monitoring and control as well for conducting advanced engineering analysis. PMUs can provide time-synchronized high-resolution estimates of voltage and currents (both phase amplitude and angle) as well as frequency and rate of change of frequency. Such measurements, alternatively called synchrophasors, can provide visibility of a power system distributed over a wide geographical area and can be utilized in a multitude of applications including real-time monitoring, advanced power system protection, and advanced control schemes. In this thesis, a new special protection scheme (SPS) is proposed based on synchronized measurements provided by PMUs. An existing remedial action scheme (RAS) protecting for contingencies impacting the tie-line interconnecting the Alcan system to B.C. Hydro, using conventional relays is studied, and a new scheme based on time-synchronized, and high-resolution voltage angle measurements from PMU’s in a Wide-are monitoring system (WAMs) is proposed . In this new scheme, the angles of the buses at large power plants in both systems are examined and used to calculate various criteria based on region center of angle and the kinetic energy function to implement RAS. The results of a number of time domain simulations demonstrate that the proposed scheme can lead to faster operation of the SPS and decreased amount of generation and load shedding in the Alcan system. The achieved speed and efficiency of the proposed scheme in comparison to the existing installed scheme further highlight the opportunity in utilizing PMU measurements in online applications for power system protection and monitoring.

The growing issue of power-grid congestion and a global increase in disturbances have emphasized the need to enhance electrical power networks using Wide Area Monitoring, Protection, and Control (WAMPAC). This is a cost-effective solution for improving power system planning and operation. In addition to these existing issues, the Great Britain (GB) power system is facing significant changes, in terms of both power transmission technology and the nature of the generation mix, that will cause the operation of the future GB power system to become more unpredictable and complex. Therefore, developing a WAMPAC system will be essential to enhance the stability and optimise the operation of the future GB power system. The main objectives of the research presented in this thesis are to design a GB WAMPAC system and develop solutions to overcome the challenges that will be involved in the initial stage of the GB WAMPAC project. As Synchronized Measurement Technology (SMT) is the most essential element and enabler of WAMPAC, this thesis first provides a study of SMT and its applications. This study also reviews the state of the art of these SMT applications, and worldwide experience with the operation of WAMPAC in terms of system architecture, communication technologies and data management. After the basic study of WAMPAC, this thesis presents a new methodology for designing a roadmap that will ensure the future GB WAMPAC system will be developed in a logical and economic manner. This methodology takes into account the international experience with WAMPAC project management and the practical challenges faced in the future GB power system. With this new methodology, the GB strategies for the development of WAMPAC are devised. Two major SMT applications are then developed that can form main parts of the proposed future GB WAMPAC system. These applications are developed to enhance the small signal stability of the future GB power system.1. Wide Area Inter-area Oscillation Monitoring using Newton Type Algorithm.2. Wide Area Inter-area Oscillation Control using Power Electronic Devices. Finally, the operation of a proposed GB WAMPAC system is demonstrated using the DIgSILENT software package. The proposed real time applications are tested and evaluated using dynamic simulations of a full GB power system model. In addition, some key factors that will influence the operation of the future GB WAMPAC system will be analyzed and discussed.

This thesis describes and computationally tests a method of using PMU data to generate an optimisation metric that accurately reflects the desirability of a given power system's operating conditions. The optimisation function takes into consideration the voltage profile across the network, reactive power flow, transmission losses and line loading. The optimisation function was investigated as a wide-area control variable for on load tap changing transformers and switched shunt capacitors. Networks whose control assets were optimised with this wide-area optimisation metric were found to be able to handle a greater load and distributed generation before acceptable operating conditions were infringed. The wide-area controlled networks, that were modelled in PSSE, were also found to have a consistently higher efficiency, a better voltage profile and to be more resilient against voltage instability. The initial testing of the optimisation method assumed complete observation of the network in question. The investigation continues to demonstrate how a regression method could be used to extrapolate the global optimisation metric from a limited number of PMU placements on the system. A parsimonious multivariate linear regression method is developed that suggests the best PMU placements and quantifies the degree of error that might result from the reduced visibility. The optimisation function is intended as a method of reducing a profusion of PMU data down to a single simple metric. The optimisation metric can be quickly interpreted by a network operator, its variation used to inform the operation of assets or the desirability of specific asset operation. The metric could easily be transported over legacy SCADA systems, given its small size and the lack of reliance on a reporting rate. The intention of this work is facilitate a power system that can operate more efficiently, handle more distributed generation and provide a better service.

Fault tolerance and dependability are of high importance to the information infrastructure that supports and controls the operation of the Critical Infrastructure such as the electrical power grid and telecommunication systems due to their vital role in the proper function of society and economy. This thesis examines GridStat, an established middleware approach for providing fault tolerance and dependability and performs a constructive evaluation of its architectural design. It, then, builds upon this approach providing an enhanced solution, Pe- GridStat that uses peer to peer networks to overcome a number of the inherent shortcomings and thus offers a better degree of fault tolerance. The architecture of the proposed approach is discussed in detail where it is shown that the proposed approach which mitigates by design the shortcomings of the original one regarding fault tolerance and availability. A comparative and qualitative evaluation of the original and the proposed approaches is performed using a realistic infrastructure , the power transmission network of New Zealand. This evaluation reveals that apart from addressing the aforementioned issues, the proposed approach offers also improvements with regards to timeliness requirements and imposed overhead to the underlying communication networks.

Modern power networks incorporate communications and information technology infrastructure into the electrical power system to create a smart grid in terms of control and operation. The smart grid enables real-time communication and control between consumers and utility companies allowing suppliers to optimize energy usage based on price preference and system technical issues. The smart grid design aims to provide overall power system monitoring, create protection and control strategies to maintain system performance, stability and security. This dissertation contributed to the development of a unique and novel smart grid test-bed laboratory with integrated monitoring, protection and control systems. This test-bed was used as a platform to test the smart grid operational ideas developed here. The implementation of this system in the real-time software creates an environment for studying, implementing and verifying novel control and protection schemes developed in this dissertation. Phasor measurement techniques were developed using the available Data Acquisition (DAQ) devices in order to monitor all points in the power system in real time. This provides a practical view of system parameter changes, system abnormal conditions and its stability and security information system. These developments provide valuable measurements for technical power system operators in the energy control centers. Phasor Measurement technology is an excellent solution for improving system planning, operation and energy trading in addition to enabling advanced applications in Wide Area Monitoring, Protection and Control (WAMPAC). Moreover, a virtual protection system was developed and implemented in the smart grid laboratory with integrated functionality for wide area applications. Experiments and procedures were developed in the system in order to detect the system abnormal conditions and apply proper remedies to heal the system. A design for DC microgrid was developed to integrate it to the AC system with appropriate control capability. This system represents realistic hybrid AC/DC microgrids connectivity to the AC side to study the use of such architecture in system operation to help remedy system abnormal conditions. In addition, this dissertation explored the challenges and feasibility of the implementation of real-time system analysis features in order to monitor the system security and stability measures. These indices are measured experimentally during the operation of the developed hybrid AC/DC microgrids. Furthermore, a real-time optimal power flow system was implemented to optimally manage the power sharing between AC generators and DC side resources. A study relating to real-time energy management algorithm in hybrid microgrids was performed to evaluate the effects of using energy storage resources and their use in mitigating heavy load impacts on system stability and operational security.

This dissertation embodies a comprehensive approach towards resilient monitoring of frid events using Structure Preserving Energy Functions (SPEFs) and introduces a novel control architecture in Multi Terminal Direct Current (MTDC) grids, for inter-area oscillation damping and achieving robustness to AC as well as DC side, post-contingency events in the modern power grid. This work is presented as a collection of several publications which investigate and address the proposed research topics. At first, SPEFs are derived for multi-machine IEEE benchmark models with the help of the Wide-Area Measurements (WAMs). A physics-based hybrid approach to develop one-to-one mapping between properties of energy function components with respect to the type of fault in the system is introduced. The proposed method is tested offline on a IEEE-39 bus, New England Test System (NETS), with particular interest in monitoring the most sensitive energy functions during relay misoperations. Such events can be precipitated by zone 3 trips in distance relays due to load encroachment during stressed conditions. These might include a genuine misoperation, a false trip due to cyber-attacks, or a load encroachment, all of which are undesirable under normal operating circumstances. An online monitoring scheme is introduced in an actual blackout simulation in the Western Electricity Coordinating Council (WECC) to examine what further indications these energy function components can provide, especially during a cascading sequence, and how they could supervise critical tripping decisions by distance relays. Next, a futuristic grid comprised of Voltage Source Converter (VSC) based AC-MTDC is considered due to its recent proliferation in integrating offshore wind farms to onshore grids, and additionally improving strength of weak AC grids. A robust control is designed using the converter station poles as actuators to provide damping support to the surrounding AC grid. Further, a design problem is envisioned and implemented that introduces disturbance rejection into control architecture by designing a novel explicitly modeled disturbance plant in the Linear Matrix Inequality (LMI) framework. Finally, a novel robust inter-area oscillation damping controller is designed that proves its effectiveness in inter-area mode settling times, and provides robustness to (n-1) contingencies in the AC as well as the DC side of the meshed AC-MTDC grid.

Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. This thesis focuses on the design, development and experimental validation of WAMPAC applications, and investigates their vulnerability to time synchronization impairment. To this purpose, a state-of-the-art real-time hardware-in-the-loop (RT-HIL) test-bench was established for prototyping of synchrophasor-based applications. This platform was extensively used throughout the thesis for end-to-end testing of the proposed WAMPAC applications. To facilitate the development of WAMPAC applications, an open-source real-time data mediator is presented that parses the incoming synchrophasor stream and provides access to raw data in LabVIEW environment. Within the domain of wide-area protection applications, the thesis proposes hybrid synchrophasor and IEC 61850-8-1 GOOSE-based islanding detection and automatic synchronization schemes. These applications utilize synchrophasor measurements to assess the state of the power system and initiate protection / corrective action using GOOSE messages. The associated communication latencies incurred due to the utilization of synchrophasors and GOOSE messages are also determined. It is shown that such applications can have a seamless and cost-effective deployment in the field. Within the context of wide-area control applications, this thesis explores the possibility of utilizing synchrophasor-based damping signals in a commercial excitation control system (ECS). For this purpose, a hardware prototype of wide-area damping controller (WADC) is presented together with its interface with ECS. The WADC allows real-time monitoring and remote parameter tuning that could potentially facilitate system operators’ to exploit existing damping assets (e.g. conventional generators) when changes in operating conditions or network topology emerges. Finally the thesis experimentally investigates the impact of time synchronization impairment on WAMPAC applications by designing RT-HIL experiments for time synchronization signal loss and time synchronization spoofing. It is experimentally demonstrated that GPS-based time synchronization impairment results in corrupt phase angle computations by PMUs, and the impact this has on associated WAMPAC application.

Traditionally, monitoring and control functions in large power systems were based on measurements obtained locally. While small disturbances have their impact con ned locally to the area of disturbance, large disturbances impact the system performance on a larger geographical scale. Preventive / Control actions based on local measurements may not be completely e ective in detecting/ preventing impinging wide scale distur-bances leading to blackouts. This brought about the need to monitor the state of the system through measurements made at various locations which led to the development of Wide Area Monitoring, Protection and Control (WAMPAC). Compared to traditional Supervisory Control and Data Acquisition (SCADA), WAMPAC is expected to improve both accuracy and reporting rates of the measurements. In addition, the measurements in WAMPAC are time stamped which can aid in post disturbance processing. At the heart of the WAMPAC, is the Phasor Measurement Unit (PMU). Phasor Measurement Units are devices that measure synchronized phasor, frequency and rate of change of frequency from voltage/current signals. This work focuses on two key computational aspects in PMU i.e. frequency and phasor estimation. The bench-marks required in terms of accuracy and other speci cations under quasi steady state and dynamic conditions are outlined by the IEEE C37.118.1-2011 standard for synchrophasor measurements. Discrete Fourier Transform (DFT) with moving window is traditionally used for the estimation of fundamental frequency phasor. This method provides a good estimate even in the presence of harmonics, but tends to be inaccurate due to the pres-ence of noise in measurements and the decaying DC component which occur during faults. Although, several improved algorithms to estimate the phasor and frequency in compliance with the IEEE C37.118.1-2011 standard are proposed in literature, further improvements are possible. In this thesis, algorithms to accurately estimate frequency and phasor particularly under dynamic conditions are proposed. In the rst part of this work, a frequency estimation algorithm based on interpolation of coe cients of Discrete Fourier Transform (DFT) is proposed. In particular, the magni-tude of DFT coe cients corresponding to the fundamental frequency along with DC and second harmonic are used to accurately estimate the frequency of the voltage/current signal. Subsequently, the second part of the work focuses on phasor estimation under tran-sient conditions and at o nominal frequencies. With this objective, two algorithms which o er advantages over the existing approaches are proposed in this thesis. The rst algorithm is based on interpolation of DFT coe cients while the second algorithm is based on time domain interpolation with resampling. The frequency and phasor estimation algorithms proposed in this work are extensively tested using standard test signals and simulated voltages/currents of real life systems. For testing the accuracy of the proposed algorithm for real life systems, voltage and current signals obtained using Electromagnetic Transients Program (EMTP) for a 765 kV system and a 24 bus EHV equivalent system of a part of Indian Southern grid are considered. The estimated frequency and phasor of these signals are found to be in compliance with the IEEE C37.118.1-2011 standard.
