Wide area monitoring, protection and control systems (WAMPACs) have been recognized as the most promising enabling technologies to meet challenges of modern electric power transmission systems, where reliability, economics, environmental and other social objectives must be balanced to optimize the grid assets and satisfy growing electrical demand. To this aim WAMPAC requires precise phasor and frequency information, which are acquired by deploying multiple time synchronized sensors, known as Phasor Measurement Units (PMUs), providing precise synchronized information about voltage and current phasors, frequency and rate-of-change-of-frequency.

POWER SYSTEM MONITORING AND CONTROL An invaluable resource for addressing the myriad critical technical engineering considerations in modern electric power system design and operation Power System Monitoring and Control (PSMC) is becoming increasingly significant in the design, planning, and operation of modern electric power systems. In response to the existing challenge of integrating advanced metering, computation, communication, and control into appropriate levels of PSMC, Power System Monitoring and Control presents a comprehensive overview of the basic principles and key technologies for the monitoring, protection, and control of contemporary wide-area power systems. A variety of topical issues are addressed, including renewable energy sources, smart grids, wide area stabilizing, coordinated voltage regulation and angle oscillation damping—as well as the advantages of phasor measurement units (PMUs) and global positioning system (GPS) time signal. Analysis and synthesis examples, along with case studies, add depth and clarity to all topics. Provides an up-to-date and comprehensive reference for researchers and engineers working on wide-area PSMC Links fundamental concepts of PSMC, advanced metering and control theory/techniques, and practical engineering considerations Covers PSMC problem understanding, design, practical aspects, and topics such as smart grid and coordinated angle oscillation damping and voltage regulation Incorporates the authors’ experiences teaching and researching in international locales including Japan, Singapore, Malaysia, and Australia Power System Monitoring and Control is ideally suited for a graduate course on this topic. It is also a practical reference for researchers and professional engineers working in power system monitoring, dynamic stability and control.

This book proposes new control and protection schemes to improve the overall stability and security of future wide-area power systems. It focuses on the high penetration levels of renewable energy sources and distributed generation, particularly with the trend towards smart grids. The control methods discussed can improve the overall stability in normal and abnormal operation conditions, while the protection methods presented can be used to ensure the secure operation of systems under most severe contingencies. Presenting stability, security, and protection methods for power systems in one concise volume, this book takes the reader on a journey from concepts and fundamentals to the latest and future trends in each topic covered, making it an informative and intriguing read for researchers, graduate students, and practitioners alike.

One of the most challenges in the development of smart grids today is the presence of phasor measurement units with modern communication facilities. The presence of such technologies will enable advanced smart grid applications that were not possible before such as the real time tracking of system dynamics. In addition, one of its goal issues is to maintain a high level of system stability. However, with rapid expansion of power system to meet the needs of the increasing demands of customers, and under the pressure of economical aspects placed by utilities to push the systems to operate very close to their limits, system wide disturbance become more likely. Therefore, the need for a systematic study and design of a comprehensive system control strategy is gaining more and more attention. Wide area protection is a concept of using system- wide information and sending selected local information to remote locations in order to mitigate the propagation of major disturbances. This book proposed a WAMPAC system with a defensive approach to counteract the transient instabilities in power systems. The system objective is to maximize the system stability and avoid occurrence of blackouts.

The interstate integration of power grids provides multiple advantages concerning operation security, integration of renewable energy as well as energy trading. Due to these facts grid interconnections, such as ENTSO-E in Continental Europe, expand continually since its establishment. Due to the increasing scale and distance of interconnected power systems as well as an increasing number of countries involved with increasing complexity of operation, comprehensive R&D and innovations are urgently required to assure reliable and efficient operation of power systems. In this book new tools and methods are presented for monitoring, control and protection of large scale power systems. These tools and methods consider Smart Grid technologies based on wide area data exchange in combination with modern measurement devices, such as PMUs and advanced network controllers such as FACTS and HVDC systems. Within this topic the impact and reliability of different communication technologies play a key role. The material of this book is based on final results from the international research project ICOEUR “Intelligent Coordination of Operation and Emergency Control of EU and Russian Power Grids”, supported by the European Commission and the Russian Federal Agency of Science and Innovation. This book provides a great value for professional power system engineers as well as for students interested in topics related to large scale power system monitoring, control, protection and operation.

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.
