  • Application of PMUs to monitor large-scale PV penetration infeed on frequency of 60 Hz Japan power system: A case study from Kyushu Island

    Kerdphol T., Matsukawa Y., Watanabe M., Mitani Y.

     View Summary

    © 2020 Elsevier B.V. Recently, the large-scale photovoltaic (PV) penetration brings serious issues for system operators in monitoring and maintaining grid stability. The intermittent power output and loss of inertia property from high PV penetration critically affect the balance between generation and demand. These issues lead to larger frequency oscillations, generation tripping, and cascading failures. To overcome these challenges, this paper proposes an advanced application of phasor measurement units (PMUs) for monitoring dynamics of the system in the presence of high PV penetration. During such penetration, the data-driven analysis of the rate of change of frequency (ROCOF) is of great importance, reflecting the system stability. This approach is first demonstrated on Kyushu Island, and PMUs are installed at the domestic supply side. The contrastive scenarios of high-resolution PMUs recorded in each region are analyzed against different levels of PV penetration. The results reveal that monitoring system frequency and ROCOF variations not only indicate the oscillatory behavior of the grid, but also provide useful information for the wide-area dynamic stability. This paper also offers a recent overview of large-scale PV penetration infeed on frequency of the 60 Hz Japan power system, and it can be useful for improving a range of diagnostic/monitoring and control functionalities.

    © 2020, Springer Nature Switzerland AG. In this chapter, a comprehensive literature review on the issue of load frequency control (LFC) in the power system has been highlighted. The various power system model configurations and control techniques/strategies concerned with LFC problems have been discussed in both conventional and renewable power systems. In addition, the suggested LFC control strategies have been researched and classified into various control groups. Finally, the chapter highlights the study gaps and presents some new research directions in the field of LFC.

  • Dynamic Security Assessment of Low-inertia Microgrids Based on the Concept of Virtual Inertia Control

    Magdy G., Shabib G., Elbaset A.A., Mitani Y.

    Power Systems      59 - 87   2020.01  [Refereed]

     View Summary

    © 2020, Springer Nature Switzerland AG. Renewable energy sources (RESs) are growing rapidly and highly penetrated in microgrids (μGs). However, there are some impacts resulting from integrating RESs such as power fluctuations caused by the intermittent nature of RESs, and lack of system inertia resulting from replacement of synchronous generators with RESs. Hence, in order to cope with this challenge and benefit from a maximum capacity of the RESs, this chapter presents a new frequency control strategy based on a virtual inertia control to emulate virtual inertia into the μG control loop, thus stabilizing μG frequency during high penetration of RESs. Moreover, the proposed virtual inertia control system based on an optimal proportional–integral (PI) controller is coordinated with digital over/underfrequency relay to improve the frequency stability and maintain the dynamic security of the μG considering high penetration of RESs. The studied system simulation results are conducted using MATLAB/Simulink® software to validate the efficacy of the proposed coordination scheme. Results endorsed that the proposed coordination scheme can efficiently regulate the μG frequency and ensure robust performance to maintain the dynamic security of μG with high penetration of RESs for various contingencies.

  • Digital Decentralized Control Scheme in Multi-source Power Systems Based on Mapping Technique

     View Summary

    © 2020, Springer Nature Switzerland AG. This chapter presents a digital model of decentralized load frequency control (LFC) using an optimal PID controller in a real hybrid power system (e.g., Egyptian power system (EPS)) considering communication delays. The EPS includes both conventional generation sources (i.e., steam, gas, hydraulic power plants) with inherent nonlinearities and wind power, which is extracted from Zafarana wind farm, located in Egypt. Thus, the optimal digital controller-based Tustin’s technique is designed for every subsystem of the EPS separately to guarantee the stability of the overall closed-loop system. The efficiency of the proposed digital model is evaluated and compared with the analog model under variation in loading patterns, loading circumstances, system parameters, wind farm penetration, and communication delays. Results endorsed that the proposed digital model can effectively regulate the system frequency and guarantee robust performance under different conditions. It also provides a reliable performance at large sampling times, meaning a decrease in the cost of execution.

     View Summary

    © 2014 by John Wiley & Sons, Inc. All rights reserved.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 systems (GPS) time signal. End-of-chapter problems and solutions, along with case studies, add depth and clarity to all topics. Timely and important, Power System Monitoring and Control is an invaluable resource for addressing the myriad of critical technical engineering considerations in modern electric power system design and operation. Provides an updated and comprehensive reference for researcher and engineers working on wide-area power system monitoring and control (PSMC). Links fundamental concepts of PSMC, advanced metering and control theory/techniques, and practical engineering considerations. Covers PSMC problem understanding, design, practical aspects, and timely topics such as smart/microgrid control and coordinated voltage regulation and angle oscillation damping. Incorporates authors' experiences teaching and researching in various international locales including Japan, Thailand, Singapore, Malaysia, Iran, and Australia.
