[IEEE 2018 IEEE Conference on Control Technology and Applications (CCTA) - Copenhagen (2018.8.21-2018.8.24)] 2018 IEEE Conference on Control Technology and Applications (CCTA) - Retrofitting Based Power System Stabilizer Design of PV-Integrated Power Systems

摘要： In this paper, we propose a novel type of Power System Stabilizer (PSS) for power systems with large-scale photovoltaic (PV) integration. The proposed PSS can mitigate adverse impacts of short-term operation stoppage of PV generators on the overall power system dynamics. The advantage of the proposed PSS over conventional PSSs is that the damping performance of the overall power system is shown to be improved theoretically while the proposed PSS can be considerably lower-dimensional than the entire power system. The efficiency of the proposed PSS is shown through a numerical example of a PV-integrated benchmark model representing the bulk power system in the eastern half of Japan.
