Study and Analysis of Electric Vehicle Using Droop Controller to Support Frequency Deviation in Multimachine Power Systems
摘要
Frequency stability is one of the most critical characteristics for keeping the power system stable and reliable since it maintains the steady-state frequency after a considerable imbalance between generation and load. As a significant increase of electric vehicles (EVs) is expected in the future, this chapter focuses on study and impact of electric vehicle utilizing droop control mechanism to eliminate the frequency fluctuation caused by the load fluctuations. The IEEE 9-bus standard test system was adopted to show the effectiveness of the proposed controller. This chapter examines two case studies and compares them to frequency regulation control strategies. The system modeling and simulations are carried out by using DIgSILENT PowerFactory software.
