Optimization Strategy of Under-Frequency Load Shedding For Pumped Storage Units in Power System
摘要
Abstract
The two strategies of urder-frequency load shedding for pumped storage units are introduced and compared.In order to maintain the stability of the power system frequency when the power system is subject to a large disturbance and a large power losses,the optimization strategy of under-frequency load shedding for pumped storage units is proposed.According to the frequency variation or the rate of change of frequency of the system,the shedding amount of the pumped storage units is determined,and the fast cutting pump unload is completed before the grid load shedding device act,so that to ensure the grid frequency in the normal operating range without taking measures to reduce the user's load.The simulation results show that the frequency recovery is faster,the lowest frequency point is relatively higher,and the under-frequency running time will be shortened when using the rate of change of frequency to determine the unloading amount of the cutting pump.关键词
