AGC structures for regional interconnected grids with AGC signal delays

Yang Li

Abstract

It is one of the basic policies for the power market reforming in China to build and run large regional power market,and consequently it is essential to work out the appropriate AGC structures.Based on the AGC operation experience both at home and abroad,six kinds of AGC structures are summarized.With the dynamic frequency simulation method,the frequency control of the multi-area AGC mode is studied emphatically.The AGC PI coefficients are optimized,and the influence of AGC signal delays on AGC performance is analyzed.At last,the dynamic frequency simulation and analysis based on some actual system load data and operation methods are carried out.
