摘要：
To guarantee frequency and tie-line power control effect and make full use of AGC capacity resource, a coordinated AGC strategy for interconnected power grid is proposed based on cooperative game theory. Interconnected power system operation state is divided into different grades according to absolute value of frequency deviation. When system operates in different grades the way setting frequency bias coefficient is different, and AGC operations of different control areas can be coordinated. Profit models including AGC capacity demand profit model and frequency regulation obligation cost model are constructed for each control areas in AGC coordinated operation. When interconnected power system is in grade of coordination frequency control, frequency regulation obligation cost is adjusted through periodically changing setting of B coefficient calculated according to models of Shapley value and nucleolus in cooperative game theory, and the profits of all control areas are optimized. Simulations are conducted on three-area interconnected power system, verifying effectiveness of the proposed coordinated AGC strategy. © 2017, Power System Technology Press. All right reserved.
