摘要：
With the large-scale renewable energy integration, the system frequency instability has become more serious and the contradiction between frequency regulation demand and supply increasingly apparent. It is difficult for the existing single frequency regulation ancillary market to meet the system operation requirements. By review ing foreign ancillary service markets, a co-optimized unit commitment model is established with the primary and secondary frequency reserve considering the dynamic frequency constraints to improve the frequency response ability. Then this nonlinear problem is decomposed into a two-stage mixed integer linear programming problem by the L-shape method to realize the optimization. The lost opportunity cost compensation is further discussed. Finally, a simulation indicates the effectiveness of model, and the influence of the primary frequency regulation on market clearing cost and opportunity cost is discussed, which can provide reference for construction of frequency regulation ancillary service market. © 2020, Power System Technology Press.
