In high renewable energy penetrated power systems, the flexibility of power system resources is indispensable. With the implementation of domestic ancillary service markets, the revenue of ancillary services provided by generating units is gradually changing from the planned mode to the market mode. Moreover, the access threshold for generating units to participate in the ancillary service market has changed. At the same time, the flexibility of generating units has a great impact on the revenue of the ancillary service market. Therefore, this paper summarizes the flexibility requirements of typical pilot areas in China for generating units to participate in ancillary service markets. Then, the corresponding flexibility evaluation indexes of different ancillary services are sorted out and the flexibility evaluation model is developed to evaluate the flexibility ability of power generation enterprises scientifically. The flexibility evaluation system proposed in this paper can effectively evaluate the flexibility capability of generating units and conduct its flexibility enhancement.
