Abstract:The new type power system with wind and solar generations as the main power generation resources is constructed accelerately in china. In order to maintain stable operation of power system, ensure the power quality, and promote the consumption of clean energy, it is necessary for all kinds of market participants to provide more abundant and diversified ancillary services. In this paper the new type power system ancillary services are classified into firstly three categories, namely, “clean consumption AS”, “power quality AS” and “security and stability AS”. Then, it describes the characteristics and difficulties of the market acquisition and articulation mechanisms of different ancillary services, and then analyses the sharing and compensation mechanisms of ancillary services. Finally, the future research directions of the market-based acquisition mechanism of ancillary services are prospected.
