摘要

Because electricity cannot be stored, in order to guarantee the security and the reliability of power system, the frequency and the voltage must be kept in a reasonable range and the supply and the demand of active power and reactive power must keep real-time balance. Under the new competitive environment of the electricity market, from angles of technology and economy, people increasingly pay more attention to the market-oriented operation of ancillary service market (ASM) in order to guarantee the network to run economically and reliably. From the market mode, the exchange manner, pricing mechanism, and the dispatching manner, this paper does research on the international comparing of the market-oriented operation of ASM. At the same time, combining the situation of China, this paper discusses some problems about market mode and exchange manner of ASM and provides rational suggestion to our country's market-oriented operation of ASM.
