两种可供实用的发电侧电力市场竞价交易模式

TWO BIDDING MODES OF GENERATION-SIDE ELECTRICITY MARKET FOR APPLICATION

针对我国电力体制改革进程中的实际情况和发电侧电力市场的发展趋势,对现有发电侧竞价交易模式进行了比较分析。结合我国国民经济发展的实际情况和电网经济调度的特点,提出了两种可供实用的发电侧电力市场竞价交易模式:一种是基于仅由固定成本确定容量电价而提出的“容量合同+全电量竞价+适时市场”模式;另一种是基于由固定成本和变动成本之和确定客量电价而提出的“容量合同+效率置换+适时市场”模式。经系统仿真和实际试运营,所提出的两种模式都是切实可行的。这两种模式有利于实现资源的优化配置、降低发电总成本、降低用户电价、促进我国工农业生产的快速发展。

Considering the actual situation of power system innovation and the development trend of generation-side electricity market in China, the existing bidding modes are analyzed and compared in this paper, and two new applied bidding modes of generation-side electricity market are introduced, which closely combine the actual situation of national economy and the operation characteristics of power grid in China. One is called 'capacity contract plus whole power quantity bidding and timely market', in which the capacity price is only determined by fixed cost. The other is called 'capacity contract plus efficiency exchange and timely market', in which the capacity price is confirmed by the sum of fixed cost and variable cost. System simulation and actual application test prove the reliability and feasibility of these two modes, which are propitious to achieve the optimal resource arrangement and the reduction of total generation cost, and the decrease in the consumer's price as well, thus promotes the rapid development of industry and agriculture.
