计及电力现货市场竞争效率的输电定价机制量化评价方法

Quantitative Evaluation Method of Transmission Pricing Mechanism Under Circumstance of Electricity Spot Market

我国电力现货市场建设试点工作的不断推进,以及新一轮输配电价监管周期的来临,使得如何选择合理的输电价格机制,使之适应不同地区电力现货市场环境,促进电力现货市场的有效竞争和健康运行成为了亟待解决的问题。该文探讨输电价格机制对电力现货市场竞争效率的影响,提出计及电力现货市场竞争效率的输电定价机制量化评价指标;构建基于"电源投资时序及选址预测模型"和"计及电量输电价格的电力现货市场生产仿真模型"的量化指标计算方法。最后,以我国某省电力系统为例,结合设计的量化评价方法,采用设计实例量化分析电量输电价格对现货市场短期竞争效率的影响,以及系统阻塞情况与现货市场价格形成机制对输电价格机制选择的影响等,为电力现货试点地区的共用网络输电价格机制选择提供参考与借鉴。

As the acceleration of the establishment of electricity spot market pilots and new period of transmission and distribution regulation is around the corner, it becomes a problem needed to be solved urgently that how to choose appropriate transmission pricing method to adapt the electricity spot market and promote the competition in electricity spot market more efficient. In this paper, the influence of transmission price on the efficiency of competition in electricity spot market was discussed firstly, and put forward the quantitative indexes to measure the influence of transmission price on efficiency of competition in electricity spot market. Secondly, the "model of investment sequence and location forecast of power plant" and "model of productive simulation of electricity spot market allowing for energy transmission price" were put forward to calculate the indexes mentioned above. Finally, designing samples which were allowing for the power system of certain province in China to analyze the influence of energy transmission price on the short term efficiency of electricity spot market, and the influence on the selection of transmission pricing method of congestion situation and pricing mechanism of electricity spot market, putting forward suggestions on the selection of transmission pricing methods for the electricity spot market pilots in China.
