    摘要:

    针对电力现货市场运行后,专项工程输电价格核价电量难以按照原有方法确定,以及现行输电定价机制可能影响电力现货市场竞争效率的问题,提出了面向电力现货市场的专项工程两部制输电价格优化模型。首先分析了中国现行的、以输电功能为主的跨省跨区专项工程输电定价机制在电力现货市场环境下的不适应性,阐述了其在专项工程准许收入回收风险的公平分担,以及在促进电力市场有效竞争等方面产生的不利影响;定性分析了以输电功能为主的专项工程电量输电价格对电力现货市场交易的影响,设计建立了基于一维搜索算法及多时段电能量与备用联合经济调度模型的专项输电工程两部制电价优化模型,以此确定两部制输电价格中通过容量电价回收专项工程准许收入的临界点。通过算例仿真验证了模型的有效性,并分析了影响输电价格结构的关键因素。

    Abstract:

    Aiming at the problem that the pricing energy of inter-provincial dedicated transmission projects cannot be calcu-lated by present method, and the present inter-provincial dedicated transmission pricing method may affect the competition efficiency, putting forward the optimization model of inter-regional dedicated transmission two-part price adapting power spot market. Analyzing the problems faced with the price of China’s inter-regional/provincial dedicated transmission projects, elaborating the negative influence by using traditional postage stamp method in the risk allocation of cost recovery, and promoting the efficient competition in electricity spot market. By using power market simulation tools, analyzing the influence of inter-regional transmission price structure and form in the transaction in power spot market. Establishing optimization model of dedicated transmission two-part price based on One-dimensional search and joint economic dispatching model of energy and power reserve, determining the critical point of the two-part transmission price. Combined with the case analysis, proving the effectiveness of the model, ,and analyzing the key factors affect the form and structure of the price.
