【摘要】：近年来我国经济快速发展,能源资源分布和各地能源需求的不均衡问题日益突出,迫切需要建立高效、可靠的能源运输系统。电网是一种高效、便捷的能源运输途径,能够把一次能源转化成的电能,经济地、快速地传送到负荷中心。方面电网投资巨大需要有科学、合理的输电定价方法保证电网公司投资成本的回收；另一方面目前我国没有独立的输电定价体系,输电价格不能真实的反映输电成本,难以起到反映供需关系、引导资源优化配置的作用。因此在输配分离的大背景下,研究独立的输电定价方法对于保障我国国民经济的可持续发展和推动电力市场的深化改革意义重大。 本文首先对现有的输电定价方法和国内外实践进行了综述分析,利用福利经济学比较了各种电价结构的优缺点和适用性,对现有的基于边际成本和综合会计成本的两大类输电定价方法进行了总结,并比较了各种输电定价方法的优缺点。 在国内外输电服务价格理论与实践的基础上,针对我国跨省跨区输电通道利用率较低的问题,本文提出了输电服务峰谷分时定价方法,通过计算典型日24时刻输电通道可用传输容量的变化情况,利用隶属度函数将每天划分为高峰、平段、低谷三个时段,求解非线性规划问题优化峰谷输电价格比,在不同的时段设定不同的输电价格,从而反映不同时间段的供需关系,引导用户合理的使用输电网络资源,达到资源的优化配置。 最后以IEEE30节点算例验证了模型的合理性,算例分析表明,输电服务峰谷分时定价方法能够较好地提供价格信号和提高输电通道的利用率。
[Abstract]:In recent years, with the rapid development of economy in China, the distribution of energy resources and the imbalance of energy demand are becoming more and more serious. It is urgent to establish an efficient and reliable energy transportation system. Power grid is an efficient and convenient way to transport energy. It can transfer primary energy to load center economically and quickly. On the other hand, there is no independent transmission pricing system in our country at present, and transmission price can not truly reflect transmission cost. It is difficult to reflect the relationship between supply and demand and guide the optimal allocation of resources. Therefore, under the background of separation of transmission and distribution, it is of great significance to study the independent transmission pricing method to ensure the sustainable development of our national economy and to promote the deepening reform of the electricity market. This paper firstly summarizes and analyzes the existing transmission pricing methods and domestic and foreign practices, and compares the advantages and disadvantages and applicability of various price structures with welfare economics. This paper summarizes the two kinds of transmission pricing methods based on marginal cost and comprehensive accounting cost, and compares the advantages and disadvantages of the various transmission pricing methods. Based on the theory and practice of transmission service price at home and abroad, a time-sharing pricing method for transmission service peak and valley is proposed to solve the problem of low utilization rate of transmission channels across provinces and regions in China. By calculating the change of available transmission capacity of typical transmission channels at 24 hours a day, the daily transmission price ratio is optimized by using membership function, which is divided into three periods: peak, flat and low, to solve the nonlinear programming problem. Different transmission prices are set in different time periods, which reflect the relationship between supply and demand in different time periods, guide users to use transmission network resources reasonably, and achieve optimal allocation of resources. Finally, the rationality of the model is verified by the example of IEEE30 node. The analysis of example shows that the time-sharing pricing method of transmission service peak and valley can provide price signal and improve the utilization of transmission channel.
