随着电力市场管制的逐步解除,用户获得了选择供应商的机会,并迫切要求供应商能按不同供电可靠性水平进行相对合理的可靠性定价与停电赔偿,以体现公正、公平、公开的市场原则。文中以配电系统为研究对象,提出一种基于用户可靠性需求的综合定价法,有效地弥补了传统单一定价的不足;同时,阐述了建立可靠性赔偿机制的重要性,利用价值分析和配电系统可靠性评估技术推导出用户可靠性赔偿的函数关系,形成适应电力市场运营环境的可靠性电价与赔偿机制。通过对RBTS-BUS6 系统的算例分析表明,该机制可以兼顾供应商和用户的经济利益,实现优质优价、停电赔偿的思想。
With the gradual dissolution of the control of the electricity market, users have been given the opportunity to choose suppliers and urgently require suppliers to conduct relatively reasonable reliability pricing and power outage compensation according to different levels of power supply reliability so as to realize a just, fair and open market in principle. In this paper, the distribution system as the research object, a comprehensive pricing method based on the user reliability requirements is proposed, which effectively makes up for the lack of the traditional single pricing. At the same time, the importance of establishing the reliability compensation mechanism is expounded, The system reliability evaluation technique deduces the functional relationship of user reliability compensation and forms a reliable electricity price and compensation mechanism to adapt to the operation environment of power market. The case study of RBTS-BUS6 system shows that the mechanism can balance the economic interests of suppliers and users, and realize the idea of high-quality and low-cost power supply and power outage compensation.
