通过借鉴国外电力需求侧管理(DSM)脱离机制的成功经验和做法,探讨了适用于我国电网公司的单用户售电收入脱离机制(RPC),该机制将电网公司售电收入与电力用户数目相联系而使售电收入与售电量相脱离,以消除电网公司实施需求侧管理的障碍。文中从实施单用户售电收入脱离机制的前提出发,分析了将电网公司售电收入与电力用户数目相联系的依据与实施该机制所必须解决的现实问题(市场细分以及各细分市场允许收入的确定、将售电成本拆分为资源成本与基本成本),进而建立了该机制的数学模型,模型通过引入电网公司的允许收入这一概念来建立售电收入与电力用户数目之间的联系,从而可通过调整电价来平衡电网公司收入。最后进行了算例分析,算例表明该机制能够很好的调整电网公司允许收入与实际收入的差额,并且简单易行,方便管理。
By referring to the successful experiences and practices of foreign DSM disengagement mechanism, this paper discusses the single-user revenue disengagement mechanism (RPC) applicable to China’s power grid companies. This mechanism compares the sales revenue of power grid companies with the number of power users Contact and sales revenue from electricity sales phase to phase out grid companies to implement demand-side management barriers. Starting from the premise of implementing the mechanism of single-user electricity sales revenue disengagement, this paper analyzes the basis of linking the sales revenue of power grid companies with the number of power users and the realistic problems that must be solved in implementing the mechanism (market segmentation and the allowable Income is determined, the cost of sales is split into resource cost and basic cost), and then a mathematical model of the mechanism is established. The model establishes the relationship between sales revenue and the number of electricity users by introducing the concept of allowable income of grid companies Contact, which can be adjusted by tariffs to balance the company’s revenue. Finally, a case study is carried out. The example shows that the mechanism can adjust the difference between the allowable income and the actual income of the power grid company easily, and is easy to manage.
