燃煤发电机组调停调峰成本的公平分摊

Fair allocation of coal-fired unit shutdown cost for peaking in valley time

首先建立了机组中长期调停的优化模型,应用公平分配理论中的无嫉妒性、虚拟价格机制和按责任分摊的原则,分别建立了燃煤发电机组调停调峰成本的无嫉妒性分摊模型、虚拟价格分摊模型和Shapley值分摊模型,并进行了分析比较。应用加总原理解决了不同机组拥有者对公平分配方案的争议。所提模型较好地解决了当前燃煤机组调停调峰成本无法得到补偿以及外来电如何分摊省内机组调停成本等问题。通过浙江电网实际算例,表明本文所提模型能够平衡各方利益,解决当前机组调停的公平效率问题。

An optimal unit commitment model of mid / long term shutdown for peaking is proposed and three cost allocation models of coal-fired unit shutdown for peaking in valley time are established respectively based on ＂no envy＂,virtual price and Shapley value according to the ＂no envy＂ concept,virtual price mechanism and responsibility principle of fair allocation theory,which are analyzed and compared. The aggregation method is applied to treat the controversy of different unit owners over the fair allocation scheme. The proposed models can be used to solve some problems properly,such as the compensation of coal-fired unit shutdown cost for peaking in valley time,the allocation of provincial unit shutdown cost for peaking in valley time to the electricity from outside,etc. With Zhejiang Power Grid as an example,the proposed models can properly balance the benefits of different sides and enhance the fairness and efficiency of unit shutdown for peaking in valley time.
