摘　　要： 直接负荷控制(DLC)是电力市场下需求响应的重要手段之一。作为一种灵活的激励机制,设计合理的DLC实施机制并对其进行优化决策是其成功的关键。文中在分析电力市场下DLC实施过程的基础上,将DLC应用于供电商购售电风险管理,并探讨了供电商实施DLC的效益。利用模糊隶属度函数来反映用户的综合满意度,并提出了DLC调度的公平性指标。由此建立了兼顾供电商和用户利益的多目标DLC优化决策模型,并利用非支配排序遗传算法进行了求解。最后通过算例仿真验证了所述方法的有效性,它有利于保证DLC各参与方的利益,实现多方共赢。 Direct load control （DLC） is an important measure of demand response in electricity markets. As a flexible incentive mechanism,designing rational DLC implementation strategy and optimizing DLC decision are crucial to its successful implementation. Based on the analysis of DLC implementation process,DLC is applied to electricity purchasing and selling risk management for power suppliers and the benefits of implementing DLC for power suppliers are explored. Fuzzy membership functions are adopted to reflect customer composite satisfaction of participating DLC and the equity index of DLC schedule is presented. Furthermore,a multi-objective DLC decision model which considers the benefits of both power supplier and customers is introduced and then solved by non-dominated sorting genetic algorithm II. Numerical results are finally used to prove the effectiveness of the proposed model,which is beneficial to ensuring multi-faceted interests and realizing multi-party win.
