电力市场环境下发电机组检修规划研究综述

Review of unit maintenance scheduling in market environment

机组停运检修是降低其故障率、确保系统可靠运行的重要措施。电力工业的市场化改革,产生了追求效益最大化的发电厂商和负责系统运行的独立调度机构(ISO)等市场主体,机组检修规划模式应由以系统运行为中心转向在发电厂商的经济效益和系统可靠、经济运行之间取得均衡。围绕机组检修规划问题,从规划模式、应考虑的不确定性因素、检修安排的评判指标、发电厂商的规划模型与ISO的调整策略、模型求解算法等几个方面展开讨论,综述了当前的研究现状,并展望了未来研究应亟需解决的问题。

Unit maintenance scheduling（UMS） is important to reduce the unit failure rate and guarantee the system reliability. The deregulation of power industry creates the independent market entities with different objectives,including the self-interested power producers for maximizing their potential payoffs and the independent system operator（ISO） for ensuring the system reliability. Therefore,UMS should also be determined to achieve a balance between the producers＇ benefits and the system reliability,which is different from the traditional system-centralized mechanism. Based on the current research,this paper mainly discusses the impacts of market environment on the UMS from several aspects,which contain the schedule mode,the related uncertainty factors,the assessment criterion,the producers＇ UMS model and the ISO＇s coordination strategy,and the model＇s solving algorithm. Furthermore,some challenges that may be faced in the future study are also presented.
