电力市场环境下发电机组检修计划的安排与传统电力工业运行管理体制下有很大的不同。由系统调度机构统一安排发电机组的检修计划与电力市场机制并不吻合,而由发电公司自主确定其所拥有的发电机组的检修计划则可能会对系统的安全可靠运行构成威胁。因此,研究适当的市场机制,在必要时对发电公司申报的检修计划进行调整以确保系统安全可靠运行,同时保证对所有的发电公司公平,是一个亟待解决的重要问题。文中对系统运行机构(如ISO)调整发电公司申报的机组检修计划的机制进行了较系统的研究。所提出的机制通过引入发电公司对维持其所申报的检修计划不被ISO调整的意愿支付(willingness—to pay),可以同时保证系统的安全可靠性和发电公司间的公平性,易于被发电公司接受。最后用一个算例说明了该方法的基本特征。
The arrangement of the maintenance plan of generator set in the electricity market environment is quite different from that of the traditional power industry operation and management system. It is not in conformity with the electricity market mechanism that the system dispatcher arranges the maintenance of the generator set uniformly. However, the maintenance plan of the generator set owned by the power generation company itself may pose a threat to the safe and reliable operation of the system. Therefore, it is an important issue that urgently needs to be solved to study proper market mechanism and adjust the maintenance plan declared by power generation companies when necessary to ensure the safe and reliable operation of the system, and to ensure fairness to all power generation companies. The paper systematically studies the mechanism of adjusting the unit maintenance plan declared by the power generation company by the system operating mechanism (such as ISO). The proposed mechanism, by introducing a power generation company willingness-to-pay to maintain its declared maintenance plan not subject to ISO adjustment, can at the same time ensure the safety and reliability of the system and the fairness between the power generation companies and is easily met by the power generation company accept. Finally, an example is given to illustrate the basic characteristics of this method.
