Research on Market-Oriented Arrangement Method of Generation Unit Maintenance for Power System Based on Generation Quotation

A market-oriented arrangement method of generation unit maintenance for power system based on generation quotation has been proposed in this paper. There are four parts of the overall scheme of the method, namely generation quotation, maintenance market clearing, check of power balance and settlement of maintenance cost. The method comprehensively considers the maintenance intention of generation unit by constructing the maintenance clearing model which is a mixed integer programming model. And the model can be solved by a general solver easily, which means that it can be applied to a complex large-scale systems. The power supply is sufficiently considered and it effectively ensures the safety of system operation. And also, the maintenance payment cost and return cost fully relate the clearing result to the economic benefit, which ensures the fairness of the clearing model. The market-oriented maintenance arrangement will reflect the willingness of generation unit from the perspective of economy, so as to maximize the use of existing resources. It is also proved that by applying the above process, the market-oriented arrangement and related costs of maintenance can be obtained fairly.
