Abstract

The authority of unit maintenance scheduling belongs to PX and not to each generate company in China electricity market. It is a considerable problem for PX to make maintenance scheduling to play fair, to balance the declaring demand between generate companies and to undertake the reliability of grid. The benefit bodies classify into n+2 kinds: n generate companies, the grid company and "society". According to this analysis, the maintenance scheduling model is represented as multi-objective optimum problem. The objects are so much that the mathematics solution is difficult. If weighting average method is adapted to shift these to single object, the physical meaning of the weighting is not clear. On the basis of analyzing the gain and loss of all economic entities, n+2 objective functions are changed to 2 objective functions and weighting average method is adapted to realize the single objective function optimum. The physical meaning of the weighting is explained as the compromise between the efficiency and fair.
