A Unit Maintenance Scheduling Model Considering Peak Regulation Pressure Balance for Power System Containing Wind Farms
摘要
Abstract
Grid-connection of large-scale wind power system brings new challenge to peak regulation of power grid and the maintenance outage of wind power generators has a certain effect on peak regulation ability of power grid. Along with the increase of the scale of grid-connected wind farm the coordination of power grid peak regulation ability should be considered in unit maintenance scheduling. A medium- and long-term unit maintenance scheduling, in which the economy of maintenance, reliability and balance of peak regulation pressure is synthetically taken into account, is proposed for power grid containing wind farms. Combining with the influence of grid-connected wind farms on peak regulation of power grid and peak regulation ability of different types of units, an index to measure peak regulation pressure for power grid containing wind power systems is proposed. On this basis, a method to balance the peak regulation pressure in maintenance scheduling is researched. According to different peak regulation abilities of units and the intensity of peak regulation pressure in different time intervals the unit maintenance is reasonably scheduled to balance peak regulation pressure of power grid; the constraint of maximum peak regulation of power grid is added in constraint conditions to ensure that after the maintenance scheduling is drafted the peak regulation pressure of power grid can be kept to a reasonable level. The proposed model is solved by genetic algorithm. The availability of the proposed model is verified by results of calculation example.关键词
