Joint power generation schedules of wind farms and pumped storage power stations based on load tracking

摘要

Joint power generation of wind farms and a pumped storage power station is an important way to improve reliability for wind power paralleling in power grids. Based on load tracking, joint power generation schedules of wind farms and pumped storage power stations are researched. Two kinds of joint power generation schedules are put forward including fluctuation tracking mode and constant tracking mode. In order to analyze them, generation reliability index is set up, considering maximal output and generation schedule power of wind farms and pumped storage plants joint generation. The index can quantify generation reliability, by which proposed schedules are compared. Two kinds of proposed generation schedules are analyzed by an example. The results show that constant tracking generation schedule is better than fluctuation tracking generation schedule.
