Abstract: Pump-storage capacity optimization is very important to improve wind farm operation economics. According to wind farm characteristics, an operation strategy of wind power-pumped storage system is proposed to reduce effect of wind fluctuations and randomness on system stability. A model is proposed to calculate reference value of wind farm output power, which is used by dispatcher to formulate generation plans. A stochastic optimization model for determining pumped-storage capacity is presented, which aims to minimize total cost of wind farm operation and pumped-storage installation and maintenance. The model is solved by chaotic particle swarm optimization algorithm. Analysis of examples show the effectiveness of proposed scheduling strategy.

Key words: wind farm, pumped-storage power station, capacity optimization, stochastic programming, chaotic particle swarm optimization algorithm
