摘要
基于风电场及抽水蓄能电站的运行特性,建立了考虑输出波动的风电-抽水蓄能联合优化运行的模型。以风电-抽水蓄能联合体输出功率最平滑为目标,引入上水库库容日循环约束和抽水蓄能机组最大启停次数约束。基于风电场4种典型风电参数设计了算例系统,采用改进的粒子群算法进行优化求解,仿真结果表明:风电场与抽水蓄能电站联合运行不但能够降低风电波动性对电网运行的影响,提高电网消纳风电的能力,而且还能够对联合输出功率起到平滑作用。
Based on the operation characteristics of wind farm and pumped storage power station, a model of combined optimal operation of wind power and pumped storage considering output fluctuation is established. Taking the wind power-pumped storage complex with the smoothest output power as the goal, the restriction of the daily capacity of the upper reservoir and the maximum number of start-stop times of pumped storage unit are introduced. The improved Particle Swarm Optimization (PSO) is used to optimize the solution. Based on the four typical wind power parameters of wind farm, an example system is designed. Simulation results indicate that: the joint operation of wind farm and pumped storage power station can not only reduce the impact of wind power fluctuation on power grid operation or improve the ability of power grid to absorb wind power, but also smooth the joint output power.
