　　为解决风力发电和光伏发电等间歇式电源输出功率波动引起的电网电能质量下降问题，提出了利用储能系统来提高间歇式电源并网点的功率稳定性以及改善电能质量。采用间接组合建模的方法建立基于PSCAD/EMTDC的典型风力发电、光伏发电和蓄电池储能的单元模型，并在此基础上构建风电/储能、光伏/储能、风电/光伏/储能系统，并进行仿真和电能质量分析。系统仿真结果表明：储能系统能有效改善间歇式电源功率输出的稳定性和电能质量。

To solve the problem of voltage fluctuation and compromised power supply caused by the unsteady wind turbine and photovoltaic power output, we propose using the energy storage systems to improve stability of the power output and the power quality of the grid-network. The indirect combination modeling method is employed to establish the models of typical wind generator, photovoltaic generation and battery energy storage by PSCAD/EMTDC, based on which the Wind-Battery generation system model, solar-battery generation system model and wind-solar-battery hybrid generation system model in grid-connection are built. The simulations show that the power stability and the quality of the intermittent energy output can be improved using the proposed method.
