针对利用储能提高风电对其并网系统的友好性，给出了一种基于储能平抑风电出力波动的策略。对大规模风电并网的某区域电网负荷与风电出力的数据进行了统计分析，得到负荷和风电出力的时域分布规律，提出了利用储能系统协调风电场有功出力与其并网系统负荷功率波动的策略，并建立了相应的数学模型。基于电力系统分析软件 DIgSILENT-POWER FACTORY13.1进行了仿真验证，结果表明利用储能改善后的风电有功出力，能够追踪负荷曲线的变化规律，并网风储合成出力对电力系统可以起到“削峰填谷”作用，储能以较低的成本提高了风电对其并网系统的友好性。

Aiming at using the energy storage to improve the friendliness of wind power to its grid system, a strategy based on energy storage to stabilize the wind power output fluctuations is given. A regional power grid load and wind power output data of large-scale wind power grid are counted and analyzed, the time-domain distribution law of load and wind power output is obtained, the strategy using energy storage to coordinate active power output of the wind farm and load power fluctuations of its power grid system is proposed, and the corresponding mathematical model is established. The simulation is made based on the power system analysis software DIgSILENT-POWERFACTORY13.1. The results show that the modified active power output of wind power through using energy storage can track the load curve variation, the synthesizer output of grid-connected wind power energy storage on the power system can play the role of“load shifting”, and energy storage improves the friendliness of wind power to its grid system at a lower cost.
