摘要
针对风电功率随机性、波动性以及不确定性对电力系统安全稳定运行的影响,风电功率预测误差使大规模风电并网难度增大的现状,根据储能系统具有响应速度快及对能量进行时空平移的特点,在分析风电功率预测误差分布规律的基础上,对储能系统类型的选择、补偿控制策略设计、储能系统功率容量配置等研究成果及发展现状进行了综述,并对未来应用储能系统补偿风电功率预测误差等多方面的关键技术进行了展望。
The characteristics of wind power's randomness,volatility and uncertainty make great challenges to the stable operation of power system.The existence of wind power forecast error increases the difficulty of power grid connection.According to the energy storage system has the specialty of fast response and space-time shift of energy,based on the analysis of wind power prediction error distribution law,this work summarizes the application research results and development status of energy storage system type selection,compensation control strategy design,energy storage system power capacity allocation and so on.The key technologies of the energy storage system to compensate wind power forecast errors in the future are prospected.
