摘　　要：储能技术在提高间歇式电源可控性和可靠性,提升其接入友好性方面具有广阔的应用前景。然而分散独立控制风储系统的无序充放电可能带来更多的不确定性,不利于电网的安全经济运行。针对集群风储系统,构建了本地风储系统、集群控制中心以及电网调度中心广域协调互动的基本框架。提出基于超短期风功率预测的本地风储系统优化控制策略以及集群风储系统广域协调控制方法。通过仿真分析可知,提出的控制策略可充分利用集群风电出力的时空差异性,有效提高储能的利用效率,增强集群风电出力的整体可控性。Energy storage technology has great potential in improving the integration friendliness of intermittent renewable sources by enhancing their controllability and reliability. However, the disordered charge-discharge of independent and decentralized control energy storage systems（ESS） may bring more uncertain problems, which have negative impacts on economic operation of power system. A wide-area coordinated control framework, containing local wind-ESS plants, cluster control center and grid center, was designed for cluster wind-ESS integrated system. Based on ultra-short wind power prediction, the optimal control strategy for local wind-ESS and the wide-area coordinated control method for cluster wind-ESS were proposed. Simulation results indicate that the proposed control strategy can make full use of the spatial and time difference of wind-ESS integrated systems, and greatly improve the ESS efficiency and the overall controllability of the system.
