摘要
高比例分布式电源的接入加剧电网电压波动、电压越限等问题,城市电网电缆使用率增加,也使得有功和无功功率均对电压造成影响。首先,概述了储能有功/无功电压控制技术,评述了电网中储能协同无功补偿设备及柔性清洁能源的电压控制策略。其次,总结了储能、无功补偿设备及柔性清洁能源的协同规划模型和优化求解算法。最后,结合储能参与电网调压的研究现状,归纳目前研究所面临的难点,并展望未来电网电压控制新趋势。
The access of high-proportion distributed power sources has aggravated the problems of grid voltage fluctuation and voltage over-limit.The increase of cable usage rate in urban power grids has affected both active and reactive power.Firstly,the energy storage active and reactive power coordination voltage control technology based on PQ decoupling is summarized.The voltage regulation strategy of energy storage synergistic reactive power compensation equipment and flexible clean energy in power grid is reviewed.Secondly,the model and optimization algorithm of energy storage,reactive power compensation equipment and flexible clean energy are summarized.Finally,combined with energy storage to participate in the status quo of power grid regulation,it summarizes the challenges faced by the current research and looks forward to the new trend of grid voltage control in the future.
