源网荷储控制系统中储能控制策略的研究和应用

Research and Application of Energy Storage Control Strategy in Source Network Load Storage Control System

大规模储能电站在直流受端电网不断推广建设下,有效拓展了电网故障时的可控资源,降低了电网损耗,提高了电网安全运行水平。储能电站在不同的运行阶段,需要考虑不同的控制策略方案,重点介绍了直流受端电网源网荷精准控制系统中储能电站作为毫秒级紧急控制的可控资源的控制方案和控制策略,对后续策略优化发展的方向进行了展望。

The continuous promotion and construction of large-scale energy storage power stations in the DC receiving end power grid has effectively expanded the controllable resources during power grid failures,reduced power grid losses,and improved the safe operation level of the power grid.Energy storage needs to consider different control strategy schemes at different operating stages.This paper mainly introduces the control strategy scheme of grid energy storage power station at large DC receiving end as a controllable resource for millisecond emergency control,and looks forward to the development direction of the future strategy optimization.
