摘要
交流联网可能会带来互联电网的动态稳定性问题。通过对交流和直流2种联网方式的对比分析,提出利用储能技术实现交流互联电网分区解耦控制的思路,即通过储能装置消除2个交流互联的区域电网之间的相互影响,各区域电网只需按照本区域的电网特性进行稳定控制。
The dynamic stability of the interconnection grids would be affected by AC interconnection. By comparisons between the AC and DC interconnection, this paper proposed a method by which the region decoupling control for AC interconnected girds could be achieved by using energy storage technology, that is, the stability control of the region gird could be implemented just according to its own characteristic, by that the energy storage device eliminates the mutual influence between the interconnected girds. The feasibility of the region decoupling control was proved by theoretical analysis. The influence of the energy storage device position on the proposed control and the capacity requirement of the energy storage devices were discussed. The practical control strategy was proposed. Its validity was verified by simulations in ~wo power systems.
