Abstract

Abstract: It has been main mode in China that large-scale wind power has centralized into grid, but as the weakness of the grid and a lack of coordination among reactive power compensation devices, the grid loss problem outstands. Regarding to the effect of voltage reduction and reactive power flow on loss, based on characteristics of different reactive power compensation devices, a two-stage coordinated control method was proposed. The method arranged slow discrete capacitors and reactors at long time scale whereas rapid successive static Var compensator(SVC) and static Var generator(SVG) at short time scale. By decomposition and coordination of reactive power compensation devices, it gradually has reached the target of loss reduction. Taking a grid with large-scale wind power integration as the case, the proposed control strategy can achieve a considerable loss reduction result.
