Abstract

Effective recovery strategy can reduce largely load-loss after the fault of power distribution network and improve the power supply reliability.In this paper

a two-stage optimization model of recovery control of the power distribution network is set up to obtain maximum economic benefit.Considering uncertainty of DG output and load requirement

the model is improved and optimized on the base of scenario generation and reduction method so to improve the robustness of the recovery strategy and

moreover

the function relationship of multiple variables between load and DG fluctuation magnitude and fault recovery economic loss.The 44-node test system is set up and the effectiveness of the proposed method is verified by the Matlab simulation.
