Effectiveness Assessment of Black Start Schemes Based on Data Envelopment Analysis from the Perspective of Power Grid Crisis

Abstract

Black start of power system is an issue of typical semi-structural optimization. Black-start scheme of power-grid recovery should have one or more alternative plans, when one project due to some special links cannot be successfully implemented, the other can quickly be implemented, so as to ensure the success rate of black-start crisis recovery. The preplan of crisis management requires the effective plan of crisis disposal, especially the preplan of black-start-path must be established, because effective recovery-path program can obtain an effective disposal of crisis to prevent the spread of the crisis. It is by the model of DEA that can evaluate the relative efficiency of the same type of black-start-path with multiple input, multiple output indexes, so as to identify gaps and improve the factors that affect the efficiency. So we chose the DEA model to evaluate the selection-path of black-start.
