A grey-based approach for distribution network reconfiguration

This work presents a new concept for selecting restoration plans in power distribution systems using the Grey Relational Analysis (GRA) and the Analytical Hierarchy Process (AHP) approach. The GRA is used to analyze the preference ranking of each restoration plan, and the AHP is adopted to deal with assessing the weighting values of each objective function in a rational way. The proposed decision analysis framework can be applied to assist distribution system operators to make right decisions during a power system restoration process. The effectiveness of the proposed method is demonstrated through a numerical example. The test results show that the proposed method can rank each restoration plan in a quantitative way and obtain a preferable restoration plan correctly.
