FAST SERVICE RESTORATION FOR LARGE-SCALE DISTRIBUTION-SYSTEMS WITH PRIORITY CUSTOMERS AND CONSTRAINTS

A fast, effective service restoration method is designed for large-sca le distribution systems with priority customers. The service restorati on problem is formulated as a constrained multi-objective optimization problem. A ranking-based search method employing analytical informati on obtained from three-phase power flow simulations is designed to res tore service to as many priority customers as possible while maximizin g the amount of total load restored and minimizing the number of requi red switch operations. The proposed method is designed with considerat ion to networks which have predominantly manual switches. Comprehensiv e simulation results of the search method, including priority customer s, single and multiple faults and multiple out-of-service;areas are pr esented for a 416 bus distribution network.
