A fuzzy reasoning approach for distribution automation

A new approach based on fuzzy reasoning is proposed for electricity service restoration in a distribution system following a fault to minimise the out-of-service time in the out-of-service area with no overloaded components. An emergency heuristic restoration plan was determined to restore the electricity service. A proper short and long term restoration plan using the typical hourly load patterns and real-time metering of the loads is proposed in order to reach the electricity service with minimum out-of-service time. A service restoration on the ENEL distribution system is considered to illustrate the potentials of the suggested fuzzy reasoning approach. The procedure can be easily integrated in the existing distribution dispatching centre with a normal PC.
