Real time service restoration in distribution networks-a practical approach

This paper presents a methodology for determination of a best set of service restoration strategies for affected load points due to a fault in a distribution network. The method is based on minimum number of switching operations, minimum losses and adherence to the voltage and current constraints. Schemes are also discussed for automatic identification of affected load points and nonrestorable load points. Where restoration is not possible satisfying voltage and current constraints, a scheme for load shedding is also suggested considering priorities of loads
