Performance Enhancement of Electrical Distribution Systems with Multiple Distributed Generation Sources

Abstract

The recent trends in electrical power distribution system operationand management are aimed at improving system conditions in order torender good service to the customer. Reforms in the distribution sectorhave given major scope for employment of distributed generation (DG)resources which will boost system performance. This article proposesa heuristic technique for allocation of multiple distribution generationsources in a distribution system. The allocation is determined based onoverall improvement in network performance parameters like reductionin system losses, improvement in voltage stability, improvement in volt-age profile. The hybrid of Genetic Algorithm with the proposed NetworkPerformance Enhancement Index (NPEI) along with the heuristic rulesfacilitates determination of feasible location for insertion of DG sources.A priority list is prepared with decreasing values of NPEI so that thedesigner can select most feasible locations. The developed approach istested with different test systems to ascertain its effectiveness.
