A Multi Objective PSO Algorithm for Sizing and Allocation of Dg's from Dg Owner's and Disco's View Points

This novel presents multi objective approach for calculating the DG optimum allocation, sizing and contract price simultaneously. DG’s (distributed generation) have significant benefits in the electric power industry, such as improvement of voltage profile in distribution feeders , amending voltage stability heavy load levels , enhancement of reliability and power quality ,as well as securing power market. Despite the numerous advantages of DG’s technologies, weak capability in dispatching and managing of DG’s is a major challenge for distribution system operators. This novel presents a application of multi objective particle swarm optimization with the aim of determining the optimal DG allocation and sizes and their generated power contract price .The proposed multi objective optimization algorithm determines , not only the operational aspects (such as improving voltage profile and stability , power loss reduction ) and also reliability enhancement taken into account , and an economic analysis is performed based on distribution companies and DG’s owners viewpoints. This paper explained IEEE 33 bus distribution test system and the consequent discussions proven the effectiveness of the proposed approach.
