Hybrid Optimization Technique for Optimal Placement of DG and D-STATCOM in Distribution Networks

Abstract:

This paper proposes a hybrid analytical and metaheuristic optimization technique to find the proper locations and sizes for the distributed generator (DG) and Distribution Static Synchronous Compensator (D-STATCOM) in distribution networks to minimize the total losses. The analytical technique may be unsuitable to give the best place and capacity of DGs and D-STATCOMs. In this work, a combination between the analytical based on voltage stability index (VSI) and sine-cosine algorithm (SCA) is developed to achieve a minimum loss and regulate the distribution system voltage. In the proposed technique, the optimal location is selected using the VSI while the optimum capacities for the DG and D-STATCOM at each bus are evaluated using the SCA. The proposed hybrid optimization approach is comprehensively compared with other existing analytical and metaheuristic optimization techniques to prove its effectiveness. All simulations are executed using the standard IEEE-12 and 69 bus radial feeders on MATLAB M. Files.
