Assessment of Deployment of DGs and D-STATCOMs in Distribution Network using Gravitational Search Algorithm

Abstract

The assessment of distribution network (DN) for reduce the losses and improve power quality, obtaining precise allocation of distributed generation (DG) and distribution static synchronous compensator (D-STATCOM) is mandatory in DN. This paper shows DN analysis with allocation of DG and D-STATCOM for various cases. The nature inspired metaheuristic method, the Gravitational Search Algorithm (GSA) is proposed to obtain the precise allocation of DG and D-STATCOM individually and simultaneously in DN for power losses reduction and total annual energy saving for distribution network operator. To check the performance of algorithm, it is tested on IEEE 33 and IEEE 69 buses DN for various positions of DG and D-STATCOM in DN. The proposed algorithm's performance is compared by some existing algorithms. It is found that proposed technique is able to reduce losses and annual energy saving in distribution network.
