Optimal Integration of DSTATCOM and Distributed Generation in the Distribution System using FLFBA

Abstract

In this paper, optimal allocation of DSTATCOM and distributed generation (DG) are determined for distribution system (DS) using Fractional Lévy Flight Bat Algorithm (FLFBA). To do this work, improvement of the minimum voltage stability index (min VSI) in a DS is considered as an objective function. At the time of analysis of this work, minimum active and reactive power losses are also considered. Two types of DG i.e. Type 1 DG which generates only real power and Type 2 DG, which generates both real and reactive power are used in this work. To evaluate the usefulness of the proposed techniques, it is implemented on the test system of IEEE 69 bus DS. The work is also solved with other meta-heuristic optimization algorithms likes bat algorithm (BA), firefly algorithm (FA), and particle swarm optimization (PSO) algorithms. To validate the implemented approach, the results obtained from these three algorithms are compared with the results of FLFBA.
