Abstract
In this paper, Fractional Lévy Flight Bat Algorithm (FLFBA) is used to determine the optimal location of distributed generation (DG) and flexible alternating current transmission system (FACTS) devices in the distribution system (DS). The main objective function considered is to improve the minimum voltage stability index (min VSI) of the DS. Minimum active and reactive power losses are also considered during the analysis of the work. To do this work, Type 1 and Type 2 DGs are considered here. Type 1 DG generates only real power, while Type 2 DG can generate both real and reactive power. To evaluate the efficacy of the proposed technique, it is implemented on standard IEEE 33 distributed test systems (TS). To validate the results obtained by using FLFBA, the same problem is also solved with other optimization algorithms like firefly algorithm (FA), bat algorithm (BA), and particle swarm optimization (PSO) algorithm.
