MVO Algorithm for Optimal Simultaneous Integration of DG and DSTATCOM in Standard Radial Distribution Systems Based on Technical-Economic Indices

Distributed Generation (DG) involving clean renewable energy resources and power electronic devices for control have been the main focus of researchers in electrical power engineering nowadays. The paper presents a new technique for obtaining the best locations and ratings of the DG units, which are based on photovoltaic solar panels, and the Distribution Static Compensator (DSTATCOM), in Radial Distribution Systems (RDSs). The objective function deployed is subject to equality and inequality constraints and aims to minimize three technical-economic system indices, which are Apparent Power Loss (APL), Total Voltage Variation (TVV), and Annual Losses Cost (ALC). Multi-Verse Optimizer (MVO) is a recently developed nature-inspired algorithm, which is utilized to obtain the optimal integration of DG and DSTATCOM into the system. In this paper, four case studies are considered, which involve the base-case, the individual deployment of either DG or DSTATCOM, and the simultaneous deployment of DG and DSTATCOM to test the system performance, while using the MVO algorithm. To verify its validity, the algorithm is tested on the standard IEEE 33- and 69-bus RDSs whose results are compared with the results obtained when using other existing algorithms. Comparison among results reflects the strength and suitability of the suggested MVO algorithm in minimizing the real power losses and enhancing the voltage profile.
