The rise in renewable energy resource (RES) consumption has prompted academics to maximize RES performance. Many studies address the optimal placement of photovoltaic (PV) units and DSTATCOM units, as well as reconfiguration hurdles, by specifying the number of PV units used in the simulation. Optimization alone cannot improve power system operational efficiency without considering the microgrid's PV unit count. Hence, the objective of this work is to address multi-objective problems in the context of modifying radial distribution systems to operate as a microgrid (MG), with the aim of ensuring the microgrid's security and stability while achieving optimal performance. In this paper, the Firefly algorithm (FA), an optimization technique, is used to determine the size, location, and DSTATCOM within specified ranges to determine the number of PV units to install and the open network lines. The Twain 84-bus system was employed to assess the suggested method's accuracy and efficacy. The outcomes amply illustrated the approach's superiority and efficacy in enhancing MG performance. The proposed method addresses PV unit installation and DSTATCOM installation and reconfiguration in the MG. Also, it enhances the voltage profile and reduces losses of both reactive and active power.
