Optimal Planning of DGs in Radial Distribution System Using Many-Objective Arithmetic Optimization Algorithm and Multi-Criterion Decision-Making TOPSIS Approaches

This paper presents an optimal DG planning method using a Pareto-based Many-Objective Arithmetic Optimization Algorithm (MOAOA) to improve four technical metrics of the distribution system: mitigation of Electrical Energy Not Served (EENS), total voltage deviation minimization, enhancement of voltage stability index, and energy loss curtailment. The method is tested on a standard IEEE-33 bus distribution system and compared with other methods like MOPSO, MOGWO, and NSGAII. The study aims to address the challenges of improper DG integration in distribution networks.
