Optimal Placement of DG and Minimization of Power Loss using Naked Mole Rat Algorithm

Electrical energy is necessary for daily operations. The promotion of producing electrical power from renewable energy sources like wind, tidal waves, and solar energy is due to the significant relevance of all potential energy sources from which it may be generated. As a consequence of the recent increase in interest in renewable energy sources, there have been a sizable number of studies on integrating distributed production into the electrical grid. The main objective of adding DG units to the network is to deliver a net amount of energy while reducing power losses. To reduce the distribution system's power losses, it is essential to determine the required ratings and best placements for local generations. Much research has been carried out to establish the best place for DG installation. This research study deals with the new algorithm, called the Naked Mole-Rat Algorithm (NMRA), to evaluate the required ratings and best locations of Distributed Generation (DG) units in a radial distribution system, considering minimum power losses and improvements in the voltage profile. In this work, the placement of DG units is found using a fuzzy method, and the size of DG is estimated using a Naked Mole-Rat algorithm. The proposed approach was developed in MATLAB, and after being evaluated on test systems with 15-bus and 33-bus, the results were provided.
