Microgrid energy management with renewable energy using gravitational search algorithm

Abstract

The microgrid energy management with renewable energy is efficiently integrating intermittent sources like solar and wind while ensuring grid stability and reliability is difficult. The gravitational sear search method is employed in MG energy management with renewable energy sources (RESs) to address these problems. The gravitational search technique is used in the proposed method (GSA). In order to build a database of control signals that take into account the power differential between the source and load sides, GSA is used to precisely identify the control signals for the system. The proposed technique’s main goal is to deliver the best performance at the lowest possible cost. The constraints are the availability of the RESs, energy consumption as well as the storage elements’ level of charge. Batteries are utilized as an energy source to steady and allow the renewable power system components to continue operating at a constant and stable output power. The proposed method cost is 1.1$ that is lower than the existing methods. The MATLAB platform is used to implement the proposed method, and its efficacy is assessed in comparison to established techniques like modified PSO (MPSO), genetic algorithm (GA), particle swarm optimization (PSO), and proportional integral controller (PI) (MPSO).
