    This research presents a comprehensive analysis of an Energy Management System (EMS) implemented in a Microgrid (MG) to optimize power balance modes in three phase inverter system and enhance power quality. Utilizing MATLAB/Simulink software for simulation, the study incorporates a bidirectional DC/DC converter controlled by the EMS algorithm with a Proportional-Integral (PI) loop. The DC-link microgrid integrates a solar (PV) generator, battery storage, and inverter, ensuring efficient power distribution The usual load of the system is 200kW in fixed cases and (100kW to 200kW) in variable load demand cases, and the irradiation is assumed to be from 0W/m2 to 1000W/m2 . The proposed system employs a multi-agent power system to simulate a microgrid and implements a multi-agent system for grid-interconnected stages. By focusing on dissimilar power balance modes and dynamic grid power, the EMS algorithm dynamically adjusts to solar availability, battery state, and grid power. Power balance options are defined based on supply, storage system, and grid mobility, optimizing energy consumption, extending storage life, and delivering reliable power to meet varying load demands. The EMS emphasizes the effectiveness of the two-stage microgrid control system (DC-DC and DC-AC) in control mechanisms with MPPT algorithm, PI controller, bidirectional converter, and seamless transition between power balance modes contribute to an adaptive and efficient microgrid operation.
