This paper presents a novel reinforcement learning (RL)-based methodology for optimizing microgrid energy management. Specifically, we propose an RL agent that learns optimal energy trading and storage policies by leveraging historical data on energy production, consumption, and. . In this paper it is shown that control of generated power is achieved from the microgrid (MG) to cater the sensitive and critical load during disturbances. The effect of RL load connection and disconnection is shown by MATLAB results. The converter used is a voltage source inverter (VSI) which is. . Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms. A unique reactive power planning approach has been developed in this work by using the modified version of Newton–Raphson approach to identify the weak buses in a microgrid which need the immediate. . The microgrid (MG) ensures a reliable power supply as it can work in a grid-independent mode. One major challenge in a grid-independent MG is the reactive power-sharing issue. Specifically, we propose an RL agent that learns. . The effective management of reactive power plays a vital role in the operation of power systems, impacting voltage stability, power quality, and energy transmission efficiency.
