An Enhanced Rule-Based Approach for Optimizing Energy Costs and Battery Health in Microgrid Systems

Abstract

Renewable energy resource systems have increased significantly as a result of the transition to microgrids. These systems require an effective energy management system (EMS) in order to optimize the flow of energy from the different sources. This paper proposes an enhanced rule-based EMS (EnRB-EMS) for a grid connected photovoltaic (PV)-battery system, in order to optimize the operation of the system to meet the escalating energy demand, minimize the cost of electricity, and increase the battery life by improving the power quality. The proposed strategy is based on a set of real-time information, such as the load demand, the state of charge (SoC) of the battery, and the cost of electricity. The performance of the proposed strategy is evaluated under different scenarios, demonstrating the effectiveness of the proposed strategy in achieving optimal energy management, reducing the electricity cost, and increasing the battery life.
