Design & implementation of an energy management system

Abstract

This project presents the design, simulation, and implementation of a energy management system (EMS) for micro-grid integrating solar photovoltaic (PV), battery storage, and grid power to ensure a stable and reliable power supply. The system monitors and controls power fl ows based on real-time conditions such as solar generation, battery state of charge (SOC), and load demand. The EMS follows a clear source priority: solar energy is used fi rst, followed by the battery, and fi nally the grid when other sources are insuffi cient. This strategy maximizes the use of renewable energy and minimizes dependence on the grid. Simulation and practical results confi rm that the system operates eff ectively in bothgrid-connected and islanded modes, offering a flexible and scalable solution for modern smart energy needs. The energy management strategy prioritizes the use of renewable sources and enables seamless switching between energy sources to ensure both reliability and efficiency. Simulation and hardware implementation results demonstrate the system’scapability to operate effectively in both grid-connected and islanded modes, providing a scalable and fl exible solution for modern smart energy systems.
