A Coordinated Energy Management Control Scheme for a Grid-Integrated PV Hybrid Storage System

Robust energy control has become very essential to maintain the grid stability and power quality as there is rapid rise in the growth of photovoltaic (PV) systems and the increasing dependence on hybrid energy storage This paper proposes an integrated energy management control scheme for a grid-interfaced PV hybrid storage system with battery energy storage and supercapacitors. The multi-layer control strategy proposed here optimises power flow among the PV array, hybrid energy storage, and grid dynamically to efficiently suppress voltage oscillations, frequency deviations, and other power quality issues. Simulation studies under various loads and solar irradiances confirm that the hybrid solution significantly improves both dynamic response and overall system reliability. Such findings substantiate that the hybrid storage solution not only improves power quality but also reduces grid stress and thus is a valuable candidate for advanced PV integration.
