According to the abstract released by the Intellectual Property India: "This work presents an adaptive energy storage control system for smart microgrids that coordinates forecasting, state estimation, multi-timescale decision-making, and battery health-aware dispatch. The proposed framework integrates a supervisory energy management layer, a predictive optimization layer, and a fast local control layer to regulate battery charging and discharging, support frequency and voltage stability, reduce operating cost, and improve renewable energy utilization. A hybrid AC/DC microgrid operating in both grid-connected and islanded modes is considered, including photovoltaic generation, wind generation, controllable loads, a lithium-ion battery energy storage system, and the utility grid. The control objective jointly minimizes operating cost, battery degradation, unserved energy, renewable curtailment, and deviations from nominal operating limits. A receding-horizon optimization strategy with adaptive rule updates is employed to address load uncertainty, renewable variability, and battery state-of-health changes. Simulation studies under normal operation, peak shaving, outage ride-through, and uncertainty stress conditions show that the proposed method achieves lower energy purchase cost, smoother battery power response, reduced frequency deviation, improved renewable hosting capability, and enhanced islanded survivability compared with conventional baseline strategies."
