Summary:Given the operational characteristics of hydrogen energy storage and the uncertainties in energy sources and loads in hybrid energy storage microgrids, a three-stage multi-timescale hybrid energy storage scheduling strategy is proposed. This strategy incorporates day-ahead, intraday, and rolling-real-time adjustments to optimize microgrid operations and minimize operating costs. The strategy leverages the unique charging and discharging characteristics of hydrogen storage, along with the operational behaviors of battery and flywheel storage systems. Simulation results demonstrate that the proposed strategy effectively optimizes microgrid operations, achieving economic efficiency. Furthermore, the strategy's performance improves significantly in terms of both economy and stability compared to a traditional day-ahead-real-time two-stage scheduling strategy as prediction accuracy decreases. Specifically, at 50% prediction accuracy, the proposed strategy reduces economic costs by 38%.
