Economic intelligent control mechanism of multi-energy complementary microgrids

To address the challenges of renewable energy integration and power grid stability, this paper presents a multi-energy complementary microgrid system incorporating photovoltaics (PV), wind energy, hydrogen storage, and battery energy storage. By designing a central power control strategy based on real-time electricity prices and hydrogen storage status, the system achieves economical intelligent switching across 12 typical operating conditions. We construct a detailed simulation model using the MATLAB/Simulink platform to thoroughly analyze power flow, energy storage status, and bus voltage characteristics under different energy supply-demand scenarios. The results demonstrate that the proposed control mechanism can enhance the utilization rate of renewable energy to 92% and improve economic benefits during electricity price fluctuations, providing theoretical support for the low-carbon transformation of new power systems.
