Research on Multi-modal Wind-solar Coupling Hydrogen Production Intra-day Energy Management Strategy

To address the issue of unreasonable energy allocation in wind solar hydrogen storage hybrid power generation systems, this paper proposes an energy coordination management strategy to ensure the stability and flexibility of the system under the premise of stable operation of each control unit. By comparing the mixed power output of wind turbine and PV with the load scheduling demand, and taking the rated power of electrolyzer, fuel cell and hydrogen storage tank as the constraints, the system can be smoothly and precisely switched between various operation modes. Finally, time-domain simulation was conducted using Matlab/Simulink software platform, and the simulation re-sults showed that energy can be reasonably allocated, verifying the effectiveness of the proposed energy management strategy.
