Simulation of hydrogen production microgrid using solar energy storage fuel capacitor electrolytic cell VSG pre synchronization, grid connection, and off grid switching for primary and secondary frequency regulation
1. Energy storage system: Both the battery and supercapacitor are controlled by the voltage outer loop and current inner loop, stabilizing the bus voltage of 750V
2. Fuel cell system: constant power control, single loop, single boost boost, transmitting energy
3. Hydrogen production system: constant power control, single loop, single boost boost, energy transmission
4. Wind turbine system: using MPPT control and variable pitch angle control
5. Photovoltaic system: using the incremental conductivity method, with a power level of around 10kW
6. Inverter control: Adopting VSG pre synchronous grid connection, it can achieve parallel and off grid operation
7. Synchronous generator system: simulates a finite power grid, participates in grid frequency regulation, and can see the frequency transformation of the synchronous generator
