In the off-grid hydrogen production scenario, the power comes from wind power generation/PV power generation/energy storage system, etc. In this scenario, due to a lack of large grid support and big volatility in the microgrid, the hydrogen production power supply is required to operate at a wider range of voltage and frequency fluctuations. Hopewind EMS coordinated control of renewable energy, energy storage and hydrogen production, enables efficient system response, coordinated output of active and reactive power, fast regulation of the energy storage system, and suppression of volatility in new energy power generation, ensures safe and efficient hydrogen production. Off-grid systems can be classified into AC coupling system, and DC coupling system.
