Embodiment Construction
[0070] The specific process is attached figure 1 As shown, the present invention proposes a photovoltaic hydrogen production system control method based on the conductance incremental method. The method is based on the step-down converter control, and can quickly determine the maximum power point for the power fluctuation problem caused by photovoltaics due to changes in light temperature. At the same time, it can well adapt to the electrolysis system that requires high current and low voltage working environment and can well adapt to power fluctuations, and can improve the hydrogen production efficiency while ensuring the stable operation of the system.
[0071] A control method for a photovoltaic hydrogen production system based on the conductance incremental method includes the following steps:
[0072] Step 1. Collect voltage and current information output by photovoltaic cells under different working environments;
[0073] Step 2. Analyze the photovoltaic step-down conve...
