Photovoltaic thermoelectric MPPT control method, system and equipment and storage medium

The invention discloses a photovoltaic thermoelectric MPPT control method. The method comprises the following steps: obtaining step length data of a photovoltaic thermoelectric coupling system through a step length counter; judging the total power of the current photovoltaic power generation and thermoelectric power generation and the total power of the photovoltaic power generation and thermoelectric power generation in the previous disturbance period, and processing a step counter according to the ratio of the current total power to the total power of the previous disturbance period; acquiring a temperature difference and a voltage difference between the current period and the previous disturbance period of the system, and determining a step length given value of the next disturbance period according to the product of the temperature difference and the voltage difference, the temperature difference and the voltage difference; determining a step length proportion according to a calculation result of the step
