This application provides a power supply method, device, system, medium, and product for a photovoltaic thermal energy storage system, relating to the field of photovoltaic power generation. The method obtains the state of charge (SOC) of the energy storage system and the output capacity of the shared bus capacitor inertia. When the energy storage capacity is sufficient and the bus inertia support capacity is normal, multiple power sources are used to power the system. However, under extreme conditions where the energy storage capacity is insufficient and the shared bus capacitor inertia support capacity decreases, the system no longer relies solely on electrical side resources. Instead, it combines the temperature of the heat transfer medium, the thermal storage state, and the heat demand on the thermal side to adjust the operation of the thermal side and output compensating power. Multiple power sources and thermal side compensating power are jointly injected into the shared bus capacitor, compensating for the power supply gap caused by insufficient energy storage resources and decreased capacitor buffer capacity. This improves the power supply reliability and power quality of the photovoltaic thermal energy storage system under multi-source fluctuations, sudden load changes, and extreme conditions, avoiding problems of power quality degradation and power outages.

Mode-smooth switching is achieved through continuous cyclic adjustment and preset stability judgment conditions.
