Abstract
An electrical energy control method and an electrical energy control apparatus for a photovoltaic system are provided. With the electrical energy control apparatus, a photovoltaic module meeting a preset electrical energy reverse flow condition is controlled to receive electrical energy stored on a direct current capacitor of the electrical energy control apparatus. That is, the photovoltaic modules are separately controlled to be heated by corresponding electrical energy control apparatuses, so as to avoid the issue in conventional technologies that, due to unified heating, excessive reverse power is received by some modules and causes performance degradation or damage of the modules, thereby ensuring that each of the photovoltaic modules is safely and reliably controlled to be heated for snow melting and deicing.
