At present, for household photovoltaic systems, the methods of demand-side management [14,15,16], modified MPPT algorithm [17,18,19,20,21,22,23,24,25], and energy storage system access [26,27,28,29] are commonly used to restrict the output power of the inverter to meet the grid requirements and improve the friendliness of PV power generation.
Integrating energy storage, such as lithium-ion battery packs, with PV inverters enables stable storage and release of excess electrical energy for future use. Smart grids can maximize the use of solar panels by automatically detecting and regulating grid voltage and frequency, providing a more stable and reliable energy supply.
