Abstract

The invention discloses a distributive independent photovoltaic power generation system and method. The distributive independent power generation system comprises a plurality of independent photovoltaic power generation systems which are connected in parallel, wherein each independent photovoltaic power generation system is connected to a corresponding load, and the independent photovoltaic systems are controlled by an electric energy interaction management system; the electric energy interaction management system comprises a load on-off information acquisition unit and a storage battery electricity quantity information acquisition unit, wherein the load on-off information acquisition unit is used for acquiring on-off information of the loads, and the storage battery electricity quantity information acquisition unit is used for acquiring electricity quantity information of a storage battery in each independent photovoltaic power generation system; and the electric energy interaction management system further comprises a processing control module which is used for carrying out data processing on the on-off information and the electricity quantity information to output a control signal and carrying out on-off control on the inverter in each independent photovoltaic power generation system, so that the electricity quantity of the storage battery in each independent photovoltaic power generation system keeps at a balanced state.

Description

Technical field [0001] The invention relates to the field of solar power generation, in particular to a distributed independent photovoltaic power generation system and a power generation method. Background technique [0002] Photovoltaic power generation system is a power generation system that directly converts solar energy into electrical energy. Because of its high reliability, long service life, no environmental pollution, and independent power generation, photovoltaic power generation systems are favored by many users and have broad development prospects. [0003] At present, the independent photovoltaic system can be applied to each household, install photovoltaic panels in each household, store solar power and provide it to low-power loads, such as energy-saving lamps, televisions, fans, computers, small refrigerators and other low-power Load usage. [0004] However, current photovoltaic power generation systems are completely independent units, which cannot be interconnecte...
