Description

technical field

[0001] The invention relates to the technical field of electric power systems, in particular to a hybrid power generation system used by room air conditioners. Background technique

[0002] Almost all existing room air conditioners are driven solely by conventional electricity provided by the public grid. With the exhaustion of energy sources, energy conservation and emission reduction are becoming more and more urgent. Currently, new and clean energy sources are used to replace conventional energy sources. It has been valued by all walks of life, and solar energy, as a clean energy source, is being used more and more widely, which meets the needs of the country's energy conservation and emission reduction policies. However, at present, photovoltaic solar power generation is relatively expensive, the power generation efficiency is not very high, and the use of room air conditioners is relatively large, so the use of photovoltaic solar energy in room air condi...
