The input end of the energy management system is connected with the photovoltaic module, the power grid, the user load and the battery management system arranged on the energy storage battery. The output end of the energy management system is connected with the light storage integrated converter, and according to the light storage system, the problems that an existing photovoltaic powergeneration system is unstable, intermittent, low in photoelectric efficiency and difficult to maintain can be solved.

Description

technical field [0001] The invention relates to the technical field of optical storage systems, in particular to a modular household optical storage system capable of automatic energy scheduling and a control method. Background technique [0002] Energy is the material basis for human beings to survive. The limited and extensive exploitation and utilization of fossil energy have led to increasing energy shortages and environmental pollution. Solar energy is currently one of the cleanest and most promising renewable energy sources. received widespread attention. [0003] However, due to the influence of various factors such as the environment, the power generation capacity of the photovoltaic power generation system will be relatively high in a certain period, but the power generation capacity in a certain period will be relatively low, resulting in unstable power provided by the photovoltaic power generation system, resulting in The user's power supply is intermittent, and ...
