Thin-film solar building integrated power generation household off-grid microgrid adjusting system

Abstract

The invention discloses a thin-film solar building integrated power generation household off-grid microgrid adjusting system. The system comprises a photoelectric conversion unit, a monitoring unit, acontrol unit, a distribution box unit, a power distribution module, an inversion unit, an anti-countercurrent unit, a registration and login unit and a database. The use information of the householdelectrical appliances is analyzed through a power distribution unit to carry out reasonable power distribution on the household power consumption, and the use frequency and use frequency of the household electrical appliances are obtained; household electrical appliances are divided into four grades, the household electrical appliances are sorted according to the grades from small to large, powergenerated by the thin-film solar building integrated power generation system is consumed nearby and is preferentially used by the electrical appliances defined in a household network through a power distribution module, the insufficient part is seamlessly switched and compensated by a power grid port, resource comsumption is reduced, and household electric appliances can be graded and classified,so that the electric energy use efficiency and the recovery efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic adjustment, in particular to an off-grid micro-grid adjustment system for household off-grid micro-grid for thin-film solar building integrated power generation. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The key components of this technology are solar cells, which can be packaged and protected to form a large-area photovoltaic cell module after being connected in series. At present, under the stimulation of fossil energy shortage, CO2 emission reduction pressure and national fiscal policy, photovoltaic power generation has become the fastest growing renewable energy power generation technology in the world. In recent years, the Chinese government has also issued a series of policies to encourage and promote the development of the ...

Problems solved by technology

[0003] However, in the prior art, it is impossible to monitor the thin-film solar power generation components during the working process of the thin-film solar power generation components for solar power supply, and it is not enough to convert the electricity generated by the thin-film solar power generation components from direct current to alternating current, and it is not possible to convert redundant Electric energy is used for household power supply, which wastes resources and reduces the power recovery rate
