Problems solved by technology

[0004] However, in the prior art, the power supply technology based on BIPV still has deficiencies.
When the lighting conditions are good, the electric energy generated by photovoltaic modules greatly exceeds the actual energy required by the lighting devices in the building. Therefore, the excess electric energy generated by photovoltaic modules cannot be well utilized, resulting in low energy utilization.
In addition, when the lighting conditions are not good, the power generated by the photovoltaic modules is insufficient to supply power to all the electrical equipment in the building. Therefore, the power supply performance of the BIPV-based power supply technology in the prior art is not stable.

Abstract

The invention discloses a lighting power supply system based on photovoltaic building integration. The system is connected with a power grid. The lighting power supply system based on photovoltaic building integration comprises a power generation unit, which is connected with the power grid; a lighting unit, which is connected with the power generation unit and the power grid; and an energy storage unit, which is connected with the power generation unit and the lighting unit. The power generation unit is connected with the energy storage unit, so that electric energy generated by the power generation unit can be stored in the energy storage unit, and the electric energy stored in the energy storage unit can supply power to the lighting unit when the illumination intensity is poor and the power generated by the power generation unit is insufficient, and the phenomenon of unstable power supply caused by insufficient power generation is prevented. The system is connected with the power grid, and when the illumination intensity is good, residual electric energy is fed back to the power grid after the electric energy generated by the power generation unit is stored in the energy storageunit, so that high utilization rate of the energy is achieved.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a lighting power supply system based on photovoltaic building integration. Background technique [0002] With the development of science and technology, more and more new energy sources are gradually being developed and used, such as photovoltaic, wind energy, tidal energy, geothermal energy, etc. are gradually being developed and utilized. In order to promote the use of renewable energy and reduce the impact of traditional power stations on the environment, the use of new energy for power generation is gradually being adopted. [0003] Most of the traditional use of new energy to generate electricity is to build new energy power stations, which not only take up a lot of space, but also have an impact on the environment. Since most of the power stations are not located in residential areas and industrial areas, the consumption of transmission lines is large, and cons...
