Description

Technical Field

[0001] The present invention relates to the technical field of power supply, and in particular to a multi-energy complementary intelligent power supply system. Background Art

[0002] In recent years, with the continuous growth of the energy demand of countries around the world and the increasing emphasis on environmental protection, the popularization and application of renewable energy have become an inevitable trend. At the same time, based on the single operation mode of the existing large power sources and large power grids, emergency accidents such as large-area power supply paralysis are likely to occur. Therefore, the future development focus of China's energy will surely shift to multi-energy complementary distributed energy systems.

[0003] As the most widely used renewable resource, with the development of the solar energy industry, the use of solar energy in household power generation systems and power station power generation systems will be more and more extensive. First of all, at present, most of the fixing methods for solar photovoltaic modules are fixed on the roof or on special solar photovoltaic module brackets. Most of the roofs and special solar photovoltaic module brackets cannot adjust the installation angle. In different regions and different seasons, due to the change of the solar irradiation angle, the angle of the solar photovoltaic modules is fixed, resulting in the power generation efficiency of the solar modules not reaching the best. In windy areas, when the wind force is large, the stress area of the photovoltaic modules is large, and the wind force impact suffered is large. Therefore, the photovoltaic modules are easily damaged and need to be replaced frequently, thus wasting a lot of financial and material resources.

[0004] Secondly, because the photovoltaic power generation panels are installed on the top floor of the building, they are often blown by strong air currents, which will blow a large amount of dust and impurities onto the surface of the photovoltaic power generation panels, thus covering and blocking the surface of the photovoltaic power generation panels and affecting their energy conversion rate. Summary of the Invention
