Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic technology, especially to the field of photovoltaic power generation. Background Art
[0002] With the adjustment of China's energy structure and the continuous increase in the proportion of natural gas in energy utilization, as well as the rise of wind energy, solar energy, and bioenergy power generation, distributed power supply systems have become an important new energy supply method. In recent years, to encourage the development of distributed energy, the state and local governments have introduced a series of support policies, which have promoted the development of distributed energy to a certain extent.
[0003] At present, most traditional photovoltaic power stations are fixed in a certain location. Such fixed photovoltaic power stations have many limitations during use. For example, in some special scenarios, they cannot quickly provide power support. In contrast, mobile photovoltaic power stations have significant energy-saving and emission-reduction effects. Mobile photovoltaic power stations have the advantages of being clean, safe, low-cost, less land occupation, and strong mobility. They can be temporarily set up on idle land in rural areas, pastoral areas, mountainous areas, or near large and medium-sized cities or commercial areas in development. They adopt both grid-connected and off-grid modes to provide reliable power support for scenarios such as emergency disaster preparedness, mobile office, commercial stalls, RV camping, outdoor fishing, and outdoor operations.
[0004] A mobile photovoltaic power station usually consists of a photovoltaic power generation unit, a storage cabinet, an integrated inverter and controller, a grid connection box, an electrical device, and a container body. This design can not only achieve the power generation and storage of photovoltaic electric energy but also realize the free switching between grid-connected and off-grid through the integrated inverter and controller, improving the flexibility and practicability of the system.
[0005] However, there are still some problems in the design of mobile photovoltaic power stations in the prior art. For example, the installation and disassembly of photovoltaic modules are relatively cumbersome, and the system is easily affected by vibration and impact during transportation, thus affecting the power generation efficiency of photovoltaic modules. In addition, the existing photovoltaic power generation units have poor adaptability to local latitude and longitude irradiation in actual applications, resulting in low photovoltaic power generation efficiency.
[0006] Therefore, how to design an urban mobile photovoltaic power generation system with a simple structure, convenient installation, strong adaptability, and high power generation efficiency has become an urgent problem for technicians to solve. Summary of the Utility Model
