With the rapid development of society, the demand for energy is increasing day by day. However, traditional power generation and energy methods such as coal-fired and hydroelectric power generation will bring a series of environmental problems, seriously affecting people's quality of life. Increasing the development and utilization of renewable energy and reducing the use of fossil fuels are the focus of energy development today and in the future. Solar power generation technology is one of the key directions of renewable energy development. After many years of development, solar power generation has formed two basic power generation technologies, solar photovoltaic power generation and solar thermal power generation. The key to the application of solar power generation technology is to solve the independent operation of solar equipment and the safe grid-connected operation of equipment.
The solar photovoltaic power station can be divided into two types: independent and grid-connected according to whether it is connected to the public power grid. The type of solar PV energy system used needs to be selected based on the reference power supply demand to choose the most reasonable solar PV energy system.
The design of the solar PV energy system mainly focuses on the capacity of the solar PV energy system and the selection of the power electronic equipment in the solar PV energy system, as well as the design and calculation of ancillary facilities. The design of capacity mainly targets the capacity of the battery components and batteries in the solar PV energy system, and the focus is to ensure that the stored electricity of the battery can meet the work requirements. The selection and configuration of system components in the solar PV energy system should ensure that the selected equipment matches the capacity design of the solar PV energy system, thus ensuring the normal operation of the solar PV energy system.
When designing the capacity of independent solar PV energy system, first list out the load and local dimensions of the independent solar PV energy system to determine the size and power consumption of the load of the independent solar PV energy system. Based on this, select the capacity of the battery in the independent solar PV energy system.
Then, by calculating the array current of the independent solar PV energy system, determine the optimal current of the independent solar PV energy system, then determine the array voltage of the battery in the independent solar PV energy system, and finally determine the power of the battery in the independent solar PV energy system. When designing the power of the battery array in an independent solar PV energy system, it is possible to complete the design of the solar cell array of the independent solar PV energy system according to the principles of series-boosting and parallel-rectifying.
