Feasibility of solar photovoltaic power generation system and grid-connected power generation

The solar photovoltaic power generation system is currently mainly used in remote areas without electricity or lack of electricity, as an independent power source to supply power to household appliances and lighting equipment. With the shortage of electricity and the increasingly serious problems of environmental pollution, the solar power generation system connected to the public grid has shown increasing competitiveness. The grid-connected operation of photovoltaic power generation will save the energy storage link in the independent photovoltaic system-battery, thus greatly reducing the maintenance of the power station. Due to the short life of the battery, after the battery is omitted, the life of the power generation system can be equal to that of the solar cell. quite. The grid-connected power generation can play a role in reducing the pressure on the AC grid during the peak period of industrial power consumption during the day. Compared with stand-alone PV systems that must meet load requirements at any time, grid-connected PV systems are simpler to configure. Often it can be simplified to selecting PV components and suitable inverters, and finding the correct ratio between the capacities of PV arrays and inverters. In 1993, several power companies in the United States announced that the world's largest a-Si photovoltaic power station had been officially put into operation through expert acceptance. The power station is located in; Davis, California. It covers an area of u200bu200b20,000 square meters and costs 1.6 million US dollars. According to the contract, it will provide 400KW of AC power to meet the needs of 150 American households. The power station was designed and installed by the technicians of the former Croner Company, and was later taken over by APS Company. One of the largest electricity utilities in the United States, Pacific Gas u0026 Electric, and several other major power companies have integrated the plant into the grid.
