Distributed photovoltaic power plant usually refers to the use of decentralized resources, the installation of small-scale, arranged in the vicinity of the user power generation system, it is generally connected to the grid below 35 kV or lower voltage level. Distributed photovoltaic power plant refers to the use of photovoltaic modules, the direct conversion of solar energy into electricity distributed photovoltaic power plant system.
The most widely used distributed PV power plant systems are PV power generation projects built on the rooftops of urban buildings, which must be connected to the public grid and supply power to nearby customers together with the public grid. Without the support of the public grid, the distributed system cannot guarantee the reliability and quality of electricity for customers.
Characteristics of distributed photovoltaic power plants
1. the output power is relatively small
Traditional centralized power plants are often hundreds of thousands of kilowatts or even millions of kilowatts, the application of scale has improved its economy. The modular design of photovoltaic power generation determines that its scale can be large or small, and the capacity of the photovoltaic system can be adjusted according to the requirements of the site. Generally speaking, the capacity of a distributed PV power plant project is within a few thousand kilowatts. Unlike centralized power plants, the size of the PV power plant has little impact on the efficiency of power generation, so the impact on its economy is also very small, the return on investment of small PV systems is not lower than that of large ones.
2. pollution is small, and environmental benefits are outstanding.
Distributed photovoltaic power plant project in the power generation process, there is no noise, but also will not produce pollution of air and water. However, need to pay attention to the distributed photovoltaic and the surrounding urban environment of the coordinated development, in the use of clean energy, considering the public’s concern for the beauty of the urban environment.
3. It can alleviate the local electricity tension to a certain extent
Distributed photovoltaic power plants have the highest power output during the day, just when people have the greatest demand for electricity during this time. However, the energy density of distributed photovoltaic power plants is relatively low, the power of each square meter of distributed photovoltaic power plant system is only about 100 watts, coupled with the limitations of the roof area of buildings suitable for the installation of photovoltaic modules, so distributed photovoltaic power plants can not fundamentally solve the problem of electricity tension.
