Abstract: With the increasingly prominent energy problems, especially the gradual improvement of environmental awareness, photovoltaic power generation has gradually become one of the leading technologies in the field of new energy power. As a new type of photovoltaic power generation, distributed photovoltaic power station has its own characteristics and advantages. With the increasing demand for renewable energy in society, distributed photovoltaic power station will certainly gain greater development opportunities and market potential in the future development trend. From the perspective of electrical design of distributed photovoltaic power station, this paper analyzes the electrical design technology in the process of power station grid connection, summarizes the application of electrical design technology in the construction of distributed photovoltaic power station, and provides practical guidance for comprehensively promoting the construction of distributed photovoltaic power station.
