[Abstract]:It is necessary to compare the economy between centralized photovoltaic generation and distributed photovoltaic generation. Based on the regional differences in the construction and development of photovoltaic power plants, and on the basis of the traditional calculation method of cost and electricity price of photovoltaic power stations, considering the actual cost of users, the paper puts forward the generation and transmission of remote centralized photovoltaic power stations and nearby distributed photovoltaic power stations. Distribution topology model. The transmission efficiency of photovoltaic power station in the process of power generation, transmission and distribution is analyzed. The loss of photovoltaic system and the cost of transmission and distribution are incorporated into the cost of photovoltaic power, and a new method is established to evaluate the generation and transmission of photovoltaic system. The calculation model of efficiency and cost in the whole process of distribution is given, and the concrete comparison process is given with practical examples. The results show that the number of hours of illumination, the distance of transmission and the investment of unit capacity of photovoltaic power station are the main factors that affect the cost difference between remote centralized photovoltaic power station and local distributed photovoltaic power station.
