Abstract
Due to factors such as terrain,plot size,distance between plots,and construction conditions,the PV power to inverter power ratio of each PV array in PV power station usually differs from the optimal design PV power to inverter power ratio of the PV power station.This paper starts from the perspective of analyzing the PV power to inverter power ratio of various PV arrays in PV power stations,and systematically analyzes the discreteness of the PV power to inverter power ratio of PV arrays.Based on genetic algorithm,the distribution of the PV power to inverter power ratio of PV arrays in PV power stations is optimized firstly,and then the influence of the discreteness of PV array PV power to inverter power ratio on the overall power generation capacity of PV power stations is studied,and relevant syggestions are given.The research results show that:1)For flat PV power stations,an increase in the discreteness of PV power to inverter power ratio will lead to a decrease in the power generation capacity of PV power stations,and the rate of increase in power generation capacity loss will gradually accelerating.If the plots in the PV field are relatively scattered,the combination of large and small installed capacity PV arrays can be used to minimize the loss of PV power generation capacity of PV power stations caused by the discreteness of the PV power to inverter power ratio.2)For mountainous PV power stations with complex terrain,for plots with good orientation and slopes,the actual PV power to inverter power ratio can be set to a value equal to or slightly lower than the design optimal PV power to inverter power ratio.For plots with poor orientation and slope,the actual PV power to inverter power ratio can be higher than the design optimal PV power to inverter power ratio.The distribution of PV power to inverter power ratio within a certain range of discreteness can better adapt to complex terrain,and can increase the economic benefits of PV power stations.关键词
