Abstract
With the rapid development of the PV industry,the installed capacity of PV power generation continues to increase,but the situation of abandoned PV power and power limitation in northwest China is more serious.And power limitation will have an impact on the design scheme of PV power stations.This paper takes the design of a large centralized PV power station in Qinghai Province as an example,and analyzes the impact of power limitation on the design scheme of PV power stations by sorting and analyzing relevant data of similar PV power stations built nearby.The analysis results indicate that:1)there is a certain relationship between the power limitation,the power limitation rate,and the output power of PV power generation.2)When the benchmark power limitation rate is determined,the smaller the DC/AC ratio,the smaller the annual power limitation rate.3)The annual power limitation rate decreases with the increase of the operating years of the PV power station throughout its 25 year lifecycle.The larger the benchmark power limitation rate,the smaller the optimal DC/AC ratio obtained based on the minimum LCOE,indicating that power limitation has an impact on the selection of DC/AC ratio.Due to the use of a power limitation analysis method that is closer to the actual power limitation situation of PV power stations,the resulting design method for PV power stations is also more reasonable.The research results are expected to provide reference for the design of PV power stations under power limitation.关键词
