摘要
光伏系统的发电能力及系统经济性受地区辐照度、系统损耗、环境温度、系统容配比等参数影响,其中直流侧组件容量与逆变器交流输出容量的配比参数至关重要。光伏"领跑者"及竞价上网背景下,为降低系统的度电成本,本文分析典型"领跑者"基地不同容配比条件下光伏系统的实际输出功率及度电成本(LCOE),为提升系统经济性及合理设计光伏组件与逆变器的容配比提供理论依据和实际参考。
The power generation capacity and economy of the PV system are affected by the parameters such as the region＇s irradianee, system loss, ambient temperature, system capacity ratio, etc., among which the ratio of the DC side module capacity and the AC output capacity of the inverter is very important. Under the background of ＂Top Runner Program＂ of the photovoltaic industry and bidding for interconnection to grids, in order to reduce the levelized cost of energy （LCOE） of the system, this paper analyzes the actual output power and LCOE of the PV system in a typical ＂Top Runner Program＂ base under different capacity ratios, to provide a theoretical basis and practical reference for improving the system economy and optimizing the capacity ratio of PV module and inverter.
