考虑不同补贴方式的分布式光伏运维模式决策

Decision on operation and maintenance modes for distributed PV power generationconsidering different subsidies

针对我国分布式光伏的不同补贴政策,首先建立分布式光伏的全寿命周期成本效益模型,然后对比不同典型运维模式的特点,通过净现值、内部收益率和动态投资回收期3个指标对不同补贴方式下采用不同运维模式时的分布式光伏经济效益进行量化。最后通过某案例计算,对比分析了运维公司盈利率和自用电量比例对分布式光伏用户效益的影响,为光伏用户选择合适的补贴方式和运维模式提供参考。

Based on different subsidies for distributed photovoltaic(PV)power generation in China,the cycle-life cost and benefit models of distributed PV are established in this paper,and characteristics of typical operation and maintenance(O&M)modes of PV are compared and discussed.Three economic indicators,including Net Present Value,Internal Rate of Return and Dynamic Payback Period,are used to evaluate the economic benefits of PV users under different O&M modes and different subsidies.Finally,a case study is carried out,and two main influent factors for economic benefits of PV users are discussed,including profit margins of O&M company and the proportion of electric power consumption for personal use.This study can provide reference for PV owners to operate under different subsidy and O&M modes.
