摘要: 户用分布式光伏逐渐成为我国光伏发展的重要力量,面临上网电价补贴退坡的大趋势,采用系统动力学方法,构建了户用光伏发展的因果环路模型,分析了相关因素及其反馈机制,进一步构建了系统流图模型,对基于补贴退坡的多种组合情景下户用光伏的投资回报、装机容量及新增装机FIT补贴成本的发展演化进行了动态仿真。结果显示,目前户用光伏具备补贴退坡条件,未来3年内可退至0.05~0.1元/(kW·h)并逐步取消补贴;退坡过程需综合考虑FIT退坡幅度、纳入补贴的装机规模、装机目标及补贴成本,以促进我国户用光伏的可持续发展。

Abstract: Residential Distributed Photovoltaic Generation (R-DPVG) has become the important developing force of PV generation in China. As the declining of Feed-in-Tariff (FIT), system dynamics method is used to construct a causal loop model for R-DPVG’s development, and relevant factors and their feedback mechanism are qualitatively analyzed. Then a stock-flow model is build, and the ROI, installed capacity, and policy subsidy costs of R-DPVG are simulated under some combined scenarios based on declining FIT. The simulation proves R-DPVG’s FIT will be reduced to 0.05 ~ 0.1 yuan/(kW?h) in the next three years till cancelled. FIT cutting amplitude, capacity and targets of installation and cost of the FIT subsidy should be comprehensively considered in policy-making to promote R-DPVG’s sustainable development in China.

Key words: R-DPVG, accumulated installation capacity, ROI, costs of FIT policy, system dynamics
