Research on Static Evaluation of Economic Value of "Distributed PV plus " Model

Due to the shortage of fossil energy, environmental pollution, climate change and a series of problems, China is developing photovoltaic (PV) energy and other clean sources of energy. The flexible application of photovoltaic energy makes is an ideal choice. First, this paper clearly describes the significance of the economic value of a PV + model, analyzes its composition of, and then builds the PV + economic value evaluation model. Finally, a PV + model from the agriculture and aquaculture industry is taken as an example to evaluate its economic value. Through data calculations, the feasibility of the PV + economic value evaluation model proposed in this paper is verified. The results show that the model can not only promote the development of photovoltaic energy, but also bring a spillover value to the decentralized economy. The contributions of this paper are as follows: (1) The existence of the spillover value of a PV + model is proposed for the first time. (2) The value of the distributed PV + model is revealed from its essential attributes and characteristics, and a method for the quantitative calculation of the spillover value is proposed. (3) Three cases of the spillover value for the economic value of the PV + model are proposed, and the relationship between the spillover value and local adoption of PV + model to absorb distributed PV is discussed.
