Strategies of stakeholders to promote distributed photovoltaics in China: An evolutionary game study

Abstract

The promotion of distributed photovoltaics (DPV) is significant to prompt the energy structure transformation. There are many participants in the DPV project, and their strategies directly affect the construction and operation quality of the DPV plant and determine whether the DPV promotion can be carried out smoothly. This paper establishes an evolutionary game model among governments, enterprises, and households considering the impact of strategic choices of the three parties on the operational efficiency of DPV power plants. The Chinese DPV incentive policies and the actual situation of the industry are used for numerical simulation to analyze the strategies of stakeholders for DPV promotion. The results show that participants can reach eight stable states under different situations. The effect estimation results show that increasing the initial willingness, financial subsidy, punishment taxes, and operating efficiency coefficient have positive effects on encouraging participants to actively promote DPVs, while the additional costs and investment costs have negative effects. Recommendations are made for the formulation of investment strategies and DPV promotion policies.
