Economics Reasearch for Photovoltaic Power Generation Project Based on Different Business Model

This paper presents an in-depth economic analysis on Photovoltaic power generation (PV) project. The research is based on nine business and technical proposals which with different investment operational pattern and different distributed generation (DG) integration technology of PV project. An all-life-cycle benefit/cost (B/C) assessment methods was used to assess the feasibility of the project. Through the accurately simulate of an annual PV output and load curves from typical time, received electric power and energy balance calculations and revenue forecast results. And then different operators’ electricity price benefits based on china’s complex tariff mechanism was estimated in this paper, while the initial PV panel investment, operation and maintenance, distribution network investment and losses of PV projects were calculated. Finally, through the PI value come to the best business model. Calculation results show that if power grid enterprise as the PV power producer, and use of virtual power plant technology for DG integration means more investment value than other business mode.
