Abstract:

How to transmit the redundant photovoltaic power to the power grid is currently an important obstruction to the development of China's photovoltaic industry, and the coordination and cooperation among generation, transmission, distribution, and sales of electricity is an effective way to solve this problem. The cooperation and operational decision- making on pricing, the energy storage capacity, carbon emission reduction in a photovoltaic supply chain, which is composed of two heterogeneous power plants (i.e. a photovoltaic power plant and a thermal power plant), single grid company and single power sale company under the renewable energy portfolio standard are studied. First, the game models are respectively constructed for three scenarios: non-cooperative mode, the model of cooperation between the grid company and two heterogeneous power plants, and the model of cooperation between the grid company and the power sale company. Second, the optimal energy storage capacity level, carbon emission reduction level, electricity price and total electricity demand are acquired and analyzed in each scenario. The results show that compared with non-cooperative model, the sale price and the photovoltaic power curtailment radio reduce, the energy storage capacity level, the carbon emission reduction level and the total electricity demand increase, and the overall profit of the supply chain is improved, and its members achieve three-way Pareto improvement in two cooperative models. With the increase of the unit excess consumption voucher price, the photovoltaic on-grid electricity price or the photovoltaic on-grid electricity quantity increases, while the thermal on-grid electricity price or the thermal on-grid electricity quantity decreases. As the unit excess consumption voucher price rises, the proportion of photovoltaic on-grid electricity quantity to total on-grid electricity quantity increases. However, increase of the weight of renewable energy consumption responsibility is not always able to increase the proportion.

Key words: photovoltaic supply chain, vertical cooperation, photovoltaic power curtailment radio, renewable energy consumption
