Cost Allocation of Residential Distributed PV Project Based on Cooperative Game Theory

The thesis analyzed the cost allocation of distributed photovoltaic power generation system in China by discussing 15 cities' natural conditions and their subsidy policies as to photovoltaic power generation, focusing on the promising prospect of the system in the country’s living buildings, using tools including SAM, SOBRA and MATLAB and taking externality theory and cooperative game theory as the theoretical foundation. The analysis results revealed that state subsidies couldn't benefit the residents in a fair way and local subsidies, to a great extent, decided the development level of distributed photovoltaic system in the region, the sum of which basically was between what was calculated by Shapley value method and by the nucleolus method, that the insufficient amount of local subsidies, low residential electricity price and difficulties obtaining subsidies for power grid companies have led to, as far as the players are concerned, less motivation to invest distributed photovoltaic system, which has developed slower than the expectation.
