Cost Allocation Of Residential Distributed Photovoltaic Systems Under The Resource Constraints In Different Regions Of China

Given the tremendous challenges of global energy conservation,emissions reduction and energy security,the distributed photovoltaic(PV)industry has become a key means of achieving economic restructuring and a low-carbon economy because of its far-reaching significance for improving the supply of clean energy in cities.With the rapid development in recent years,China's distributed PV industry has entered the stage of commercial development,but the the present status of distributed PV development in China is not as favorable as expected.With the fact that the price has dropped a lot within the last five years,irrational cost allocation has gradually become the main obstacle to development of distributed PV in China,it is the most immediate embodiment that our current national and local subsidy policies cannot meet the needs of the development of distributed PV,so how to scientificately and fairly allocate the profits and costs has become the key to solve the problem of distributed PV development limitation in China.The root cause of the unsatisfactory development of distributed PV lies in the externality caused by irrational distribution of interests among different parties,therefore,a mathematical model used to allocate the costs and profits is built and run in this thesis.The main results of the thesis are as follows:(1)Taken 15 Chinese cities' natural,economic,and social conditions into consideration,calculated the LCOE(levelized cost of energy)of on-gird and off-grid residential PV systems.(2)Completed the revenue analysis of gird companies,government and residents based on externality theory.(3)Built the mathematical models based on cooperative game theory under flat-rate and time-of-use pricing,the result analysis is done among residents,government and gird companies by using Shapley,MCRS and Nucleolus methods.(4)The results highlight that: ?1 The main beneficiaries of distributed PV are residents and government,who should bear the majority of the costs,while the grid companies should receive subsidies.?2 Shapley method is more beneficial to residents,while the Nucleolus method is more favorable to grid companies.?3 National subsidies alone cannot satisfy the requirements for distributed PV investment across China and local subsidies play supplementary roles.(5)From the viewpoint of the government,in order to better meet the needs of different regions,?1 tiered pricing and subsidies should be used according to the conditions of local resources.?2 Besides,implementation of the storage subsidy policies,increasing Renewable Power Plus,strengthening project management and developing new business models would play important roles in promoting residential distributed PV industrial development.
