Research on the decomposition model for China’s National Renewable Energy total target

It is crucial that China’s renewable energy national target in 2020 is effectively decomposed into respective period targets at the provincial level. In order to resolve problems arising from combining the national and local renewable energy development plan, a total target and period target decomposition model of renewable energy is proposed which considers the resource distribution and energy consumption of different provinces as well as the development characteristics of various renewable energy industries. In the model, the total proposed target is comprised of three shares: basic share, fixed share and floating share target. The target distributed for each province is then determined by the preference relation. That is, when total renewable energy target is distributed, the central government is more concerned about resources potential or energy consumption. Additionally, the growth models for various renewable energy industries are presented, and the period targets of renewable energy in various provinces are proposed in line with regional economic development targets. In order to verify whether the energy target can be achieved, only wind power, solar power, and hydropower are considered in this study. To convenient to assess the performance of local government, the two year period is chosen as an evaluation cycle in the paper. The renewable energy targets per two-year period for each province are calculated based on the overall national renewable energy target, energy requirements and resources distribution. Setting provincial period targets will help policy makers to better implement and supervise the overall renewable energy plan.

It is very importance that the national target of renewable energy in 2020 can be effectively decomposed into the stages target of various province. In order to resolve the relation the plan between the national and local renewable energy development planning, a total target and phase target decomposition model of renewable energy was proposed considering the resource distribution, energy consumption of different provinces and the development characteristics of various renewable energy industry. In the model, the total target includes three shares: basic share, fixed share and floating share target. The preference relation was determined between the resource potential and energy consumption in the process of target distribution. The growth model for various renewable energy industries was presented. Combination with regional economical development targets, the phase targets of renewable energy in various provinces were proposed. In order to verify the correctness of the model, as the represented energy, wind power, solar power and hydropower were considered in the study. The phase targets of renewable energy in various provinces were proposed combinative the overall planning of national renewable energy, energy requirements and resources distribution. It is of certain significance to implement and supervise the overall plan of renewable energy.
