Model of Clean Energy Substitution Based on Energy Saving and Emission Reduction Targets

Abstract

Under the situation of increasing air pollution and rapid development of clean energy, actively promoting energy substitution plays an important role in implementing energy strategy deployment and safeguarding energy security in China. This paper puts forward an energy substitution path considering the interaction between different energy sources, and establishes an energy alternative model based on energy saving and emission reduction targets. The proposed model takes the total amount of carbon emissions as the optimization target, and calculates and analyses the energy substitution path and the substitution space by considering the terminal energy consumption characteristics and the restriction of clean energy supply. Finally the paper makes instance calculations on the energy substitution space at the end of 13 th five-year plan and the 14 th five-year plan. The calculation result verifies the feasibility and superiority of the proposed model and solution method.
