In this paper, the ratio of non-fossil energy consumption is determined, and the case of energy transformation is analysed according to "double-carbon" goal restriction, and the system combination is also discussed. On the basis of the dynamic coupling of power supply structure and energy structure, this paper derives the process of decarbonization of power system by using the ratio of non-fossil energy. Based on this, the paper further divides the power supply structure into three phases, and puts forward the strategy of "Three Steps" to construct a new electric power system.
Aiming at the problem that there are many factors affecting the comprehensive energy service level and it is difficult to quantitatively analyze them, this paper proposes a comprehensive evaluation method of the comprehensive energy service level based on ANP. Firstly, a comprehensive evaluation index system of comprehensive energy service level is constructed from five aspects: management level, economic benefit, operation effect, social impact and sustainable development level. Secondly, in order to achieve comprehensive evaluation, ANP method is used to solve the corresponding weight of the proposed comprehensive energy service level evaluation index. Through case analysis, important indicators are obtained. so as to provide reference for the operation and development of future integrated energy service providers
