Comprehensive energy system cost analysis method based on analysis

The invention discloses an integrated energy system cost analysis method based on # imgabs0 # analysis, and belongs to the technical field of energy systems. The electricity-to-gas conversion device is coordinated and matched with the carbon capture power plant, cyclic utilization of carbon is formed, and economical efficiency is improved while carbon emission is reduced; a # imgabs1 # economic analysis method is introduced, the quantity and quality of energy are considered, a # imgabs2 # value calculation method of different energy flows is refined, and a # imgabs3 # flow calculation sub-model is established; in order to further realize low-carbon emission reduction, carbon emission permit transaction cost, carbon capture energy consumption cost and carbon sequestration cost are brought into non-energy cost, and a # imgabs4 # economic cost sharing sub-model is established. According to the method, the influence of the carbon cost and the energy grade difference on the cost of the system cooling, heating and
