Source-load Coordinated Carbon Reduction Optimal Scheduling of Integrated Energy System Considering Ultra-carbon Demand Response
With the rapid development of new energy in the northwest of China,making full use of the unique advantages of local light and heat resources,combined with the low-carbon transformation of thermal power and the coordinated operation of new energy,is conducive to promoting the green and low-carbon transformation of the local energy system.To maximize the carbon reduction capacity of the system,this paper proposes an ultra-carbon demand response model based on source-load collaborative carbon reduction.The dynamic carbon emission factor is used as the penalty factor of the time-of-use price so that the source-side carbon signal is transmitted to the load side,driving the user side to carry out low-carbon state transfer.Firstly,in the day-ahead scheduling stage,a two-stage scheduling mechanism of pre-scheduling-re-scheduling is constructed.The re-scheduling responds to the ultra-carbon demand according to the system status information of the pre-scheduling to reduce the system carbon emission in depth.Secondly,the concentrating solar power plant is introduced into the integrated energy system to operate in coordination with the wind farm and the carbon capture power plant to construct a high proportion of new energy scenarios to verify the carbon reduction benefits of the ultra-carbon demand response in this scenario.Finally,a pre-scheduling and rescheduling two-stage low-carbon scheduling model based on super-carbon demand response is constructed.The simulation analysis of the example shows that the new idea of source-load synergistic carbon reduction can effectively improve the carbon reduction capacity of the system,deeply explore the carbon reduction space of the system,and improve the economic benefits of the system.
