Description
At present, integrated energy system (IES) suffers high operating cost due to poor energy saving and low emission reduction and insufficient consumption of renewable energy though wind and solar energy production are abundant. Thus, a low-carbon economic operation model is proposed in this paper. This model combines the characteristics of flexible load on the demand side and operates jointly with combined heat and power (CHP), carbon capture system (CCS), and power to gas (P2G). It considers the combination of source-side scheduling and demand-side scheduling. Finally, the problem is solved using MATLAB/YALMIP to call GUROBI and the interior point method (IPOPT) based on Hessian matrix iteration. The results show that the reasonable scheduling of the flexible load on the demand side realizes the peak load shifting and reduces the peak load regulation pressure of the system. The operation mode of source-side CHP coupled with CCS and P2G improves the utilization of renewable energy and curtails the carbon emission of the system. The proposed model transaction cost and daily operating cost are less than the base case by 61.34% and 50.49%, respectively.
