The paper proposes an optimal scheduling model based on CCHP and carbon capture device to achieve the low-carbon operation of the integrated energy system by considering demand response and ladder-type carbon trading mechanism. The model takes into account the demand response of cooling, heating, and electricity load based on time-of-use electricity price and incentive mechanism, and establishes a carbon trading model considering the actual carbon emissions and ladder-type carbon trading mechanism. By solving the mixed integer linear problem using CPLEX, the results show that the system total cost can be reduced by 5.9% with ladder-type carbon trading, and further reduced by 3.1% after considering user-side demand response. The simulation results demonstrate the flexibility of load transfer, reduced gas purchase, and decreased system carbon emissions with the introduction of demand response and ladder-type carbon trading, providing significant application value.
The low-carbon economy operation of the integrated energy system can be realized by introducing the demand response and carbon trading mechanism into the optimal scheduling of the integrated energy system. In this paper, an optimal scheduling model based on CCHP and carbon capture device is proposed, which takes into account the demand response of cooling, heating and electricity load and ladder-type carbon trading mechanism. Firstly, a multi-energy and multi-type demand response model based on time-of-use electricity price and incentive mechanism is established, and user satisfaction is used to evaluate it. Then, a carbon trading model of integrated energy system is established considering the actual carbon emissions of the system and the ladder-type carbon trading mechanism. Finally, taking the minimum sum of energy purchase cost, maintenance cost, carbon emission cost and compensation cost as the objective function, combined with the operation constraints of multi -energy flow of integrated energy system, an optimal scheduling model which takes into account both low-carbon and economy is constructed, and the problem is transformed into a mixed integer linear problem and solved by CPLEX. By setting up four scenarios for example analysis, the results show that the system total cost of the ladder -type carbon trading is decreased by 5.9% compared with the traditional carbon trading, and on the basis, the system total operating cost is decreased by 3.1% after considering the user-side DR. The simulation results further show that the introduction of DR and ladder-type carbon trading mechanism can flexibly transfer load, reduce gas purchase and reduce system carbon emissions, which has significant application value.
