Impact of Carbon Trading Price Parameters on the Optimization of Integrated Energy System

Controlling and reducing carbon emissions has become an important challenge. The stepped carbon trading mechanism, as a flexible market-based instrument, provides a new strategy for carbon emission management in the Integrated Energy System (IES) and promotes the economic and low-carbon development of the system. This study constructs an IES model based on a stepped carbon trading mechanism and incorporates relevant operational constraints. Minimizing the total cost of IES as the objective function, and the commercial solver CPLEX was used to solve it to achieve the optimal operating goal. As a key factor in carbon trading, changes in carbon price parameters can affect carbon trading cost and total cost, leading to changes in IES scheduling optimization strategies. To investigate the impact of changes in carbon price parameters on the optimization of IES, simulations were conducted to verify the system by altering the base price and interval length. The results show that the system can flexibly adjust the equipment output according to the change of carbon price parameters to change the carbon emissions, so as to achieve the optimal operation of the system.
