Coordinated optimization dispatch of multi-integrated energy systems considering carbon-green certificate interaction mechanism

In order to improve the low-carbon economy and flexibility of electricity supply and demand of the electric-thermal integrated energy system, this paper proposes a collaborative optimization scheduling method for multiple integrated energy systems considering the carbon-green interaction mechanism. First, the carbon-green equivalent interaction mechanism is described to construct a carbon-green certificate joint transaction cost model. Secondly, the integrated demand response is introduced, and on this basis, a multi-integrated energy system cooperative operation model is constructed with the goal of minimizing the total system cost. Finally, a case simulation is carried out, and the superiority of the mechanism proposed in this paper is verified by setting different scenarios. The case results show that the strategy can effectively reduce carbon emissions and improve the economy of system operation.
