Abstract

To address the limitations of traditional carbon sharing mechanisms, which often overlook the additional emissions caused by the uncertainty of renewable energy generation, this paper puts forward a novel bi-level method aimed at achieving low-carbon dispatch in integrated energy systems. The strategy accounts for both renewable energy carbon responsibility sharing and the synergistic effects of various demand responses. Firstly, on the supply side, a stochastic optimization method based on scenario comparison is used to quantify the additional carbon emissions induced by renewable energy fluctuations. Secondly, an improved Shapley value-based approach is employed to allocate the residual carbon responsibility to load-side entities and to design a differentiated dynamic tiered carbon pricing mechanism, thereby addressing the combinatorial explosion problem arising from multiple stakeholders. Then, carbon pricing is combined with energy pricing to guide low-carbon demand responses on the load side, maximizing the carbon reduction efficiency of users. Finally, simulation studies on an integrated energy system with electric-thermal coupling verify the effectiveness of the proposed approach. The results indicate that the method accurately allocates carbon emission responsibilities among stakeholders. Moreover, the proposed dispatch strategy achieves a coordinated balance between carbon reduction and economic performance by effectively lowering emissions without compromising system cost-effectiveness.
