Optimized Dispatch of Integrated Energy System with Hydrogen Energy and Carbon Capture Under Demand Side Response Mechanisms

In order to improve the energy utilization and reduce carbon emissions of the integrated energy system, this paper proposes an optimal scheduling strategy for the integrated energy system including hydrogen energy and carbon capture taking into account the demand-side response mechanism. Firstly, in order to give full play to the efficient and clean characteristics of hydrogen energy on the source side, a heterogeneous energy synergistic operation framework is constructed containing electrolyzer, methanation device, hydrogen fuel cell and carbon capture system, secondly on the load side, a transfer-type and substitution-type demand response model is established, and a wind-carbon/hydrogen/storage low-carbon optimal dispatch model is constructed with the minimum system operation cost and carbon emission. Example analysis shows that the proposed model and method can effectively reduce carbon emissions and improve the stability and economy of the system at the same time.
