Integrated energy optimization dispatch considering demand response with P2G and carbon capture and hydrogen blending

In order to achieve the goals of "peak carbon emissions and carbon neutrality", the flexibility of the source side of the integrated energy resource system is enhanced, coupled with multiple demand responses from various load sides. To this end, an integrated energy resources system (IES) with electric to gaseous and carbon catch (P2G-CCS) connection and hydrogen doping has been established. Firstly, the project takes the P2G-CCS connection and gas hydrogen blending as the research object, and constructs a hydrogen doping gas system. At the level of deep low-carbon economic optimization, multiple devices are mathematically modeled; based on the above, an optimization scheduling method for a gas hydrogen mixed gas electric coupled system is proposed. Step carbon trading and demand response mechanisms enable the rapid adjustment of users' energy consumption, which relieved the pressure on energy supply during periods of concentrated load. Lastly, the experiment sets up several scenarios for comparative analysis, and simulation results verify the model with splendid performance. Changes in hydrogen doping proportion and hydrogen doping approach influence the economic performance of low-carbon IES.
