英文摘要:

      In order to improve the absorption capacity of high-penetration new energy power generation, promote the optimal allocation of energy and reduce carbon emissions, an economical low-carbon optimal scheduling method of integrated energy system based on heat-electric-gas-hydrogen-carbon coupling and source-charge dual response mechanism is proposed. Firstly, a comprehensive energy system model with heat-electric-gas-hydrogen-carbon coupling is established. Secondly, a flexible dual response mechanism of thermoelectric hydrogencarbon coupling is proposed, that is, on the source side, carbon collecting devices are installed on the source side of carbon emission to reduce carbon emission, heat storage devices are installed to absorb waste heat, waste heat boilers are used to generate electricity or hydrogen, and the surplus energy of new energy is used for electricity storage, heating and hydrogen production during the load valley period.And on the load side, the demand response of transferable load and interruptible load is implemented. Then, the green certificate low-carbon economic scheduling strategy based on carbon paving equipment and cascade carbon trading is constructed. Finally, an integrated energy system in North China is taken as an example to demonstrate the advantages of the proposed method.
