Research on Integrated Energy Microgrid Operation Considering P2G and CCS

In order to realize the goals of sustainable energy use and low-carbon economic development, this paper analyzes the operating characteristics of cogeneration units, carbon capture and electricity-to-gas conversion equipment, proposes a combined operation mode of cogeneration units taking into account carbon capture and electricity-to-gas conversion technologies, analyzes the characteristics of the electricity-heat output of the cogeneration units and the carbon emissions under the mode, and establishes an integrated energy microgrid economic operation model under the joint operation mode taking into account the carbon trading. An economic operation model is developed for the integrated energy microgrid considering carbon trading under this combined operation mode. The example verifies the economy and carbon emission advantages of the integrated energy microgrid based on carbon capture and electricity-to-gas conversion technologies under four scenarios, which effectively reduces the carbon emission of the microgrid while minimizing the system operation cost. Compared with the traditional microgrid, the operating cost is reduced by 7776.84 yuan and the carbon emission is reduced by 2697.88 kg.
