Energy Efficiency Optimization of Integrated Energy System Considering Carbon Emissions

With the increasing of energy consumption, it is important to improve energy efficiency and reduce carbon emissions. Integrated energy system can effectively improve energy efficiency by coupling multiple energy sources. In order to further improve energy efficiency and reduce carbon emissions, this paper proposes an energy efficiency optimization model with power to gas system (P2G). The energy supply cost and overall energy efficiency of integrated energy system are improved by hybrid energy storage system, which increases the system's wind power consumption rate by 11.2%. And the optimization strategy proposed in this paper increases the total energy efficiency of the system by 7.3% and reduces the total carbon emissions by 15.1%.
