【Abstract】 To control carbon emissions due to energy consumption and to achieve the objectives of carbon peaking and carbon neutrality, a step-by-step carbon-trading mechanism is proposed that considers carbon offsets. Additionally, the economic and environmental benefits of using natural gas pipelines to generate electricity were considered based on the complementary characteristics of multiple energy sources, such as electricity, heat, and gas, and the principle of energy cascade utilization. A low-carbon economic optimization scheduling model was developed for an integrated energy system of electricity-heat-gas cogeneration, and a case study was performed. First, a carbon-trading mechanism that included carbon offset was established, with the environmental cost incorporated into the system economic optimization target. Subsequently, a power generation model utilizing the pressure of natural gas pipelines was developed using the exergy analysis method, while relevant constraints were determined by combining other unit output and energy transmission network models within the system. The aim of minimizing the operating cost of the system and reducing carbon emissions was achieved by developing an overall framework for the integrated energy system, and low-carbon economic optimization scheduling was conducted based on the case study. This approach reduces the operating cost of the system, energy consumption, and carbon emissions. Furthermore, it prevents the adverse effects on the upstream power grid caused by the fluctuations in power demand.更多还原
