Low-Carbon Economic Dispatch in Integrated Energy Systems Utilizing Chalcogens

Researchers at Nanchang University have made significant strides in addressing the problem of underutilized oxygen in power-to-gas (P2G) technology, a crucial component in achieving a low-carbon economic dispatch in integrated energy systems. The P2G process converts electricity energy into natural gas, playing a vital role in reducing carbon emissions. To optimize the system, the researchers proposed a low-carbon integrated energy system that considers P2G oxygen-enriched improvement and combined solar energy utilization. The system handles carbon reduction from three aspects: mixing oxygen produced by P2G with CO2 as an assistant combustion gas, utilizing captured CO2 to produce natural gas for gas-fired units, and improving solar energy efficiency by using mixed solar energy to reduce fossil energy use.
