Bi-level low-carbon optimal dispatch of integrated energy system considering adaptive carbon price and low-carbon demand response

To address the insufficient exploration of low-carbon dispatch potential in integrated energy system and traditional fixed carbon prices struggle to adapt to dynamic fluctuations in energy supply and demand. This paper proposes a low-carbon dispatch strategy for integrated energy system that accounts for adaptive carbon price and low-carbon demand response. Firstly, a concentrating solar power plant is integrated into the integrated energy system. Utilizing its energy time-shifting capabilities, drive energy structure restructuring. Secondly, consider the impact of low-carbon demand response on the load and the user side, using the dynamic carbon emission factor as a guiding signal to measure the correlation between unit power consumption and carbon dioxide emissions. Finally, an adaptive carbon price model is proposed, which sets a carbon emission threshold as the judgment condition. Based on the deviation between carbon emissions and the threshold, the carbon price is adjusted reasonably within a predefined range. Simulation results show that, the proposed dispatch model can further reduce carbon emissions by 6.18% and lower comprehensive operating costs by 1.96%.
