英文摘要

      In order to realize the low-carbon economy operation and energy efficient utilization of park-level integrated energy system, an optimal dispatch model of park-level integrated energy system is proposed, in which the exergy efficiency and flexible double response of supply and demand are both considered. Firstly, a low-carbon emission reduction method of park-level integrated energy system based on exergy efficiency is proposed. This method has strong constraint on carbon emissions and no parameter setting problem, and can achieve the double goals of reducing carbon emission of system and decrease energy quality loss. Secondly, considering the supply-side response and the demand-side response in the system, the two will be combined with exergy efficiency for collaborative optimization to improve the flexibility of system operation. Then, with the objective function of reducing the system operation cost and improving the exergy efficiency, an economical, low-carbon and high-efficiency park-level integrated energy system optimization dispatch model is proposed. Finally, the effectiveness of the proposed model is verified by setting up several running scenarios. The results show that the model can take into account the economy, low-carbon and high-quality energy utilization of the system, which can provide a reference for the low-carbon economy dispatch operation of park-level integrated energy system.
