Abstract

Driven by the dual strategy of “double carbon” target and energy transformation, this paper proposes a synergistic optimization model of integrated energy system integrating photovoltaic power plant, stepped carbon-green certificate trading mechanism and load demand response, and puts forward an innovative solution to improve the economic and environmental benefits of the integrated energy system. First, on the basis of the traditional integrated energy system model, a model of the concentrating solar power（CSP） plant is constructed, and the stepped carbon-green certificate trading mechanism is introduced. Second, the demand response model of electric and thermal loads is constructed, and the system is analyzed in accordance with the energy quality characteristics, and the exergy efficiency model of the whole system is constructed. Finally, the model is solved using a hybrid optimization algorithm of Aquila Eagle and African Vulture. The results show that the optimization model proposed in this paper reduces the total system cost by 37.62%, reduces the carbon emission by 43.76%, and improves the energy efficiency by 14.72% compared with the traditional model.
