“…In the studies by Zheng et al (2015) and Sanjari and Karami (2020), the optimal dispatching method on the strength of model predictive control (MPC) and the optimal battery storage and energy release condition scheduling strategy grounded on the prediction error are proposed for the IES containing battery energy storage, which in turn optimizes the energy scheduling of the IES. In the studies by Wang et al (2020) and Wang et al (2021), low-carbon IES architecture with hydrogen energy storage as an energy hub was studied to verify the feasibility of two-stage optimization and low-carbon dispatch. However, compared with the energy storage methods mentioned earlier, the advantages of AA-CAES with long service life, low operating cost, and multi-energy co-sourcing (Zhang et al, 2021) can better meet the demand for IES.…”

Advanced adiabatic compressed air energy storage (AA-CAES) is a promising form of CAES technology, which can realize multi-energy cascade storage and supply. Given the characteristics of cooling, heating, and power (CHP) load demand of regionally integrated energy system (IES) and the overall need to control the total carbon emission, this study first establishes the AA-CAES multi-energy storage model; second, based on analyzing the multi-energy characteristics of AA-CAES, a ladder-type carbon trading mechanism is introduced; furthermore, aiming for minimal system operating costs and carbon trading costs, an optimal dispatch model of an integrated energy system with AA-CAES as the energy hub for coupling multiple energy forms is established. Finally, an empirical study was conducted based on the energy use scenario of a provincial and ministerial university in Qinghai Province. This study analyzes the impact of the operation of AA-CAES and the introduction of ladder-type carbon trading on the operating costs and carbon trading costs of IES. The simulation results show that the total operating cost of the proposed model is reduced by 23.9%, and carbon emission is decreased by 14.5% compared to the conventional IES. It proves the validity of coupling AA-CAES and stepped carbon trading mechanisms to facilitate low-carbon economy in IES.
