As an attractive large-scale clean energy storage technique, Advanced Adiabatic Compressed Air Energy Storage (AA-CAES) can store and generate both electricity and heat, which has great application potentials in Integrated Electricity and Heating Systems (IEHSs). However, few studies have been reported on Combined Heat and Power (CHP) dispatch by implementing AA-CAES in IEHS. This paper presents a CHP dispatch model considering the participation of AA-CAES for IEHS and mitigating wind curtailment. The mathematical model of AA-CAES for CHP dispatch is developed based on Mixed Integer Linear Programming (MILP). The off-design characteristic of AA-CAES is considered in the modelling process. The benefits of AA-CAES for mitigating wind curtailment and decreasing operation costs in IEHS has been studied. The scheduling analysis based on the developed model and the existing model without considering off-design characteristics has been carried out. The study shows that the participation of AA-CAES in CHP dispatch can increase the flexibility of IEHS, and it can lead to an apparent reduction of wind curtailment and operation costs. Also, AA-CAES's off-design conditions need to be considered in the dispatch; otherwise it can cause the misjudgment of AA-CAES's state of charge, which in turn results in costly operation.
