Integrated energy optimization strategy based on advanced adiabatic compressed air energy storage

As the most promising energy storage technology at present,the Advanced Adiabatic Compressed Air Energy Storage (AA-CAES) can promote the regional integrated energy system to absorb new energy,make efficient use of traditional energy,and reduce environmental pollution. Here,an energy supply optimization strategy for regional integrated energy system is established with the AA-CAES,which can reduce the operation cost of the system in its daily cycle. First,we analyze the energy storage characteristics of the AA-CAES,the electric power balance as well as the thermal power balance of the regional integrated energy system,and the operation constraints of different energy suppliers. Then we use optimization software of GAMS to solve the operation cost of traditional regional integrated energy system and the proposed strategy in their daily cycles. Finally,the comparison in aspects of environmental protection and economic cost verifies the effectiveness and feasibility of the proposed strategy in reducing cost,promoting new energy consumption,and energy conservation & emission reduction.
