考虑AA-CAES系统电热灵活性的电热联合系统实时调度
Real-time dispatch of integrated electricity-heat systems considering the electricity-heat flexibility of AA-CAES systems
摘要
Abstract
Advanced adiabatic compressed air energy storage(AA-CAES)systems are an effective means of enhancing the operational flexibility of integrated electricity-heat systems.However,current research mainly focuses on improving their electricity storage and discharge capabilities while overlooking their bidirectional heat power regulation capability,resulting in relatively low overall energy utilization efficiency.Therefore,a real-time dispatch strategy for integrated electricity-heat systems considering the electricity-heat flexibility of AA-CAES systems is proposed.During the peak of wind power,AA-CAES systems compress air for electricity storage while releasing compression heat to be stored in the thermal storage tank,with surplus compression heat supplied to heat loads.During periods of low wind power output,the AA-CAES system absorbs surplus heat from the system and,together with the thermal storage tank,supplies heat to the expansion process for electricity generation.Furthermore,considering thermal energy transmission delays,a real-time dispatch model of the integrated electricity-heat system incorporating the thermal response delay of the AA-CAES system is established,thereby improving the traditional electricity-heat power balance.Case studies demonstrate that exploiting the bidirectional regulation capabilities of AA-CAES systems in both electricity and heat enables greater decoupling between electricity and heat,thereby significantly enhancing the operational flexibility of the integrated system and its wind power accommodation capability.关键词
