Abstract
With growing public awareness of decarbonization and increasing penetration of renewable generation, energy storage is in great need. Advanced adiabatic compressed air energy storage (AA-CAES) is capable of producing power, heating and cooling, making it an ideal choice of an environmental-friendly energy hub. This paper proposes an energy and exergy efficiency analysis for an AA-CAES based trigeneration energy hub. Impact of power storage and heat load supply rates on energy output efficiency and total exergy losses are analyzed. Based on the proposed model, optimal configuration of power storage and heat load supply rates can be determined under different purposes. According to basic thermodynamic principles, the proposed method calculates trigeneration capability estimates considering energy grade difference and multi-dimension energy distribution, which can demonstrate more energy conversion properties of the system. Case studies verify that the proposed method can provide various characteristic analyses for an energy hub and its application in actual systems proves computation accuracy. Integrative energy efficiency is improved compared to pursuing maximum electricity-to-electricity efficiency.
