Modeling,simulation and dynamic analysis of the energy stage of advanced adiabatic compressed air energy storage system
摘要
Abstract
Energy and environment problems are becoming increasingly prominent,renewable energy is developing rapidly,and its intermittency is one of the key problems restricting its development.Advanced adiabatic compressed air energy storage(AA-CAES)is an effective method to address the intermittency of renewable energy.In this study,a mathematical model for the energy storage stage of AA-CAES is established,and dynamic and sensitivity analysis of the conservation of energy,energy balance,and key parameters of each component are conducted.The results reveal that the proposed mathematical model follows the laws of conservation of energy and exergy balance;the exergy loss of the compressor is greater than that of the heat exchanger;energy and heat are mainly stored in heat transfer oil and high-pressure air,respectively;the deviation between compressor operating and design condition reduces the efficiency;the effect of the air flow rate and inlet temperature of the first-stage turbine on the operation time is greater than that of the storage temperature,adiabatic efficiency and stored air mass.This paper provides reference for adjusting parameters and optimizing energy storage system according to actual demand.关键词
