Design of Green Building Energy Microgrid Based on Compressed Air Energy Storage

With the widespread application of renewable energy and the increasing demand for energy efficiency, green building energy microgrids have become the key to sustainable development. This article proposes a green building energy microgrid design scheme based on compressed air energy storage (CAES). As an energy hub, CAES fully leverages its advantages of multi energy combined reserve and supply. Based on the energy flow distribution of the CAES system,it analyzes the operating modes in different seasons under the demand for cold and hot loads. At the same time, a CAES and fresh air system integration method was proposed, which can improve the energy utilization efficiency of the system, optimize the quality and controllability of fresh air supply. This study can provide certain reference value for the practical application of green building energy microgrids.
