Abstract：Aiming at the problem of mismatch between clean energy and users'energy demand fluctuations in the current building microgrid,a new optimization method for building microgrids based on the demand-side dual-layer virtual energy storage management framework is proposed.During the recent dispatching stage,the upper structure is constructed.Based on the thermal balance equation and the temperature range of human comfort,a virtual energy storage model for the building is established.During the intraday dispatching stage,the lower-level structure is constructed and incorporated into the electric vehicle energy storage model.By integrating a dual-layer virtual energy storage management system,with the goal of minimizing the daily comprehensive operating cost of the system,different operation modes of the building microgrid are analyzed.The results show that this method can improve the energy utilization efficiency of the system and achieve an efficient match between clean energy and user demands.
