Abstract

Abstract: Aiming to facilitate a high penetration of renewable energy power generation and utilization level of the clean energy at the demand side， there is significant development of low-carbon building microgrids integrated with renewable energy power generation. However， renewable energy power generation is usually intermittent， which induces power mismatches between power demand and supply for the building microgrids. Therefore， a method for an office building microgrid is proposed to smooth the tie-line power by scheduling the virtual energy storage system of the building and the electric vehicles at two different time scales. Numerical studies demonstrated that the proposed method can fully utilize the flexibility of the user-side electric vehicles and energy storage system， and effectively smooth the fluctuations of the tie-line power for the office building microgrid.

Key words: building microgrid, renewable energy power generation, electric vehicles（EVs）, tie-line power smoothing
