摘要: 为促进高比例可再生能源在用户侧的有效集成,提升用户侧清洁能源利用水平,融合可再生能源发电的低碳楼宇微网技术得到了快速发展。然而,可再生能源发电通常具有间歇性,易使楼宇微网存在供需不平衡问题,进而导致微网联络线功率频繁波动。为此,文章提出了一种用于办公楼宇微网联络线的功率平滑控制方法,在2个不同时间尺度上对楼宇虚拟储能系统和电动汽车(electric vehicles, EVs)进行优化调度,从而实现对联络线功率波动的有效平抑。算例结果表明,该方法可充分利用用户侧电动汽车和虚拟储能系统的灵活性,有效平抑办公楼宇微网的联络线功率波动。

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
