动态环境下公用事业规模可再生能源渗透阈值的确定

Identification of Utility-Scale Renewable Energy Penetration Threshold in a Dynamic Setting

Hashem Albhrani, Reetam Sen Biswas, Anamitra Pal

摘要:

可再生能源与电网的整合是可持续能源未来的必要条件。然而,基于逆变器的资源(IBR)的增加的渗透降低了电网惯性,这可能随后损害电力系统可靠性。因此,电力公司往往有兴趣确定其系统的最大IBR穿透极限。拟议的研究提出了一种方法,以确定IBR的渗透阈值超过电压,频率和联络线的限制将被超过。还分析了IBR穿透阈值对由于低电压、输电与配电连接的太阳能发电以及感应电动机失速而引起的瞬时停止的敏感性。通过对西部互联网24,000节点模型的动态仿真研究,验证了该方法的实用性。

英文摘要:

Integration of renewable energy resources with the electric grid is necessary for a sustainable energy future. However, increased penetration of inverter based resources (IBRs) reduce grid inertia, which might then compromise power system reliability. Therefore, power utilities are often interested in identifying the maximum IBR penetration limit for their system. The proposed research presents a methodology to identify the IBR penetration threshold beyond which voltage, frequency, and tie-line limits will be exceeded. The sensitivity of the IBR penetration threshold to momentary cessation due to low voltages, transmission versus distribution connected solar generation, and stalling of induction motors are also analyzed. Dynamic simulation studies conducted on a 24,000-bus model of the Western Interconnection (WI) demonstrate the practicality of the proposed approach.
