论文摘要
对于可持续能源的未来，必不可少的可再生能源与电网相结合。但是，基于逆变器的资源（IBR）的渗透增加减少了网格惯性，这可能会损害电源系统的可靠性。因此，电力公用事业通常有兴趣确定其系统的最大IBR渗透限制。拟议的研究提出了一种方法来确定IBR穿透阈值，超出该阈值，将超出电压，频率和平局限制。还分析了IBR穿透阈值对瞬时停止，由于电压低，透射与分布连接的太阳能产生以及引导电动机停滞的敏感性。对西方互连（WI）进行了24,000个总线模型进行的动态仿真研究证明了该方法的实用性。
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.
