非同步发电机的日益普及，伴随着同步发电机的退役/取代，在澳大利亚国家电力市场（NEM）网络中产生了许多新的运营问题，例如低惯性条件。低惯性电力系统在发电/负载不匹配之后可能经历相对大的频率变化。最近在澳大利亚国家电力市场（NEM）电网中发生的事件证明了这一点，该事件导致了连锁故障以及昆士兰州和南澳两个州与NEM的其余部分的电力分离。本文首先对2018年8月25日发生的事件进行了广泛的描述，该事件的高级动态行为在NEM简化测试系统中进行了模拟。其次，使用电网规模的电池储能系统（BESS）在提供主频率响应（PFR）的连锁故障的潜在对策进行了研究。仿真结果表明，BESS可以潜在地避免低频减载（UFLS）。
The increasing penetration of non-synchronous generators, accompanied by retiring/displacement of synchronous generators has created a number of new operational issues in the Australian National Electricity Market (NEM) network, such as low-inertia conditions. Low-inertia power systems are likely to experience relatively large frequency variations following a generation/load mismatch. This is evidenced by a recently occurred event in the Australian National Electricity Market (NEM) grid, which led to cascading failures and electrical separation of the two states of Queensland and South Australia from the rest of the NEM. This paper first provides an extensive description of the event occurred on 25th August 2018, whose high-level dynamic behaviour was simulated in a NEM reduced test system. Secondly, the use of grid-scale battery energy storage system (BESS) in providing primary frequency response (PFR) is investigated as a potential countermeasure to cascading failures. Simulation results show BESS could have potentially avoided under-frequency load shedding (UFLS).
