同步发电机（SGs）由于其提供系统强度和惯性的固有能力，在电压/频率扰动后对电力系统的重新稳定仍做出重大贡献。然而，由于风力和太阳能的低价异步发电加速增长，由化石燃料驱动的同步发电机运行程度降低，并计划在澳大利亚国家电力市场（NEM）退役，这导致系统强度和惯性降低，在某些情况下甚至出现短缺。本文从运行安全的角度全面综述了国家电力市场对系统强度和惯性的要求。澳大利亚是第一个制定系统强度和惯性监管规则的国家，以应对新兴的高比例非同步可再生能源发电问题。
Synchronous generators (SGs) are still making major contributions to the re-stabilization of a power system following voltage/frequency disturbances, attributed to their inherent capability of providing system strength and inertia. However, SGs powered by fossil fuels are operating to a lesser extent and scheduled for decommissioning in the National Electricity Market (NEM) of Australia due to the accelerating increase of low bidding priced asynchronous generation of wind and solar, which leads to the reduction and even in some cases, a shortage of system strength and inertia. This paper comprehensively reviews the requirements of system strength and inertia in the NEM from an operational security perspective. Australia is the first country that established the regulation rules of system strength and inertia to accommodate issues of an emerging high penetration level of non-synchronous renewable generation.
