Abstract

As levels of wind, photovoltaics (PVs), and battery energy storage on power systems rise, it is useful to be able to quickly compare how much generation (instantaneous power and annual energy) comes from these inverter-based resources (IBRs). A commonly used metric is the percentage of inverter-based generation (% IBR) in a dispatch scenario (as a percentage of the total generation or total load), which can be useful for estimating when certain operational challenges arise (high rates of change of frequency, underdamped control interactions, low system strength, low fault current availability, and so on). Another similar and commonly used metric pioneered on the relatively large island of Ireland, system nonsynchronous penetration (SNSP), is similar to the % IBR and is subject to similar limitations. SNSP has the advantage of handling high-voltage dc in a defined way.

基于逆变器的孤岛系统稳定性指标与需求的思考与假设[观点]

随着风能、光伏(pv)和电力系统电池储能水平的提高，能够快速比较来自这些基于逆变器的资源(IBRs)的发电量(瞬时功率和年能量)是有用的。一个常用的度量是调度场景中基于逆变器的发电量的百分比(% IBR)(占总发电量或总负载的百分比)，这对于估计何时出现某些操作挑战(高频率变化率、欠阻尼控制交互、低系统强度、低故障电流可用性等)非常有用。在相对较大的爱尔兰岛上开创的另一个类似且常用的指标是系统非同步渗透(SNSP)，它与% IBR类似，也受到类似的限制。SNSP的优点是能以固定的方式处理高压直流电。

期刊介绍： IEEE Electrification Magazine is dedicated to disseminating information on all matters related to microgrids onboard electric vehicles, ships, trains, planes, and off-grid applications. Microgrids refer to an electric network in a car, a ship, a plane or an electric train, which has a limited number of sources and multiple loads. Off-grid applications include small scale electricity supply in areas away from high voltage power networks. Feature articles focus on advanced concepts, technologies, and practices associated with all aspects of electrification in the transportation and off-grid sectors from a technical perspective in synergy with nontechnical areas such as business, environmental, and social concerns.
