Understanding and quantifying the inertia of power systems with the integration of converter-
interfaced generation (CIG) plays an essential role in the safe transition to a future low …

Several studies show that grid-integrated renewable energy (RE) sources have the potential
to replace conventional synchronous generators in the network. This means the grid will …

By integrating a significant amount of renewable energy sources such as wind power and
photovoltaic, the power system is gradually evolving into a low-inertia power system. The …

This paper proposes an on-line estimation method able to track the inertia of synchronous
machines as well as the equivalent, possibly time-varying inertia from the converter …

The worldwide motivation to use renewable energy sources and power electronics
interfaced electric drive loads has not only reduced the power system inertia constant but …

Accurate inertia estimates and forecasts are crucial to support the system operation in future
low-inertia power systems. A large literature on inertia estimation methods is available. This …

Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

为了便于风电机组参与一次调频, 提出了一种基于分段频率变化率(ROCOF)
的风电机组一次调频自适应控制方法. 将ROCOF 分为3 个区间, 在ROCOF …

虽然基于系统辨识的惯量在线评估方法可以在线评估电力系统惯量, 但是目前无法确定最佳的
模型阶次, 导致误差较大. 为提升惯量在线评估的准确性, 首先对电力系统正常运行条件下的实测 …

The refined estimation of inertia can provide a reliable basis for power system operation and
control. In this article, a data-driven approach for the estimation of inertia is proposed, and it …
