Nadir Frequency Estimation in Low-Inertia Power Systems [PDF]

2020 IEEE 29th International Symposium on Industrial Electronics (ISIE), 2020
Increasing amounts of non-synchronous generation in power grids are bringing reductions in system inertia. In a grid with extremely low inertia, the estimation of frequency indicators such as the frequency nadir can be used to feed into predictive system controls that would avoid nuisances such as triggering system protection systems, avoiding needless

Prediction of Frequency Nadir by Employing a Neural Network Approach [PDF]

2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018
Ahstract- The increased integration rate of inverter-interfaced devices is affecting the frequency response of the modern power systems. This leads to an increase of the variability of the power generation and to a reduction of the total system's inertia.

An Analytical Model for Frequency Nadir Prediction Following a Major Disturbance

IEEE Transactions on Power Systems, 2020
The frequency nadir is a significant indicator for the primary frequency response monitoring and control. It is imperative to predict the maximum frequency deviation and the time at which the maximum occurs with high efficiency and accuracy following a major disturbance. To develop an analytical model for the frequency nadir prediction, the closed-loop
