PI‐Formers: An AI4S Approach for Transient Rotor Angle Prediction in Renewable‐Integrated Power System Under Large Disturbances

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This article proposes a novel methodology for predicting high‐dimensional nonlinear dynamics in power systems, with a focus on rotor angle trajectory prediction. By integrating the Transformer architecture with physics‐informed neural networks, the approach achieves accurate and physically consistent predictions, even with minimal labelled data.

Virtual synchronous generator: Modifications, stability assessment and future applications

Energy Reports, 2022
The distributed generation (DG) integration into the power system is growing rapidly. Therefore, the power system experiencing low inertia and damping because DG possesses no or low inertia causes severe stability issues.

An Overcurrent Suppression Strategy for Distributed Photovoltaic Inverters Under Unbalanced Faults Based on Adaptive Linear Active Disturbance Rejection Control

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
After distributed photovoltaic (PV) systems are connected to the distribution network, the overcurrent problem caused by transient faults instantaneously threatens the safety of PV inverters and other equipment. This paper proposes a comprehensive control method that combines active‐loop adaptive linear active disturbance rejection control (A‐LADRC ...

Frequency Regulation Capability Improvement Control Strategy for Grid‐Forming Direct‐Drive Wind Turbines

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Grid‐forming control of direct‐drive permanent magnet synchronous generator (D‐PMSG) wind turbine is an effective method to improve the frequency stability and provide inertia support for the system. In conventional virtual synchronous generator (VSG)–based grid‐forming control, fixed inertia and droop coefficients can result in poor frequency ...
