TT08 Modelling, operation, control, and stability analysis of low-inertia power systems (Part I)

Abstract

The module discusses the dynamic analysis and operation of low-inertia grids, that grid with high penetration of converter-interfaced generation. The module is organized into two parts. The first part focuses on operation and control, whereas the second part deals with modelling and stability analysis. The module blends industry experience and recent trends in academic research. The industry point of view is represented by EirGrid that operates the Irish grid up to 75% non-synchronous instantaneous power generation and DIgSILENT that will share their experience with the implementation of converter and their controllers in a power system software tool. The academic presentations discuss state-of-the-art concepts on the modelling of security constrained optimal power flow problems for low-inertia systems; as well as recent advances in the synchronization stability and modelling of grid-connected converters and their controllers. All presentations include several illustrative examples based on both benchmark and real-world systems.
