Corrective Congestion Management in Transmission Grids Using Fast-Responding Generation, Load and Storage

Abstract

This paper elaborates a corrective congestion management concept for transmission grids involving fast flexible units and storage systems referred to as “grid booster”. This post-fault remedial action acts as a first temporary relief for congested lines. It enables system operators to trigger subsequent corrective congestion management measures with significant lead times to re-establish an (N-1)-secure system state. This paper covers different aspects of integrating grid booster technologies and configurations into existing operational planning and real-time operation processes.
