Advanced decision support for operation of converter-dominated grids with low inertia utilizing a modular development and testing framework

The world-wide energy transition results in a shift from conventional grid structures and assets towards a converter-dominated grid structure. Beyond the energy-balancing task, there are several additional challenges for power-system operation and control. These arise especially from the reduction of directly connected inertia and from the characteristics of controlled converters. Together, these factors determine stability risks and influence system dynamics that are not covered by conventional, market-available grid-control and decision-support products.
