The availability of a sufficient amount of inertia is important to guarantee stability of the electric power system. Nowadays, this inertia is provided by grid-synchronous rotating masses. In the context of this background the provision of synthetic inertia provided by hydro power units is investigated. Such units provide additional inertia by means of a converter coupling the units to the grid. The system concept of such units is introduced and the technical limitations are discussed. Finally, a possible market approach for the ancillary service “inertia” is presented.
