RestoreGrid4RES - Strategien und Operator-Tools für den Netzwiederaufbau bei hohem Anteil erneuerbarer Erzeuger

"The massive installation of renewable energy sources will change today’s grid restoration strategies significantly."

Project background

The growing contribution of renewable energies and the liberalized energy market result in higher system stresses in terms of increasing system loadings and fluctuations.

Combined with a delay of grid enhancements this results in an increasing risk of wide-area blackouts and a threat for successful grid restoration.

Project summary

RestoreGrid4RES investigates new grid restoration strate-gies to ensure a fast, coordinated and stable system restoration.

In particular, RestoreGrid4RES gives recommendations whether and how renewable generators shall contribute to the restoration and which technical requirements must be met observing the fact that the vast majority is connected to the distribution systems without direct control by the transmission system operators.

To support grid operators during this difficult procedure, a demonstration tool is developed which shall guide the operators through the restoration process and give helpful information about possible next steps and their consequences.
