10 Summary and Next Steps Summary Changes in Energy Supply may result in increased importance of transient phenomena also in the control center DynaGridCenter provides a test bed for the implementation of new algorithms on station as well as control center level to handle those transient phenomena A set of algorithms on control center as well as station level are about to be implemented together with relevant test scenarios. Next Steps Commissioning of Simulator with Network Model Definition of Scenarios and measures for algorithms Implementation of Algorithms (control center / station) Page 10
