13 Classical solution: investments SAVE - Active Grid Management at Fluvius 19 september

14 Flexible solution: Active Power Curtailment SAVE - Active Grid Management at Fluvius 19 september

15 Active power curtailment Curtailability doesn t necessarily imply curtailment. Automatic curtailment By using algorithms on central DMS system in combination with telecontrollable assets When reaching network limits Used for congestion on distribution cables or upstream Also for temporary limitations: during N-1 on TSO connection or higher Allows to Operate closer to system (DSO/TSO) limits Install more than in static calculation methods Maximize green generation In situations of degraded system Based on real-time calculated capacity limits SAVE - Active Grid Management at Fluvius 19 september

16 Results of pilot project SAVE - Active Grid Management at Fluvius 19 september

17 Overview Basic Principles Pilot project Waaslandhaven Exploring the limits Conclusions

18 Extending the cable limits Physical limit of cables is temperature based Dynamic Line Rating Real-time temperature measurement Heating of cables has a time delay Use this delay for additional capacity SAVE - Active Grid Management at Fluvius 19 september

19 Infrastructure in the Waaslandhaven WT Measurement of the temperature by means of a glass fibre along the PA50 Modulating the active power of the WT based on the current Congestion point (CP) = Current measurement on the PA50 SAVE - Active Grid Management at Fluvius 19 september

20 Measuring the temperature Determine the critical hot spots Determine the potential of Dynamic Line Rating SAVE - Active Grid Management at Fluvius 19 september

21 Calculating the temperature Blue = calculated temperature Red = measured temperature Calculating the temperature based on the measured current SAVE - Active Grid Management at Fluvius 19 september

22 Application of the results efficient use of existing assets Avoid curtailment of short power peaks Avoid over-investment for short power peaks Take care of critical hot spots SAVE - Active Grid Management at Fluvius 19 september

23 Reactive Power Control Voltage Control on distribution lines Optimize operating point on TSO connection Allows to deliver Reactive Power as ancillary if needed SAVE - Active Grid Management at Fluvius 19 september

24 Overview Basic Principles Pilot project Waaslandhaven Exploring the limits Conclusions

25 Conclusions Active Grid Management in the MV-grid has potential: Allowing more green energy on the grid Helping to exploit the existing assets closer to their limits Delivering ancillary services when needed Fluvius (Eandis) is extending the results: By using the same principles elsewhere By identifying new opportunities where possible SAVE - Active Grid Management at Fluvius 19 september
