THE JOURNEY SO FAR A few milestones 1990 Implementation of EMS (three different areas) 2004 Regional control centers merged to one central site 2011 First self healing grid operational (Rotterdam) 2011 Project IDMS started 2016 IDMS fully operational
Self Healing Grid 150 kv TenneT (TSO) Stedin (DNO) EMS 23/25/50 kv 10/13/23 kv Primary Substations: SA based on IEC 61850 and IEC 60870-5-104 protocol (roll out) CB CB DMS (planned) Pilot Projects : FPI s Remote control Self Healing 0,4 kv MV substations: SA based on IEC 61850 and IEC 60870-5-104 protocol (to be developed)

SCADA landscape Centralize intelligence Balancing Control TSO Communication Local and autonomic intelligence Manageability Reduce complexity Customer involved
STATUS TODAY Control distribution grid NOC Operational (incl. fail-over center) EMS/DMS in place (IDMS project) Proces changes implemented: The to be grid configuration uploaded in GIS and DMS before going live Self healing grid in Rotterdam Automatic ring switching at fault situation Loadflow analysis (phase 1) Integrated MV/LV measurements from DMS and started with realtime metering in MV/LVsubstations Sustainable net design DG integrated in design proces 16 Cyber Security First implementation in telecom network
EMS/ DMS FUNCTIONALITY TODAY Complete dynamic network view (schematic, geographic and internal), synchronized with GIS Equipment status & powerflow monitoring Network Outage Management Network Analysis Network Optimization Network View System Simulator Switching Operations Demand response DERMS Fault Isolation and Service Restoration (FISR) Network operations User interface Network operations Model Plan Outage Study (POS) Remote switching planning Remote Switching Call Center Workforce Management Distribution Automation Equipment & Network Models (GIS) Automated Metering (AMI) e-terrascada System Network simulation & analysis Automated analysis impacted customers at outage situation (tracing)
DATACOMMUNICATION INFRASTRUCTURES A VITAL PART OF A SMART GRID Utility owned networks To be in control over performance, cost & speed of innovation Core netwerk (laag 1) Regio Utrecht Fiber IP based network in place: all HV substations # MV substations Stedin owned & operated MPLS planned in 2016 Wireless network (CDMA 450 Mhz) in place to deliver connectivity to: All other MV substations Customer locations (smart meters) Utility Connect owned (JV with Alliander), operated by KPN Operational since May 2015 Regio Rotterdam Regio Dordrecht IP based fiber network CDMA 450 wireless network
Is SCADA future proof? Wrap-up Trends & studies Decentralization More autonomic systems Local produce (local use) Local intelligence is a must Demand response Lokal markets Reliable Manageability
