15 New SCADA/EMS SCADA features 2. Sequence control (Bay & Line switching) Bay switching Line switching

16 New SCADA/EMS SCADA features 3. PST Divača regulation

17 New SCADA/EMS SCADA features 4. Enhanced Network Visualization (combined busbar coloring)

18 New SCADA/EMS SCADA features 5. Enhanced Network Visualization (disconnected line coloring)

19 New SCADA/EMS SCADA features 6. Inadvertent island creation

20 New SCADA/EMS Generation application features LFC operating modes

21 New SCADA/EMS Network application features 1. EMS model size does matter TSO

22 New SCADA/EMS Network application features 2. Var Voltage Control (VVC) VVC is fully integrated app for grid voltage profile optimization Supports control of individual generators, transformers and other voltage regulating devices Different objective functions considering multiple constraints (GCC, min and max voltages, voltage changes ) VVC set-points via SCADA to regulating devices Challenges: Stable and reliable SE results is precondition VVC algorithm has to reliably converge to feasible solution Secure gris operation must not be jeopardize by VVC Additional procedures has to be developed in case feasible VVC solution is not available (manual intervention)

23 New SCADA/EMS Challenges SCADA/EMS challenges Communications Power system visualization (alarming hierarchy) Sequence control (TR) LFC modeling EMS modeling Stable & reliable SE results EMS model maintenance Unification of control system database and Operators Manual Instructions to operate

24 New SCADA/EMS Challenges Conclusion Fully customized solution Business needs Development needed Significant risk Difficult maintenance Risky upgrades Standardizes solution Vendor s practice Available solutions Minimal risks Standard maintenance Proven procedures Find a common goals and benefits of both worlds
