Region Of Stability Existence (ROSE) – Online Advanced Applications
V&R Energy’s SCADA-based platform is shown in the figure below.
V&R Energy’s SCADA-based analysis platform includes:
- Fast robust load flow
- Real-time contingency analysis (RTCA)
- Voltage stability analysis
- Power transfer analysis
- Transient stability analyses
- Small-signal stability analysis
- Automated creation of power flow cases based on various forecasts
- Real-time phase angle limit computation and monitoring
- Automatic analysis of cascading outages
- Automatic remedial actions
- Boundary-based solutions
It can use V&R Energy’s State Estimator or export from any other EMS vendor in node breaker or bus-branch format.
