LSEissuestoresolve
Many models used in WECC
> Which should be used?
> Which are proprietary only?
> Where do we get it?
Converting model to that used by LSE
Using the LSE outside of .net environment
Keeping topology consistent – Synchronizing data with topology
> SCADA reports are not synchronized with phasors
> How do we get breaker updates for historical data and synchronize with phasor data?
> Same for real-time data?
Choosing the best data (modeless or model based)
