Schedules - allow 3 values per time point
Context: how to use IEC 61850 for DER and microgrids (IEC 61850-90-23 CD1).
Several use cases require schedules or forecasts that have several values for each time point.
- Forecast quantities with nominal, lower bound and upper bound values
- Preferred (ideal) setpoint, minimum and maximum limits
- Operational function set point values and activation modes
Today this is only possible by using several FSCH logical nodes. This has the risk that communication failures may leave the set of FSCH nodes with inconsistent information.
This would also help with mapping to CIM based systems.
