Power Flow Features

Multi-limit Modeling for Capacitors

This feature adds the ability to model the position of capacitors based on multiple limits associated with it.

This feature adds support for normal and emergency limits for capacitors, and also adds support for a date range limit type. Previously, NMS only supported a single limit set. The limit types supported now are:

• Fixed

• Switched

• Voltage

• Current

• Time of day

• kVAr

• Temperature

• Date range

The emergency limit, if met, overrides the normal limit.

The normal control mode can be a combination of

• Up to three normal limits using the operator AND

• Or, two normal limits using the operator OR

PF Service Performance Enhancements

This feature improves the performance of the PowerFlow service (PFService), so that other enhancements related to DERMS and forecasting are feasible in NMS.

This feature reduces bottlenecks in the PFService and better leverages multi-core architecture on modern computing platforms.

PFService has been updated to work in a more multi-threaded fashion.
