Bridging the gap between operation and planning models in WECC

WECC groups and vendors work closely together toward development of new tools and procedures to ensure consistency between the two major models used in WECC, (West-wide System Model (WSM) used by Reliability Coordinators and planning basecases used to perform operational and planning studies), This work includes program features that enable traditional software to read a node-breaker power flow snapshot from WSM, perform different types of system studies, link this model to the WECC dynamic model database and perform dynamic simulations from real-time snapshots and for historical system events to validate the model. Results are compared to actual measurements obtained from phasor measurement units (PMUs). This paper shows some of the results.
