A new framework to facilitate the use of node-breaker operations model for validation of planning dynamic models in WECC

Power Systems Operations and Planning departments historically use different models. Online operations models are based upon node-breaker representation of the system whereas offline planning models are based on bus-branch representation of the same system. Use of different models to represent the same power system leads to discrepancies in data and makes it difficult and inefficient to validate the dynamic models used in short and long term planning for different operating conditions. This paper summarizes a new framework developed by WECC, Peak Reliability and General Electric to facilitate the use of the node-breaker operations model for validation of planning dynamic models used in the western interconnection of United States using GE PSLF.
