Modeling

The modeling group creates and maintains the power flow models that are used by the Transmission Planning and Tariff Studies groups. They continuously coordinate data with members to ensure the models' accuracy: a critical step in making investments in our region's transmission grid.

The Modeling group introduced Model On Demand (MOD): a concept to develop power flow models. This is a new tool through which SPP members update their models via web-based applications, making the modeling process more efficient. This group also makes system-loss calculations, maintains SPP transmission maps and represents SPP on various national and subregional committees that conduct joint planning studies. The data created and reported by the Modeling group is stored on this website or in TrueShare, a website for file and correspondence exchanges.

Per NERC Standards MOD-026-1 & MOD-027-1, the Generator Owner (GO) or Transmission Owners (TOs) must request data and data formats from their Transmission Planners (TPs) so that proper testing and exchanging of data of and for exciters and governors can be performed for their facilities meeting the standards requirements. The coordination of data exchange and certain Market protocols is imperative to ensure that there are no missed expectations on either the GO/TO or the PC part. SPP has created a FACTs document (located in the sidebar under "related documents") that encompasses the needs of SPP engineering and operation sides of the business.
