Convert calculated system losses calculated by network applications (NA) to market losses for use by SCUC according to the following formula: Convert the NA calculated physical loss sensitivities to a market resource loss sensitivity using the following formula: Convert the NA calculated physical Resource MW base points to the market resource MW base point using the following formula: Modeling Transmission Related Market Attributes The following sections describe market related concepts impacting transmission system modeling in the FNM. Intertie Scheduling Constraints Interties represent the transmission interconnections between the CAISO Balancing Authority Area and adjoining Balancing Authority Areas and are used as the Scheduling Points for imports, exports, and wheeling. Interties or Scheduling Points are also used for wheeling power across a Balancing Authority Area. An Intertie can be used by multiple SCs. Each SC can schedule interchange at multiple Interties. An SC can have multiple interchange schedules at the same Intertie Scheduling Point by assigning a unique interchange identifier to each interchange schedule. With each Intertie there is a requirement to include the following scheduling constraints during the SCUC optimization: Where: I = Total Energy Import E = Total Energy Export R = Total AS Import (total of RegUp, Spin, and NonSpin imports, and RegDown exports) FI = Intertie ATC in the import direction
