SASKPOWER OPEN ACCESS TRANSMISSION TARIFF

SASKPOWER OPEN ACCESS TRANSMISSION TARIFFvoltages shall be within SaskPower post-contingency limits. Automatic systems mayinclude capacitor or reactor insertion schemes, phase shifter tap-back or DC converterstation run-back, automatic generation control or other schemes, but would not includeany operator initiated system adjustments that are implemented.Base Conditions for Simulation StudiesPowerflow models used for system impact studies are constructed from the most recent MAPPpowerflow series available at the time the study is commenced. The MAPP powerflow seriescontains models that represent the SaskPower and MAPP systems in detail in the short, near andlong-term time frame (approx. 1 to 10 years). Transfers to Alberta are currently modeled usingload and/or generation at the 230 kV bus of the McNeill HVDC back-to-back converter station.A detailed model of the Alberta system (Alberta Interconnected Electric System) is not containedin the powerflow models. The Alberta system (which is part of the Western Interconnection)operates asynchronously with SaskPower (part of the Eastern Interconnection) via the converterstation.Page | 119
