  1. SCED Penalty Factor Resmi Surendran

  2. Transmission Constraint Penalty Values Maximum Shadow Price for • Base Case:  $5,000/MW • Generic constraints :  $5,000/MW • Post Contingency • 345 kV:  $4,500/MW • 138 kV:  $3,500/MW • 69 kV:  $2,800/MW

  3. Power Balance Penalty Curve • equivalent to having extra capacity for meeting power balance violation at • (+/-) 3001 $/MWh for violated MW from 0MW to 9999.999MW, and • (+/-) 5000$/MWh for violated MW from 10000MW to 99999.999MW

  4. Effects of Different Power Balance Penalty Curve • Scarcity Pricing • Effects on reliability due to dependence on regulation

  5. Study • Parameters • Energy Offer Curves from LFC test date • W_N, N_H & Valley interfaces as competitive constraints • Generation pattern & transmission constraint flows at different load levels. • Monitor • Max/Min/Avg LMP & SPP • Amount of Power Balance violation & dependence on regulation

  6. Shift Factor Cut off • SF cut off • during LFC test was 0.03 • for Nodal is 0.0001 • Effective SF cut off in Nodal => Offer Cost / Max Shadow Price • 0.03 SF => 1 MW generation will provide 0.03 MW relief or 33.33 MW of generation needed • to provide 1 MW relief • Will cost (1/SF) * offer cost • Max cost Market is willing to pay is the Max Shadow Price for the constraint
