LBMP Bus Calculation Method Sample Clauses

LBMP Bus Calculation Method. System marginal costs will be utilized in an ex ante computation to produce Day- Ahead and Real-Time LBMP bus prices using the following equations. The LBMP at bus i can be written as: Where: = LBMP at bus i in $/MWh = the system marginal price at the Reference Bus = Marginal Losses Component of the LBMP at bus i which is the marginal cost of losses at bus i relative to the Reference Bus = Congestion Component of the LBMP at bus i which is the marginal cost of Congestion at bus i relative to the Reference Bus The Marginal Losses Component of the LBMP at any bus i is calculated using the equation: Where: = delivery factor for bus i to the system Reference Bus and: Where: = injection at bus i The Congestion Component of the LBMP at bus i is calculated using the equation: Where:

Substituting the equations for and into the first equation yields: LBMPs will be calculated for the Day-Ahead and the Real-Time Markets. In the Day-Ahead Market, the three components of the LBMP at each location will be calculated from the SCUC results and posted for each of the twenty four (24) hours of the next day. The Real-Time LBMPs will be calculated and posted for each execution of RTD.

LBMP Bus Calculation Method. System marginal costs will be utilized in an ex ante computation to produce Day- Ahead and Real-Time LBMP bus prices using the following equations. Where: The LBMP at bus i can be written as: γi = λR + γLi + γCi γi = LBMP at bus i in $/MWh λR = the system marginal price at the Reference Bus γ L = Marginal Losses Component of the LBMP at bus i which is the marginal γ C = Congestion Component of the LBMP at bus i which is the marginal cost of the equation: Where: γ L = (DFi - 1) λR DFi = delivery factor for bus i to the system Reference Bus and: Where: DFi = ( 1 - ) ∂Pi L = NYCA losses; and Pi = injection at bus i The Congestion Component of the LBMP at bus i is calculated using the equation: c  n  γ = − ∑ i  k∈K GFik μk  , except as noted in Sections 17.1.2.2.1 and 17.1.2.3.1 of this Attachment B Where: K = the set of Constraints; GFik = Shift Factor for bus i on Constraint k in the pre- or post- Contingency case which limits flows across that Constraint (the Shift Factor measures the incremental change in flow on Constraint k, expressed in per unit, for an increment of injection at bus i and a corresponding withdrawal at the Reference Bus); and
