LBMP Bus Calculation Method Clause Samples

The LBMP Bus Calculation Method clause defines how Locational Based Marginal Prices (LBMPs) are determined at specific bus locations within an electricity grid. It typically outlines the methodology for calculating the price of electricity at each bus, taking into account factors such as system demand, generation costs, and transmission constraints. For example, the clause may specify that LBMPs are calculated using real-time market data and reflect the marginal cost of serving an additional unit of load at a particular bus. This clause ensures transparent and consistent pricing for market participants, helping to allocate costs accurately and incentivize efficient grid operation.

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:

The LBMP at bus i can be written as: 𝛾𝑖 = 𝜆𝑅 + 𝛾𝐿 + 𝛾𝐶 Where: 𝛾𝑖 = LBMP at bus i in $/MWh 𝜆𝑅 = the system marginal price at the Reference Bus 𝑖 𝛾𝐿 = Marginal Losses Component of the LBMP at bus i which is the marginal cost of losses at bus i relative to the Reference Bus 𝑖 𝛾𝐶 = Congestion Component of the LBMP at bus i which is the marginal cost of Congestion at bus i relative to the Reference Bus the equation: Where: 𝛾𝐿 = (𝐷𝐹𝑖 − 1)𝜆�� 𝑖 𝐷𝐹𝑖 = delivery factor for bus i to the system Reference Bus and: Where: 𝐷𝐹𝑖 = (1 − 𝜕𝐿 ) 𝜕𝑃𝑖 𝑃𝑖 = injection at bus i The Congestion Component of the LBMP at bus i is calculated using the equation: 𝑖 𝛾𝑐 = − (∑ 𝐺𝐹𝑖𝑘𝜇𝑘) Where: 𝑘∈▇ 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 𝜇𝑘 = the Shadow Price of Constraint k expressed in $/MWh, provided however, this Shadow Price shall not exceed the Transmission Shortage Cost. Substituting the equations for 𝛾𝐿 and 𝛾𝐶 into the first equation yields: 𝛾�� = 𝜆�� + (𝐷𝐹𝑖 − 1)𝜆𝑅 − ∑ 𝐺𝐹𝑖𝑘𝜇𝑘 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.

  • Balance Computation Method For all accounts, dividends are calculated by the daily balance method, which applies a daily periodic rate to the balance in the account each day. Dividends will begin to accrue on the business day you deposit non-cash items (e.g., checks) to your account if deposited before the close of business. If you close any of your dividend earning accounts before dividends are credited you may not receive the accrued dividends up to the date of account closure.

Upon progress toward the completion of the Scope, as described in Section A of this Grant Contract, the Grantee shall submit invoices prior to any reimbursement of allowable costs.

  • Measurement method An isolation resistance test instrument is connected between the live parts and the electrical chassis. The isolation resistance is subsequently measured by applying a DC voltage at least half of the working voltage of the high voltage bus. If the system has several voltage ranges (e.g. because of boost converter) in conductively connected circuit and some of the components cannot withstand the working voltage of the entire circuit, the isolation resistance between those components and the electrical chassis can be measured separately by applying at least half of their own working voltage with those components disconnected.
