PTDF definition

PTDF means a measure of the responsiveness or change in electrical loadings on Transmission Facilities due to a change in electric power transfer from one area to another, expressed in percent (up to 100%) of the change in power transfer in the pre-contingency configuration of a system under study.

PTDF or ‘𝑃𝑇𝐷𝐹’ means a power transfer distribution factor;

PTDF means: Power Transfer Distribution Factor;

Examples of PTDF in a sentence

• For NYISO, the PTDF will equal the generator shift factor of the common scheduling point.

• For NYISO, the PTDF will equal the generator shift factor of the non-common scheduling point.

• Note that valid limits to the transfers tested would consist of those facilities for which a PTDF (power transfer distribution factor) or OTDF (outage transfer distribution factor) of 3% or greater exists.

• The Marginal Cost of Congestion at a PNode reflects a linear combination of the Shadow Prices of the binding Transmission Constraints (including Remedial Action Schemes) in the network, multiplied by the corresponding Power Transfer Distribution Factor (PTDF) and coefficient relevant to the transmission segment within that constraint, which is described in Appendix C.

• The Marginal Cost of Congestion at a PNode reflects a linear combination of the Shadow Prices of the binding Transmission Constraints in the network, multiplied by the corresponding Power Transfer Distribution Factor (PTDF).

• For NYISO, the PTDF will equal the generator shift factor of the non- common scheduling point.

• The determination of additional loading that can be incurred on a Flowgate begins first with the determination of the maximum loading that can be allowed on a PTDF Flowgate or on the monitored facility of an OTDF Flowgate during its associated contingency.

• Typically, new Flowgates should be either OTDF Flowgates with a TFC representing the total amount of power that can flow during a contingency without violating the emergency rating of the monitored facility or single facility PTDF Flowgates with a TFC equal to the normal rating of the single facility.

• The Marginal Cost of Congestion at a PNode reflects a linear combination of the Shadow Prices of all binding Constraints in the network, each multiplied by the corresponding Power Transfer Distribution Factor (PTDF).

• The table shall include all Flowgate data, which are applicable, including the Flowgate name, monitored facility, contingency facility, Flowgate rating, TRM, CBM, a and b multipliers, LODF, the TDF basis for the Flowgate (OTDF or PTDF), and the TDF cutoff threshold.

More Definitions of PTDF

PTDF or ‘’ means a power transfer distribution factor;

PTDF means Power Transfer Distribution Factor.

PTDF means a power transfer distribution factor which describes the impact of a bidding- zone net position or of a commercial exchange between two bidding-zones on a CNEC, as computed in the implemented CCM. In case the implemented CCM does not define how to compute PTDFs, these factors should be computed pursuant to Article 11 of the Core DA CCM.
