what is the meaning of ptdf

Although the Petroleum Technology Development Fund (PTDF) was established, originally to, among other things, accelerate the development of indigenous manpower for Nigeria's vital oil and gas industry, it can, nevertheless, carve out a role for itself in the funding of Nigerian Academic Libraries. The Petroleum Technology Development Fund (PTDF) was established by Act No. 25 of which repealed the Gulf Oil Company Training Fund Act. Prior to the establishment of PTDF, there existed the Gulf Oil Company Training Fund, the assets of which were transferred to the Fund upon promulgation of the Act setting it up.

Power Transfer Distribution Factors PTDF indicate the incremental change in real power that occurs on transmission lines due to real power transfers between two regions. These regions can be defined by areas, zones, super areas, single buses, injection groups or the system slack.

These values provide a linearized approximation of how the flow on the transmission lines and interfaces change in response to a transaction between the Seller source and the Buyer sink. These values can then be visualized on the onelines using animated flows see below for details. When considering areas, zones, or super areas as part of the transaction, the transaction for which the PTDFs are calculated is modeled by effectively scaling the output of all generators on AGC in the source and sink areas in proportion to their relative participation factors.

Generators in the source area effectively increase their output, while generators in the sink area effectively decrease their output. When including injection groups as part of the transaction, the AGC status of any participating generators does not matter. All generators in the injection group with non-zero participation factors will be included in the transaction.

When loads are included in injection groups, loads in the Seller would be effectively decreased in order to effect a transaction and loads in the Buyer would be effectively increased in order to effect a transaction. Buses in the injection group are also allowed to participate in the transaction even if the bus has no generation or load. Buses are modeled as an increase in injection if in the seller and a decrease in injection if in the buyer.

Of course, the PTDF calculation is a linear calculation and no changes are actually made to the output of generators, loads, or buses to study the impact of the transaction regardless of the type of seller or buyer.

An important aspect to consider in calculating the PTDF is how the losses associated with the transfer are allocated. In other words, the Buyer accounts for the entire change in the system losses. The animated flows that appear on the oneline diagram may represent either actual flows or PTDF values. Once this button is clicked, the flow arrows on all open onelines will represent distribution factors, any transmission line pie charts will show PTDF values, and the caption of the button will change to Visualize Actual Power Flows.

Click the button again to visualize actual power flows instead of distribution factors. The distribution factors are calculated and displayed for the element set of your choice in the table at the bottom of the dialog.
