Transmission Reliability Margin (TRM) definition

Transmission Reliability Margin (TRM) means the amount of margin kept in the total transfer capability necessary to ensure that the interconnected transmission network is secure under a reasonable range of uncertainties in system conditions.
Transmission Reliability Margin (TRM) means the amount of margin earmarked in the total transfer capability to ensure that the interconnected transmission network is secure under a reasonable range of uncertainties in system conditions. [Grid Code 2023, Regulation 3(1) (130)]
Transmission Reliability Margin (TRM) means the amount of margin kept in the total transfer capability necessary to ensure that the interconnected transmission network is secure under a reasonable range of uncertainties in system conditions Available Transfer Capability (ATC)” means the transfer capability of the inter –control “ area transmission system available for scheduling commercial transactions (through long term access, medium term open access and short term open access) in a specific direction, taking into account the network security. Mathematically ATC is the Total Transfer Capability less Transmission Reliability Margin The STU shall asses the Total Transfer Capability (TTC), Available Transfer Capability (ATC) and Transmission Reliability Margin (TRM) of inter-State links / Corridors. TTC, ATC, and TRM along with the details of basis of calculations, including assumptions if any, shall be put up on the website of STU.

Examples of Transmission Reliability Margin (TRM) in a sentence

  • The Transmission Reliability Margin (TRM) will be established at a level which incorporates the uncertainties and continued variability of system conditions and the practical limitations of system control.
