IDC PSS/E Base Case Clause Samples
The "IDC PSS/E Base Case" clause defines the standard reference model or dataset used for power system simulations and analyses within a contract or technical agreement. This clause typically specifies the version, parameters, and configuration of the PSS/E (Power System Simulator for Engineering) base case that all parties must use when conducting studies, such as load flow or contingency analysis. By establishing a common base case, the clause ensures consistency and comparability of results, thereby reducing disputes and misunderstandings about system conditions or study outcomes.

IDC PSS/E Base Case. GLDF
1. transmission facilities operated at 100kV and above, in the CA where the Flowgate’s monitored facility(ies) is located and in CAs that are first tier to the CA where the Flowgate’s monitored facility(ies) is located; or
2. transmission facilities operated at 100kV and above within 10 buses from the monitored facility(ies). If any Flowgates with a 3% to 5% distribution factor from Study 2 or Study 4 are impacted by 5% or more from a prior outage condition (Line Outage Distribution Factor (LODF) from this Study 3, the Flowgate will be added to the list of Coordinated Flowgates.
IDC PSS/E Base Case. In order to determine outage conditions (if any) that may cause the Operating Entity’s Control Zones/areas to have a significant impact on Flowgates, the Operating Entity will perform 2nd contingency (n-2) analysis, including both internal and external outages. This study will be performed offline utilizing MUST capabilities. If any additional Flowgates are found using this method, and they represent a 3% or greater impact when reexamined under Study 1 or 4, they will be added to the list of Coordinated Flowgates.
