Common use of Dynamic Simulation Data Clause in Contracts

Dynamic Simulation Data. NYISO provided a separate power flow base case for stability simulations and a set of stability setup files. In this power flow case, Athens was dispatched at 800 MW on three CT/GT sets. For consistency with the case used in steady-state analysis, Siemens PTI reduced the dispatch of the Athens plant from 800 MW to 700 MW on two CT/GT sets. The MW reduction was balanced by units in Ontario. This case is referred to as the Benchmark Case without SPS. Siemens PTI developed a stability power flow case with the SPS using the same approach as that in Section 2.1. In this case, Athens was increased to its full capacity i.e., 1080 MW, to increase flow on the Athens-Pleasant Valley and Leeds-Pleasant Valley (Lines 91 and 92) path. The additional Athens generation was dispatched against existing units in Con Ed. In both cases, flow on the UPNY-Con Ed interface was stressed to 11% higher than its transfer limit determined in the steady-state analysis. Details of the stressed cases are discussed in detail in Section 5. The dynamic model for stability simulation was obtained from the NYISO stability database and setup files.
