Overview

The transmission model calculates the expected powerflow voltage results per node on a given feeder circuit.

Walkthrough

The transmission feeder model can be modified in real-time using a graphical interface by pressing the green 'Open Editor' button to the right of the name. Users are able to add, delete, relocate, or modify the information of each of the components. Once the feeder has been changed to your requirements, the simulation can be further customized using the following inputs:

  • Algorithm: The MATPOWER powerflow solver method. Can be set to NR (Newton Raphson), FDXB (Fast-Decoupled XB Version), FDBX (Fast-Decoupled BX Version) or GS (Gauss Seidel). These are the solution algorithms supported by MATPOWER.

  • Model: The powerflow formulation, set to AC or DC.

  • Tolerance: The termination tolerance for powerflow, in units P and Q dispatch per unit.

  • Iteration: The maximum number of iterations for the NR, FDXB, FDBX or GS solver methods.

  • Generation Limits: Whether or not to set power limits on the generators in the system. User can choose from “do not enforce” (0 code on backend), “enforce with simultaneous bus type conversion” (1 code on backend), and “enforce with one-at-a-time bus type conversion” (2 code on backend).
