modelTwoGeneratorsConstantLoad
One generator with constant load at equilibrium
Extends from Models.PowerSystem.
Information
Test case with a two generator connected by a transmission line. Each generator has a local balanced load of 1 p.u. The model is at equilibrium, with zero power transfer along the line.
