.PowerGrids.Electrical.Branches.BaseClasses.PiNetwork .PowerGrids.Electrical.Branches.BaseClasses.PiNetworkThis is the base class for branch components that can be represented as Pi-network with an ideal transformer with complex ratio at port_a. A diagram of the model is shown in the figure.
In general the impedances and transformer complex ratio are time-varying variables.
The model can be specialized to describe a transmission line with fixed or variable impedances, a transmission line with embedded circuit breakers, transformers with fixed or variable transformer ratio, transformers with tap changer/phase shifter, etc.
