Load Flow Equivalent


Description

The load flow equivalent helps where components that are not supported by the load flow algorithm are used. For example, when importing a model from Simulink or developing a network type UCM that can have an impact on the power flow solution, the user can add a load flow equivalent next to it to input the values to be considered by the load flow algorithm to determine the steady-state solution of the network.
