Class BusStateMap

java.lang.Object

com.powerdata.openpa.se.BusStateMap

public class BusStateMap
extends java.lang.Object

Relate SE state variable (offsets in state vectors or columns in measurement jacobian) to buses using current topology. The state variables are voltage magnitudes and angles for all non-reference buses.
