.PowerGrids.Electrical.Buses.ReferenceBus

Information

When an isolated synchronous grid is initialized in steady state, the reference angle remains undefined. In order to make the angles well defined, this ReferenceBus component should be used in the position where the power flow problem has the slack node.

The purpose of this component when the grid is initialized in steady state is twofold:

If setPhaseOnly is set to true, then only the initial phase of the bus voltage is set to the same value of the power flow, i.e., UPhaseStart. The initial voltage magnitude is computed to ensure zero reactive power flow QSlack.
