Partial model for an unbalanced PV source

Buildings.Electrical.AC.ThreePhasesUnbalanced.Sources.BaseClasses.BaseUnbalancedPV

Information

This model is a partial class extended by three-phase unbalanced PV power sources.

The model has boolean parameters plugPhase1, plugPhase2, and plugPhase3 that can be used to connect the PV in an unbalanced configuration.

The model has an array areaFraction[3] that is used to determine how to partition the power of the PVs on the three-phase. By default it is assumed a uniform partition areaFraction[3] = {1/3, 1/3, 1/3}.

Extends from Buildings.Electrical.Interfaces.PartialPluggableUnbalanced (Partial interface for unbalanced loads), Buildings.Electrical.Interfaces.PartialPvBase (Partial model with basic parameters for PVs), Buildings.Electrical.Interfaces.PartialAcDcParameters (Partial model that contains basic parameters for a DC/AC conversion system).
