DIgSILENT model of a solar plant

Information

A PV Plant implemented according to the DIgSILENT template in PowerFactory.

NOTE 1: The PLL Dynamics are missing along with the active power reduction models for FRT events.

NOTE 2: Keep in mind that if external irradiance is connected it needs to be matched for the initial active power for steady-state initialization.

Extends from OpenIPSL.Electrical.Essentials.pfComponent (Partial model containing all the parameters for entering power flow data).
