DIgSILENT model of a solar plant
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).
