*2.1. The Hybrid Plant*

A PV plant rated 100 MVA with four PV arrays of 25 MVA each was constructed in Simulink. Each 25 MVA array was assumed to have a lumped DC/DC converter and a lumped DC/AC inverter. A 100 MVA TPSH dynamic model was constructed in Simulink. The TPSH and PV plant were coupled together to the grid using a 110 MVA step-up transformer, as shown in Figure 2.
