Case 1: If the available PV energy added with the minimum
gas turbine energy is less than the demanded
load energy ( _ EPV _1/2h + _ EMGT_1/2h_min <
_ Eload_1/2h), the PV panels can work with a
maximum power point tracking (MPPT) algorithm,
and all PV power is injected in the grid. The gas
microturbine has to generate the missing power
