Prоblem 4: (а) (15 pоints): The pаrаmeters оf a PV panel with 60 cells in series at 1000 W/m2 irradiance and 25oC are given below. Isc = 10 A, Voc = 35 V and slope dI/dV at Isc is -0.003 A/V.  Derive a suitable model for this PV panel under the given conditions (neglect series resistance and assume a = 1). If the panel is loaded at STC such that the terminal voltage is 32 V, calculate the power delivered by the PV panel to the load. (b) (10 points): In a three-phase system the d and q axis voltages and currents respectively are as follows. vd = 500 V, vq = 0, id = 80 A, iq = 20.  Calculate the peak value of phase voltage, va , and calculate the active power and reactive power corresponding to this system.
