Customer ServiceThis work is aimed at estimating internal PV panel parameters under outdoor conditions by using the impedance spectroscopy technique. The impedance is measured by leaving the PV panel in the real operative status corresponding to three operation zones: the open voltage circuit zone, the maximum power point zone and the short current zone. Since variations on the shunt
Customer ServiceThe developed dynamic model will be used to prepare a database containing an estimated frequency response of the PV impedance for both healthy and faulty cases. When compared with the picked up dynamic PV impedance response detailed in [ 25 ], it can decide the type and the degree of a detected fault.
The EIS technique is then proposed to estimate the most crucial internal parameters of the PV cell, namely series resistance, shunt resistance, and junction capacitance under low irradiance levels for the short-circuit zone, MPP zone, and open-circuit voltage zone.
Test 1: the two PV panels PV system are exposed to a constant irradiance value G = 940 Wm −2 and temperature T = 26, 9 °C (Fig. 14 a),
A solarimeter and an infrared thermometer were used to measure irradiance and PV cell temperature, respectively. Each PV panel is a set of 36 series PV cells of which every nine cells are related to a bypass diode.
In this context, a new dynamic two-diode model is proposed in this paper which makes it possible to overcome the drawbacks of the single-diode model on the one hand and to describe PV cell behavior on faulty cases on the other hand.
