“…A semiconductor device converts a variable DC input voltage to the fixed DC output voltage by adjusting the duty cycle (D) under all conditions of solar irradiances. Figure 5 shows the circuit of DC‐DC buck‐boost converter and block diagram of the voltage controller 2 . The switches are controlled by pulse width modulation (PWM) technique, where the inputs to the converter are the PV generator voltage, V d , and a predefined set value, V set .…”

“…Numerous research articles have been published with the aim of studying the impact of the addition of a PV generator to the power system, such as the one with a high PV penetration to the SMIB, and the results have shown that the operating point of the device is stable 1 . In addition, a failure of an SMIB power system with high PV penetration and constant injection voltage is outlined 2 . The system is found to be robust and able to withstand a significant disturbance.…”
