Abstract

Dual-Quadrature Signal Generator (D-QSG) based Phase lock loop (PLL) has been recently proposed to handle the nonideal grid voltage conditions. However, selecting the parameter for D-QSG based controller has been a great challenge, especially for higher-order systems. Inappropriate parameter selection tends to increase settling time both in terms of amplitude as well as harmonics attenuation. Hence, in the proposed work, the main focus is on parameter selection to achieve a faster response. Here, a fourth-order Quasi-Synchronous Generator has been realized by cascading the two nonidentical second order generalized integrators (NISOGIs). Furthermore, the parameters of both the NISOGIs are selected in such a way that gives a faster envelope around the 2\% settling time threshold in 24.4 ms. This method provides a more condensed distance within a Fourth-Order transfer function's poles, which eventually results in a faster reaction time. A suggested method has been used to regulate an EV charger during harmonics and voltage sag/swell instead of interfering with regular operation. Furthermore, the EV charger can readily adjust the level of active and reactive power in accordance with the established benchmarks while compensating for load harmonics. Both MATLAB/Simulink and Real-time platform provided by OPAL-rt prove the effectiveness of this approach.
