“…With the quick increase in solar irradiance, the PV generation may cause the voltage to exceed, which is overload [3], and other problems will arise when the PV system steps into an island model once the grid fails [4]. An intelligent PV inverter can transform the PV generation from a stability hazard to a stability asset using the controlling function [5][6]. For several decades, scientists [7][8][9][10] have studied and discussed updating the grid specifications related to the PV inverters to include the above capabilities, which some grid regulars have implemented.…”

Due to environmental and energy policies in recent years, some countries will install many PV generations into power systems in the future. Under this condition, it is worrisome that the disconnection of the PV occurs because of a voltage drop triggered via a system fault, which impacts the stability of the PV(photovoltaic).A technique of FRT (Fault Ride Through) is an expected solution for PVs. However, just the FRT requirements for PVs do not inevitably increase the stability of the power system. Solving the problem of the instability of the inverter control in a grid-connected PV needs reasonable consideration. This paper proposed an automatically independent controlling algorithm of the PV inverter considering dynamic load features and Active LVRT (low voltage ride through) capability to increase the robustness and performance of the grid-connected PV system, and both simulation and experimental results showed that the condition of a range from an IM rate = 20[%] to an IM rate=40[%] could best meet the requirements for the PV Outputting recovery and the average tracking error of the input current reduced by nearly 10%, also the average output current tracking error reduced by about 4%, which shows that the tracking performance has significantly improved.

Sharp LC resonance peak may enlarge inherent harmonics, dominant harmonics of the supply voltage generated by a three-phase diode rectifier, around the resonance frequency, which will intensify fluctuations of the DC-link voltage and grid currents in motor drives with small DC-link capacitor. In this paper, a novel resonance suppression strategy based on inherent harmonics impedance shaping is proposed specially for three-phase input PMSM drives with small DC-link capacitor. Instead of increasing the damping of the whole system for resonance suppression, the motor side power disturbance can be reduced by designing the impedance for inherent harmonics around LC resonance frequency, based on the new model with the consideration of motor side characteristic. For damping current generation, the angle of the virtual admittance is modified to eliminate the influence of the DC-link voltage sampling delay. Experimental results show the effectiveness of the method on a prototype of electrolytic capacitorless PMSM drive.
