This paper provides a comprehensive review of the control approaches and the powerdecoupling topologies to mitigate 2ω-ripple problem in the single-phase inverters, its solutions, and discusses open challenges yet to be addressed. The cause and effects of 2ω-ripple problem and its solution based on the passive and active power-decoupling techniques are discussed. A subcategory of the active power-decoupling technique nominated as the control-oriented compensation technique is reviewed in detail, this technique can achieve the ripple-mitigation at the source through the control but not necessarily adds extra circuit or active filter to the system. The control-oriented compensation techniques can be applied in the two-stage DC-DC-AC converters and the single-stage inverters having a front-end control capability with the H-bridge such as in the quasi-switched-boost inverters. The merits and associated challenges of these techniques are listed and summarized in a tabular form. Finally, a conclusive discussion with open challenges is presented. INDEX TERMS 2ω−ripple, Single-phase Inverter, Control strategies, Power-decoupling schemes.

“…So, bulky aluminum electrolytic capacitors are used to limit large bus voltage transient fluctuation. In addition, active ripple cancellation circuits [9], [10] decoupled the pulsating power from the average power, which resulted in a lower bus capacitance and a higher loop bandwidth. However, these techniques require extra semiconductor switches, additional passive components, and additional control schemes.…”

Fast Bus Voltage Control of Single-Phase Grid-Connected Converter With Unified Harmonic Mitigation

et al. 2023

This paper presents a comprehensive analysis of the harmonic sources of the single-phase gridconnected voltage source converter (VSC), which leads to an alternative approach for DC bus voltage control of the VSC under grid voltage distortion with a significant switching dead time. A selective current harmonic controller with the zero-reference structure plays a vital role in rejecting the harmonic components in the grid reference current created by the bus voltage control loop and the harmonic components in the grid voltage and in the VSC caused by the switching dead time. Therefore, the bus voltage control can adopt a conventional proportional-integral regulator tuned at a fast bandwidth. The proposed control scheme implemented in the multiple unbalanced synchronous reference frames was validated with a bidirectional 2-kVA VSC under grid voltage distortion and a significant dead time. Furthermore, the proposed control scheme exhibited the transient response and grid current quality superior to the conventional bus voltage control methods with a notch filter and a low-pass filter. The proposed control scheme has inherent frequency adaption.INDEX TERMS Current distortion, dead time, double-frequency ripple, renewable energy.

“…So, to convert the maximum power of a PV system to the AC load, voltage must be adapted to it under changing solar irradiation. So, the connection of power electronic devices between the PV system and the battery in addition to the AC load plays an important role in achieving balance [5][6][7].…”

This paper presents an application of fractional control scheme named Tilt Integral Derivative (TID) to control a stand-alone hybrid energy system composed of a solar photovoltaic (PV) system and a battery bank (BB). A three-level NPC inverter is inserted in order to increase the efficiency of the energy injected into the AC load. Variation in solar radiation or AC load may cause power imbalance, which leads to variation in DC link voltage. As a solution, a buck-boost converter is connected between the DC link and the battery bank to ensures the transfer of energy in both directions. The parameters of TID controller were tuned using a powerful optimization technique known a Genetic Algorithm (GA) by minimizing the Mean Square Error (MSE) used as a performance index. The effectiveness of the proposed TID controller is demonstrated through a comparison with a conventional Proportional-Integral-Derivative (PID) controller, whose parameters are computed by the pidtool function of the Matlab/Simulink tool where the DC link voltage behavior is previously modeled by a capacitor transfer function. The obtained results show that the proposed TID controller provides a stable DC bus with low chattering, regardless of the rapid irradiation and load changes, when compared to a conventional PID controller.
