“…Another approach is to add passive filters that inject low impedance into the power system to absorb harmonic frequencies, but the disadvantage of this approach is that a passive filter utilizes more energy and takes a large amount of space. An active front end converter is utilized in this study and it is an effective approach that minimizes the total harmonic distortion, flexible regulation of dc-link voltage, provides unity power factor, and relatively sinusoidal input currents [57]. The block diagram of the active front with the control mechanism is illustrated in Figure 12.…”

In recent times, concerns over fossil fuel consumption and severe environmental pollution have grabbed attention in marine vessels. The fast development in solar technology and the significant reduction in cost over the past decade have allowed the integration of solar technology in marine vessels. However, the highly intermittent nature of photovoltaic (PV) modules might cause instability in shipboard microgrids. Moreover, the penetration is much more in the case of utilizing PV panels on ships due to the continuous movement. This paper, therefore, presents a frequency sharing approach to smooth the effect of the highly intermittent nature of PV panels integrated with the shipboard microgrids. A hybrid system based on an ultra-capacitor and a lithium-ion battery is developed such that high power and short term fluctuations are catered by an ultra-capacitor, whereas long duration and high energy density fluctuations are catered by the lithium-ion battery. Further, in order to cater for the fluctuations caused by weather or variation in sea states, a battery energy storage system (BESS) is utilized in parallel to the dc-link capacitor using a buck-boost converter. Hence, to verify the dynamic behavior of the proposed approach, the model is designed in MATLAB/SIMULINK. The simulation results illustrate that the proposed model helps to smooth the fluctuations and to stabilize the DC bus voltage.

“…Active front-end (AFE) plays an important role in several industrial applications presenting advantages such as bi-directional power, reliable dc-link voltage regulation, unity power factor, and sinusoidal line currents [1,2]. During the past decades, the three-level neutral-point-clamped (NPC) converter has been extensively used in medium voltage AFE applications.…”

Acting as an interface between the grid and many energy systems, the active front-end (AFE) has been widely used in a large variety of industrial applications. In this paper, in order to ensure the fast dynamic performance and good disturbance rejection ability of the AFE, a high-gain observer (HGO) plus adaptive super-twisting algorithm (STA) for the three-level neutral-point-clamped (NPC) converter is proposed. Comparing with the conventional PI control strategy, the proposed controller implements the adaptive STA in the voltage regulator to provide a faster transient response. The gains of the adaptive STA keep varying according to the rules being reduced in steady state but increasing in transient conditions. Therefore, the chattering phenomenon is mitigated and the dynamic response is guaranteed. Additionally, to undermine the impact of external disturbances on the dc-link voltage, a high-efficiency HGO is designed in the voltage regulation loop to reject it. Experimental results based on a three-level NPC prototype are given and compared with the conventional PI method to validate the fast dynamic performance and high disturbance rejection ability of the proposed approach.

“…Apart from FCS-MPC, deadbeat control (DBC) is another form of model based predictive control. This method has been widely used in the current control [13], [14], torque control [15], [16] and power control [17], [18] for motor drives and converters. In [10], a space vector modulation (SVM) based deadbeat predictive power control (DPPC) is investigated.…”

This paper presents a robust deadbeat predictive power control (DPPC) for PWM rectifiers with consideration of parameter mismatches under unbalanced grid conditions. Firstly, conventional DPPC is modified to extend its application to both ideal and unbalanced grid conditions. Secondly, tracking error of the modified DPPC with inaccurate grid-side impedance is analyzed. Thirdly, a discrete-time power disturbance observer (DPDO) is designed to achieve accurate power control with mismatched parameters. The designed DPDO can predict complex power at the next sampling instant and estimate system disturbance simultaneously. Therefore, the DPDO can contribute to eliminate steady-state tracking error resulting from disturbances caused by inaccurate parameters and compensate onestep delay in digital implementation. Although satisfactory steady-state performance can be obtained with modified DPPC and DPDO, transient performance still deteriorates significantly with inaccurate value of grid-side inductance. Thus, an online adaptive method to estimate mismatched inductance is finally developed based on the proposed DPDO. Both DPPC and DPDO are implemented in the stationary reference frame without coordinate transformation. Theoretical analysis confirms that the proposed DPDO can track disturbance without phase lag or magnitude error. Experimental tests and comparative studies with a prior DPPC on a two-level PWM rectifier validate the effectiveness of the proposed scheme.
