“…Control actions of the present state are considered in order to predict the control actions of the system in the next state. Like deadbeat control, it is also found sensitive to system parameter variations [136][137][138][139][140][141][142][143][144][145][146][147]. The topology for implementation of MPC on VSI is shown in Figure 33, whereas, its control schematic is depicted in Figure 34.…”

Abstract:In the modern era, distributed generation is considered as an alternative source for power generation. Especially, need of the time is to provide the three-phase loads with smooth sinusoidal voltages having fixed frequency and amplitude. A common solution is the integration of power electronics converters in the systems for connecting distributed generation systems to the stand-alone loads. Thus, the presence of suitable control techniques, in the power electronic converters, for robust stability, abrupt response, optimal tracking ability and error eradication are inevitable. A comprehensive review based on design, analysis, validation of the most suitable digital control techniques and the options available for the researchers for improving the power quality is presented in this paper with their pros and cons. Comparisons based on the cost, schemes, performance, modulation techniques and coordinates system are also presented. Finally, the paper describes the performance evaluation of the control schemes on a voltage source inverter (VSI) and proposes the different aspects to be considered for selecting a power electronics inverter topology, reference frames, filters, as well as control strategy.

“…Here, the synchronization is also performed by means of a PLL and a SOGI-based filter. The authors of [20] propose a robust predictive current controller using a disturbance estimator for the three-phase grid-connected VSC. The proposed method has rapid dynamic response due to the conventional predictive current controller, as well as low-cost implementation and robust control performance with regard to the disturbance and noise interference due to use of the combined estimation algorithm.…”

This paper proposes a grid voltage sensorless controller for single-phase voltage source converters. The controller is composed of an observer and a current control scheme. The proposed observer replaces the grid voltage measurement and is used to generate the current references and to compensate the perturbation effect of the actual grid voltage on the coupling inductor. This allows us to implement a simple proportional resonant current control algorithm. The proposed observer also estimates the grid frequency, allowing us to immunize the controller to grid frequency variations.

“…Hysteresis Current Control (HCC) and linear current control techniques are widely used in stationary reference frame control. [10] In three-phase grid connected inverters, the most commonly used modulation technique is Space Vector Pulse Width Modulation (SVPWM). This technique controls output voltage vector of inverter and provides optimum switching pattern.…”

The grid-connected issue is one of the major problems in the field of Power Electronics. In this paper, the Three Phase Voltage Source Inverter (VSI) is controlled by a Space Vector Pulse Width Modulation (SVPWM) Technique. SVPWM control technique and Park transformation, the managed inverter control system to convert input DC power into AC power, stabilize the output voltage and current, and feeds the excess power to the utility grid can be achieved by controllers. Usually, the grid source contains higher level of harmonics. To analyze the harmonics, nonlinear load is connected externally in the point of common coupling. The main aim of this paper is to modeling, simulation and experimental study of the three-phase grid connected inverter. By using the control algorithm, the grid sides Total Harmonics Distortion (THD) are controlled to the 1.54% for 800V DC as per the IEEE standard. The stimulation results such as AC output voltage and current, inverter system power flow, and grid disturbances detection signals, proves the effectiveness of the developed control algorithm. The control algorithms to makes the for this inverter outputs is pure sinusoidal.
