“…Significant nonlinear loads such as electronic ballast, switch‐mode power supplies (SMPS), florescent lamps and compact fluorescent lamps (CFLs) are utilized in household applications, and they draw the distorted current from the utility grid. The proportional‐integral (PI) control [9], proportional‐resonant (PR) control [10] and hysteresis control [11], are commonly used for tackling the control over harmonics due to efficient nonlinear load. The PR control is a representation of the PI control in the rotating reference frame, and it is selected because it is able to control sinusoidal references unlike the PI control, which is able to control only constant set points.…”

This paper presents a sparse quaternion-valued minimization (SQVM) based control technique of a two-stage grid supportive photovoltaic (PV) power system with power conditioning capabilities. The grid side converter (GSC) is controlled by utilizing an SQVM control technique. The proposed algorithm enables the GSC to mitigate the load harmonics current and provides reactive power compensation at the point of common coupling (PCC). The proposed control is tuned to mitigate the DC offset error, harmonics current and to improve the frequency response of the proposed system. A DC link pre-predictive is incorporated to improve the dynamic response by reducing the burden on the outer Proportional-Integral (PI) voltage controller loop. Further, it is used to extract the fundamental component of load currents for generating the reference currents. An adjustable DC link voltage loop is incorporated in the proposed control technique to adapt the PCC voltage variation, which helps in minimizing the losses of the PV system. For real-time execution of the adjustable DC link voltage concept, the DC link voltage is adapted with a variation in the PCC voltage. The operation and control of the system topology are validated experimentally under various scenarios.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…The output of the converter is controlled by pulse width modulation (PWM) technique, 18 selection of which strongly decides the quality of line current ripple, switching energy loss of the converter, pulsating torque in the machine, utilization of the DC base voltage, and generator acoustic noise level. [19][20][21] So incorporation of the efficient PWM technique in WECS (wind energy conversation system) becomes very integral. Since PWM is one of the most popularly used PWM technique compared to SPWM other continuous PWM techniques like third harmonic injection (THI-PWM) and conventional space vector PWM(CSVPWM) have higher line voltage utilization capability.…”

This work presents a novel speed sensor less air-gap flux-oriented vector control of dual stator induction generator (DSIG) used for grid connected, variable speed wind energy generation system. The DSIG consists of two stator windings electrically separated by an angle of 30 with dissimilar pole numbers, which are in the ratio of 1:3. This arrangement offers reduced magnetic core saturation and less harmonics in stator currents, which results into reduced stator winding losses. Moreover, presence of two stator windings makes DSIG suitable to be used in high power application. In conventional rotor-fluxoriented control, the rotor flux is oriented along the d-axis of the rotor winding. But the rotor flux is not easily accessible. Air-gap flux-oriented vector control (AGFOVC) is advantageous as compared to conventional vector control because the air-gap flux is easily accessible and does not require any special arrangement for the measurement of variables. Moreover incorporation of this novel speed sensor less air-gap flux-oriented vector control also eliminates the use of speed encoder as the rotor speed is estimated from the machine terminal variables.Elimination of speed encoder not only reduces the cost of the overall system but also nullifies the error due to mismeasurement of speed and enhances control flexibility and robustness. As a result of which robustness of the system increases. Here, two separate converters are used for the two stator windings of the machine. And the converter switching's are being performed by space vector-based novel dwell time optimized 13-zone hybrid PWM.

In this study, an efficient system is designed to maintain the Direct Current (DC) link voltage and improving voltage gain at remote side inverter using Hysteresis Controller (HC). The energy from wind is fed to the Remote Area Power Systems (RAPS). There is a need to control the changing frequency due to environmental changes in order to sustain the voltage at inverter side. It is achieved by the HC controller that provides control signals to inverter switches. The two-levels of Energy Storage System (ESS) are used as battery at source side and transformer at load side. The battery stores energy from the power converter stage through bi-directional converter where the energy flows in both forward and reverse direction. The frequency regulation based RAPS system is implemented using MATLAB/Simulink tool.
