“…The control circuit of the SHAPF produces the reference current, which is compared with the output inverter current. When the output inverter current increases out of the designed limits of the hysteresis band controller, the hysteresis band controller switches will be turned off and on [53].…”

Power quality improvement faces different and significant problems due to voltage instability and the wide use of electronic power devices. To overcome these different power quality problems, an active power filter is used. The active power filter, in general, has 4 main categories- shunt, series, unified power quality conditioner, and hybrid active power filter. The shunt active power filter is usually used to mitigate source current harmonics and compensate reactive power for power factor correction. The series active power filter is usually used to mitigate voltage problems (sags, swells, transients, dips, distortions, harmonics, etc.). The unified power quality conditioner is a combination of the shunt active power filter and the series active power filter; it is used to mitigate all voltage and current problems, compensate voltage, current system harmonics, and reactive power compensation, and mitigate voltage dips, voltage sags, voltage swells, and voltage phase shift. In this paper, the 3-phase 3-wire unified power quality conditioner is utilized to mitigate all power system problems (voltages and currents) and discuss the effect of the shunt and series active power filter separately on source voltage and source current waveforms. This case study shows that the source voltage distortion can be mitigated by using the series active power filter alone, but the source current distortion cannot be mitigated without using both the series and shunt active power filter. The source current harmonic problem mainly exists due to 1) distorted voltage sources, and 2) non-linear loads. Therefore, the unified power quality conditioner must be used to mitigate source current distortions in the case of the distorted voltage source, to comply with the standard limits IEEE 519, IEC 555, and IEC 61000. HIGHLIGHTS The UPQC is used to mitigate all voltage and current problems and improve all power system quality The SEAPF eliminates all voltage problems The SHAPF has no effect on source voltage The SHAPF eliminates source current harmonic distortion GRAPHICAL ABSTRACT

“…One of the disadvantages of hysteresis controller is that it has high switching frequency which leads to undesirable harmonics. A modified hysteresis controller is presented to reduce switching losses in grid-connected inverter system [17][18][19]. The proposed hysteresis controller is proven to have the ability to minimise switching losses without sacrificing output current waveform.…”

The use of renewable energy sources is highly demand in electricity market nowadays. The incorporation of renewable energy sources with the utility grid has becoming a challenging task in power system as it arises several control issues such as grid stability, power quality control, loads sharing and others. This paper presents current control methods namely Hysteresis controller and Proportional-Integral controller used to interface of single-phase grid connected inverter with nonlinear load. The impact of nonlinear load on grid current is analysed by measuring the performance of total current harmonics distortion (THDi) level in MATLAB TM Simulink software environment.

“…There are numerous inverter control strategy have been discussed for optimal control of modulation index and firing angle of the inverter. However, the conventional algorithms such as predictive controller, hysteresis controller, sinusoidal pulse width modulation (SPWM) of inverter control are difficult and complex for required tuning process [23][24][25]. Compared to classical current control methods, the space vector pulse width modulation (SVPWM) is the predominant method as it is based on linear control and has advantage of fixed switching pattern, low switching losses, utilisation of dc-link voltage and less current harmonic content over other voltage source inverter (VSI) current control methods [26].…”

This research study presents the fuzzy space vector pulse width modulation (FSVPWM) method of current control for three-phase voltage source inverter. The hybrid fuzzy particle swarm optimisation-based maximum power point (MPP) tracking algorithm has been employed to obtain high tracking efficiency as well as optimal MPP under adverse operating states. The FSVPWM technique provides less current harmonic content, fixed switching pattern, protection from over current, low switching losses and able to handle the non-linearities and uncertainties of the photovoltaic-wind grid integrated system. Grid synchronisation with sinusoidal current injection is achieved using the inverter controller. Fuzzy logic controller-based SVPWM controller compensates current error and provides DC-link utilisation with high efficiency. The experimental responses have been validated using MATLAB/Simulink interfaced real-time dSPACE DS 1104 controller. Irrespective of solar irradiance and wind velocity, the proposed hybrid system obeys MPP accurately with high performance.
