“…The structure of a typical adaptive controller is shown in Figure 31. In the literature, some credible research articles and state-of-the-art techniques for adaptive controllers are found in [14,37,53,55,113,[122][123][124][125]. These controllers are applicable for both dynamic as well as static processes.…”

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.

A high-power reversible converter can achieve a variety of functions, such as recovering regenerative braking energy, expanding traction power capacity, and improving an alternating current (AC) grid power factor. A new hybrid traction power supply scheme, which consists of a high-power reversible converter and two 12-pulse diode rectifiers, is proposed. A droop control method based on load current feed-forward is adopted to realize the load distribution between the reversible converter and the existing 12-pulse diode rectifiers. The direct current (DC) short-circuit characteristics of the reversible converter is studied, then the relationship between the peak fault current and the circuit parameters is obtained from theoretical calculations and validated by computer simulation. The first two sets of 2 MW reversible converters have been successfully applied in Beijing Metro Line 10, the proposed hybrid application scheme and coordinated control strategy are verified, and 11.15% of average energy-savings is reached.

“…However, the transient time has not been taken into consideration during sudden change in load conditions. For improving the dynamic response in the dc-link voltage, an adaptive droop controller can be employed in the voltage controlled loop with optimal design of LCL filter on the grid side [9]. Still for simplicity of the decoupled grid power control, estimation of grid parameters is possible by feedback linearizing [10].…”

In this paper grid-voltage oriented control of gridside converter for wind power system is presented, which aims to optimize the performance of utility grid during transient conditions. To realize this objective, a digitally controlled inverter system is implemented which provides independent control of active and reactive power delivered to the grid under sudden change in reactive load. Initially, the proposed grid-voltage oriented control scheme is analyzed in order to manage the power flows into the grid followed by the mathematical modelling of grid-side converter. And then, a closed-loop control structure of the grid-side converter is implemented using a conventional proportional integral (PI) controller with space vector pulse width modulation (SVPWM) current controller. In order to analyze the results of the proposed study, in this paper, the complete system is modelled and simulated in the MAT-LAB/Simulink environment and the numerical results are discussed. The experimental results, obtained using DSP TMS320F2812 processor, confirm the high performance of the proposed control system in terms of good sinusoidal grid current, low harmonic content and fast dynamic response.
