CONCLUSION

Control techniques to direct voltage of an independent variable speed wind turbine with a PMSG, battery, power device, and electrolyzer (goes about as dump stack) are displayed in this paper. By keeping up dc interface voltage at its reference esteem and controlling adjustment records of the PWM inverter, the voltage of inverter yield is kept up consistent at their evaluated qualities. From the reproduction results, it is seen that the controller can keep up the heap voltage great regardless of varieties in wind speed and load.An calculation is created to accomplish clever vitality the executives among the breeze generator, battery, power device, and electrolyzer. The impact of uneven load on the generator is examined and the dc– dc converter control plot is proposed to diminish its impact on the electrical torque of the generator. The dc– dc converter controller not just aides in keeping up the dc voltage steady yet additionally goes about as a dc-side dynamic channel and diminishes the motions in the generator torque which happen because of unequal load. PWM inverter control is consolidated to make the line voltage at PCC adjusted under an uneven load situation. Inverter control additionally helps in decreasing PCC voltage journey emerging because of moderate elements of water elctrolyzer when control goes to it. The complete consonant mutilation (THD) in voltages at PCC is about 5% which portrays the great nature of voltage produced at the client end. The recreation results exhibit that the execution of the controllers is agreeable under unfaltering state just as unique conditions and under adjusted just as lopsided load conditions.

Thermal Stresses Relief Carrier-Based PWM Strategy for Single Phase Multilevel Inverters

ABSTRACT

Enhancing power cycling capability of power semiconductor devices is highly demanded in order to increase the long term reliability of multilevel inverters. Ageing of power switches and their cooling systems leads to their accelerated damage due to excess power losses and junction temperatures. Therefore, thermal stresses relief (TSR) is the most effective solution for lifetime extension of power semiconductor devices. This paper presents a new thermal stresses relief carrier-based pulse width modulation (TSRPWM) strategy for extending the lifetime of semiconductor switches in single-phase multilevel inverters. The proposed strategy benefits the inherent redundancy among switching states in multilevel inverters to optimally relieve the thermally stressed device. The proposed algorithm maintains the inverter operation without increased stresses on healthy switches and without reduction of the output power ratings. In addition, the proposed algorithm preserves voltage balance of the DC-link capacitors. The proposed strategy is validated on single phase five level T-type inverter system with considering different locations of thermal stresses detection. Experimental prototype of the selected case study is built to verify the results. Moreover, comparisons with the most featured strategies in literature are given in detail.

This paper presents the main parts of the invert er and The proposed invert er with the simple control easily obtains any voltage reference. Therefore, the invert er acts as a harmonic source when the reference is a non-sinusoidal signal.

prototype

The validity of the proposed invert er based SAP F is verified by simulation as well as experimental study. Both simulation and experimental results show that the proposed multilevel invert er is suitable for SAP F applications.

Single-Phase Inverter with Energy Buffer and DC-DC Conversion Circuits

ABSTRACT:

This paper proposes a new single-phase invert er topology and describes the control method for the proposed invert er. The invert er consists of an energy buffer circuit, a dc-dc conversion circuit and an H-bridge circuit. The energy buffer circuit and H-bridge circuit enable the proposed invert er to output a multilevel voltage according to the proposed pulse width modulation (P WM) technique. The dc-dc conversion circuit can charge the buffer capacitor continuously because the dc-dc conversion control cooperates with the P WM. Simulation results confirm that the proposed invert er can reduce the voltage harmonics in the output and the dc-dc conversion current in comparison to a conventional invert er consisting of a dc-dc conversion circuit and H-bridge circuit.

Simulation demonstrates that the proposed invert er can output currents of low total harmonic distortion and have higher efficiency than the conventional invert er. In addition, these features of the proposed invert er contribute to the suppression of the circuit volume in spite of the increase in the number of devices in the circuit.

Grid Connected Wind- Photovoltaic hybrid System

ABSTRACT

 This paper presents a modeling and control strategies of a grid connected Wind-Photo voltaic hybrid system. This proposed system consists of two renewable energy sources in order to increase the system efficiency. The Maximum Power Point Tracking (MP PT) algorithm is applied to the P V system and the wind system to obtain the maximum power for any given external weather conditions. The Field Oriented Control (F O C) controls the generator side converter, moreover this approach is used to control independently the flux and the torque by applying the d- and q-components of the current motor. The Voltage Oriented Control (V O C) strategy controls the utility grid side converter which is adopted to adjust the DC-link at the desired voltage. The simulation results using mat lab software environment prove the good performance of these used techniques so as to generate sinusoidal current wave forms. This current synchronizes with the grid voltage, Moreover, the DC bus voltage is perfectly constant because only the active power is injected into the grid. Simulations are carried out to validate the effectiveness of the proposed system methods.

Single Phase Dynamic Voltage Restorer Topology Based on Five-level Ground point Shifting Inverter

ABSTRACT

A Single Phase Dynamic Voltage Restorer (DVR) based on five-level ground point shifting multilevel inverter topology has been proposed in this paper. The proposed inverter has a floating ground point. Therefore, by shifting the ground point, it is observed that the inverter circuit gives five output voltage levels from single DC voltage source. This configuration uses less number of switches compared to the existing multilevel inverter topologies. A fast sag swell identification technique using d-q reference frame is also discussed in this paper. This proposed topology of the DVR can compensate voltage sag, swell, flicker and maintain the required voltage at the load bus. The detailed simulation study is carried out using MATLAB/Simulink to validate the result.
