To seek the most remarkable power sources, MPPT control calculation is necessary [29].

Increased usage of combined PV-Wind renewable energy sources is seen as a positive step toward reducing air pollution and carbon emissions. However, since non-linear loads have increased dramatically, voltage quality and harmonic distortion concerns have arisen, affecting the operation of combined PV-Wind RES and smart-grid electrical transmission structures. This study shows how a Shunt active power filter may improve energy quality in a microgrid structure at the distribution level. The major goal of this article is to find an appropriate controller approach for improving the shunt active power filter's compensating capacity. This paper simulates a PV-Wind hybrid renewable energy system that operates in the presence of unpredictably variable solar and wind energy resources. The objective is to allow the construction of an electrical control structure that produces the right duty cycle. It will aid in the regulation and stabilization of voltages at dc/dc energy conversion plant. Simulation is used to assess the proposed control system's ability to enhance power quality. The device's compensating capability is mostly determined by the DC link capacitor voltage control. The closed loop functioning of a proportional integral controller is used to attain this voltage regulation in the past. To increase the functioning of a shunt active power filter, the MOPSO procedure approach has been presented. The performance of suggested approaches and the comparison of different pulse generating strategies have been validated in the SIMULINK/MATLAB model environment. The suggested technology successfully improves power quality on the grid and maintains a steady voltage on the grid despite variations in RE output and load.

As the scale of power systems is increasing day by day with distributed generation [6], [7] connected to a grid, high-level fault currents might be caused during a contingency. Recently, many devices such as split bus bars, transformers with higher impedance, and fuses have been used in industry to reduce the peak value of fault currents.…”

Short circuit current limitation in distribution system utilities can be an operational approach to improve power quality, since the estimated voltage sag amplitude during faults may be intensely reduced. The application of superconducting fault current limiter (SFCL) is projected here to limit the fault current that occurs in power system. SFCL utilizes superconductors to instantaneously decrease the unanticipated electrical surges that happen on utility distribution and power transmission networks. SFCL considerably decrease the economic burden on the utilities by reducing the wear on circuit breakers and protecting other expensive equipment. The designed SFCL model is used for determining an impedance level of SFCL according to the fault current limitation necessities of different types of the smart grid system. The representation of this paper about to see the optimum resistive value of SFCL for enhancing the transient stability of a power system. The assessment of optimal resistive value of the SFCL connected in series in a transmission line with a conductor throughout a short circuit fault is consistently determined by applying the equal-area criterion supported by power-angle curves. A Simulink based primary model is developed and additionally the simulation results for the projected model are achieved by using MATLAB.

This paper presented with problems related with voltage flicker in power system networks. Several international standard issued to control the voltage flicker are briefly described and some important methods to analyse electrical circuits with sinusoidal and non-sinusoidal waveforms are introduced and evaluated. One of these methods-Cockcroft Walton Voltage Multiplier (CWVM) has been used to increase the voltage of a filter, which is also described in this paper as a practical application. The filter can compensate for harmonic currents, power factor, and unbalance voltage.The simulation results using Multisimare presented, showing that good dynamic and steady-state response can be achieved with this approach. Keyword: CWVM INTRODUCTIONVoltage interruption and fluctuation are the most significant power quality disturbances for consumers due to their significant unfavourable impact on electronic equipment. The system voltage fluctuation mainly caused by the faults in the power system and sometimes by the energization of large Induction Motors. In the early 90s, the impact of voltage fluctuation was measured using magnitude and duration indices and compared with the power quality envelope. Therefore, fluctuation creates competition among utilities to provide their customers with reliable power quality (PQ). PQ means voltage quality (VQ) from the customers" perspective [1]. This perspective motivates PQ research towards the mitigation of VQ problems in order to improve PQ in distribution systems. Although much work has been done in the extraction and compensation of each common PQ disturbance, few compensation strategies for several VQ problems have been developed [2]. In fact, there is a tremendous need for such generalised compensation strategies because of high probability for finding several VQ problems existing at the same bus, the same feeder or at the same load [3][4][5][6][7][8][9]. On the other hand, a utility is likely to take sufficient measures that limit the interruptions due to voltage fluctuations. The utility should evaluate the voltage performance of the distribution system by performing studies that will provide it with information on the voltage magnitude, duration, and frequency at a node where a sensitive load is likely to be connected. If the sag performance is inadequate, the utility should take measures to improve that performance. An alternate approach to assess the voltage performance is by means of computer simulation. Two methods that are generally used are the method of fault positions and the method of critical distances [10]. The voltage sag performance of a hypothetical distribution system has been assessed in reference [11]. This study uses the Kalman filter, the
