A New SVM Method for Improvement of Power Quality in Multilevel Inverter

Some technology with several standards has been developed to address the problems like voltage dip, sag, and swelled. These advanced techniques mitigate undesirable quality issues. Precise monitoring is done by utilising proper power electronic devices.

So much research work is going on to give more focus to the microgrid network It has been studied from the literature that harmonic distortion and voltage stabilisation are the major cause of power quality issues which may result because of the evolution of nonlinear devices.

The power quality issues can be resolved by using different types of controllers like SVC, STATCOM, and filters. As the power is generated and power consumed or controlled through a power electronic interface, the storage system takes a vital role in its operation. It will continuously supply all types of loads for all types of situations. Inverters are implemented for power transfer from the DC source (Photo Voltaic) to the AC bus. This introduces harmonic to the system. Therefore, it is very essential to analyse the control strategy of PV-based inverters. This presents the SVPWM technique as the best possible technique for harmonic analysis. Several existing power quality improvement techniques and their merits and demerits have highly been present where each technique has a specific area of application. Only the pulse width modulation (PWM) technique has a broad area of usage, which include space vector modulation (SVM). advanced algorithm of PWM (Dodecagonal SVM) so on to mitigate the higher and lower order harmonics. They are technically pretty simple, possess high sensitivity, are inherently selective, immune to filter harmonic and external faults inherently selective, immune to filter harmonic and external faults. This presents the SVM technique as the best possible technique for the mitigation of harmonics, which formed one of the stimuli for the present research work.
