In this paper, a novel approach is proposed for selective compensation of main voltage harmonics in a grid-connected microgrid. The aim of compensation is to provide a high voltage quality at the point of common coupling (PCC). PCC voltage quality is of great importance due to sensitive loads that may be connected. It is assumed that the voltage harmonics are originated from distortion in grid ...

Background: The theory of selective photo-thermolysis led to the development of a variety of different laser systems which range from the shorter spectrum of 694nm ruby laser to the middle with the 755nm alexandrite and 810nm diode lasers to the long end with the 1064nm (Nd:YAG) laser. Objective: A systematic review on the clinical trials with use of various laser sources for hair removal...

Multilevel inverters (MLI) are popular in high-power applications. MLIs generally configured to have switches reduced by switching techniques that eliminate low-order harmonics. The selective harmonic elimination (SHE) method, which significantly reduces the number of switching, determines optimal moments obtain desired output voltage and eliminates components. To solve SHE problem, classical m...

A two-step methodology was used to address and improve the power quality concerns for PV-integrated microgrid system. First, partial shading included deal with real-time issues. The Improved Jelly Fish Algorithm integrated Perturb Obserb (IJFA-PO) has been proposed track Global Maximum Power Point (GMPP). Second, main unit-powered via DC–AC converter is synchronised grid. To cope wide voltage v...
