Department of Electrical Engineering and Computer Science. Louisiana

State University. Baton Rouge, USA.

Abstract

The article shows that the term “Power Quality” (PQ) seems to be only engineering jargon, therefore, it is suggested that the terms “Supply Quality” (SQ) and “Loading Quality" (LQ) are used in studies on Power Quality in electrical systems. Studies on PQ are associated with studies on Power Theory (PT) and compensation in systems with nonsinusoidal voltages and currents...READ MORE

Abstract

Micro-inverters are one of the many solutions to inject PV energy into the grid. They are usually composed of two stages: a first DC-DC stage that allows performing the MPPT (Maximum Power Point Tracking) function, adding galvanic isolation and raising the voltage to ease the operation of a second stage, the solar Grid Tie Inverter. An interesting and attractive proposal for this first stage is the Flyback converter due to simplicity, isolation, and few components, among others...READ MORE

Abstract

One of the biggest obstacles when it comes to the electrification of the vehicle fleet is the charging time of an electric vehicle (EV), which means that users of these vehicles, when they need to charge their car, always look for fast charging stations. This is the charging method that has the shortest duration. In the coming years, an increase in the proliferation of electric vehicles will lead to a greater demand for electricity, which in turn will put the distribution network to the test. Since the number of non-linear loads increases day by day, putting the distribution network under increasing stress, it is wise to study the effects of the high penetration of electric vehicles (EV) on the power quality of the network...READ MORE
