In the active distribution networks (ADNs), emerging trend of high penetration sustainable energy sources such as wind turbines, photovoltaics, and forthcoming integration storage devices additional dynamic loads like plug-in-electric vehicles (PEVs) influences to change nature electric networks. Consequently, it deteriorates power quality reliability in terms unacceptable voltage rise-drop, ha...

ABSTRACT: In any PV based system, the inverter is a critical component responsible for the control of electricity flow between the dc source, and loads or grid. This paper presents a solar PV generation system integrated to the grid. The results of matlab modeling of the system detail the comparative operation of inverter topologies which are the conventional two level inverters and multilevel ...

This article presents a novel technique to distinguish between magnetizing inrush current and internal fault current of power transformer. An algorithm has been developed around the theme of the conventional differential protection method in which parallel combination of Probabilistic Neural Network (PNN) and Power Differential Protection (PDP) methods have been used. Both PNN and PDP method ar...

In recent years, active filters have been considered and developed for elimation of harmonics in power networks. Comparing with passive, they are smaller and have better compensating characteristics and resistance to line distortions. In this paper, a novel idea based on adaptive filter theory in presented to develop an active filter to eliminate the distortions of an arbitrary signal. Using th...

This paper discusses the characteristics of powerfactor-correction (PFC) switching regulators of non-cascading structures in terms of efficiency, input current harmonic distortion, and load transient response. The discussion begins with simplified power flow diagrams of the non-cascading PFC switching regulators and describes their essential features for achieving power factor correction and ti...

At present, the research on five-level inverters mainly involves the modulation algorithm and topology, and few articles study the five-level inverter from the control strategy. In this paper, the nonlinear passivity-based control (PBC) method is proposed for single-phase uninterruptible power supply inverters. The proposed PBC method is based on an energy shaping and damping injection idea, wh...
