increasing of word demand load caused a new distributed generation (dg) to enter to powersystem. one of the most renewable energy is the photovoltaic system. it is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.in this paper an optimal pid controller for photovoltaic system systems has been developed. theoptimization techni...

Abstract: In recent years, the increasing penetration level of wind energy into power systems has brought new issues and challenges. One of the main concerns is the issue of dynamic response capability during outer disturbance conditions, especially the fault-tolerance capability during asymmetrical faults. In order to improve the fault-tolerance and dynamic response capability under asymmetric...

Power electronics-based converters have been widely used in several applications, specifically electric propulsion systems. Ongoing advancements led to high-gain Quadratic Boost Converters (QBC) which control Permanent Magnet Synchronous Motor (PMSM) drive. In this work, a novel scheme is employed, particularly three-phase inverter between QBC and PMSM operated by dual-mode controller strategy....

This paper presents a combined control and modulation technique to enhance the power quality (PQ) reliability (PR) of hybrid energy system (HES) through single-phase 11-level cascaded H-bridge inverter (11-CHBI). The controller specifically regulate HES meet load demand. To track optimum power, Modified Perturb Observe (MP&O) is used for HES. Ultra-capacitor (UCAP) based storage device novel cu...

A novel platinum-mediated process involving intermolecular activation of a C(aryl)-H bond of toluene, intramolecular activation of an imine C(aryl)-Cl bond and formation of a C-C bond is reported.

Generation of azomethine imine and its scope in regioselective 1,3-dipolar cycloaddition (DC) of imine with PhIO toward highly substituted Delta(2)-1,2,4-triazoline, 1,2,4-triazole, and their fused, chiral, and sugar-based analogues are demonstrated.

A novel three-port converter (TPC) is proposed to meet the diversity of demand for electrical equipment in this paper. It interfaces a single input power port and two output ports. The TPC can be viewed as bidirectional DC-DC converters. With different operation mode, DC voltages or AC voltage. topology principal analyzed detail. Moreover, mathematic model derived. Then, by considering dynamic ...

Presented in this article is a method for decoupling the speed and flux control of three-phase permanent magnet synchronous motor (PMSM) during an open-circuit fault (OCF) using current controller based on proportional resonant (PR) techniques. The suggested approach relatively simple to implement maintains good operation open circuit. PMSM performance under pre-fault, OCF, post-fault condition...
