A MicroGrid can be defined as an electrical network of small modular distributed generating units (whose prime movers may be photovoltaics, fuel cells, micro turbines or small wind generators), energy storage devices and controllable loads. A MicroGrid can operate in grid-connected or islanded mode and hence increase the reliability of energy supplies by disconnecting from the grid in the case ...

The IEEE 1588 precision time protocol (PTP) time-setting mode of operation can be used to dramatically improve the quality of time-based systems that rely on a physical layer syntonization source in addition to PTP. Based on the standardized PTP protocol and common network frequency distribution techniques, the PTP time-setting mode of operation is capable of distributing time over packet-based...

This study communicates a single-stage, 3-?, rooftop solar photo voltaic (PV) and grid compatible tri-capacity battery charger (TBC) topology for home-based low voltage direct current nanogrid (LVDC NG). The proposed architecture performs power factor correction drawing sinusoidal currents at unity factor, single-stage rectification of 3-? voltages constant mode charging simultaneously. employe...

In recent times, interest in renewable energy-based Distributed Generation (DG) is increasing rapidly. These sources are connected to AC bus through inverter interface. During islanded mode, output voltage and frequency of should be properly regulated for stable operation it done by applying control action on inverter. The paper presents a strategy controlling output. It deals with active power...

BACKGROUND Problematic scar contractures are frequently observed following extensive (burn) wounds. In this study, the authors investigated the applicability of islanded and nonislanded perforator-based interposition flaps as a technique for release of scar contracture. METHODS Patients requiring surgery for scar contracture release were included. Preoperatively, a suitable perforator was ide...

Microgrids active characteristics such as grid-connected or islanded operation mode, the distributed generators with an intermittent nature, and bidirectional power flow in distribution lines lead to malfunction of traditional protection schemes. In this article, impedance-based fault detection scheme is proposed main microgrids by applying equivalent circuits for doubly-fed lines. scheme, rela...

Massive integration of power electronic devices with multiple control schemes in a wide frequency range pose new challenges regarding systems stability and reliability. Interactions between the fast loops or passive elements grid, have been reported literature led to introducing type stability: Fast-Interaction Converter-driven Stability (FICDS). In this paper, factors affecting FICDS, such as ...

Abstract: This paper presents a seamless transition method for a droop-controlled inverter. The droop control is suitable to make the inverter work as a voltage source in both islanded and grid-connected modes, however, the transfer between theses modes can result in a big inrush current that may damage the system. The proposed method allows the droop-controlled inverter to improve the transien...

We propose a block-cipher mode of operation, EAX, for solving the problem of authenticated-encryption with associated-data (AEAD). Given a nonce N , a message M , and a header H , our mode protects the privacy of M and the authenticity of bothM andH . StringsN ,M , andH are arbitrary bit strings, and the mode uses 2djM j=ne + djHj=ne + djN j=ne block-cipher calls when these strings are nonempty...
