Reliability assessment tools are of crucial importance for planning and modernisation of distribution power systems. In recent years there has been an increased deployment of renewable energy. distributed generation. energy storage. electric vehicle. protection device automation and demand response schemes in the distribution networks. All these technologies contribute in their …

Hardware result for 4S-2P- pattern (a) and (b) Similar to simulation. FPA results are verified via hardware prototype under similar operating condition for the following patterns (a). (b). (c) and (d). Experimental results for pattern (a) and (b) with FPA. PSO and P&amp.O methods are shown in Fig. 16 and …

The increasing demand on the power grid makes the dependency on large central generation units infeasible due to the cost and the losses in the transmission lines. Given the challenges facing the grid of today. distributed generation (DG) has been widely seen as an opportunity to facilitate the planning. management …

PCA method based on residues analysis has been established and applied on wind energy conversion system based on doubly fed induction generator diagnosis. An accurate analytical model of the machine has been proposed and simulated to perform the healthy and faulted data for PCA approach need. Several representations of the …

Electric vehicles (EVs) and distributed renewable resources (DRRs) are introduced to achieve three of the most pivotal objectives of this century: using environmentally-friendly energy resources. reliable supply of the load demand. and sustainable development of power systems. To achieve the aforementioned goals. simultaneous utilization of DRRs and EVs should be …

In this paper. a detailed analysis and design procedure of the AHB flyback converter for the universal line-voltage range is provided. The analysis of operation is illustrated by simulation waveforms obtained in Simplis. It is shown that the primaryside switches operate with zero-voltage switching (ZVS). whereas. the secondary-side rectifier operates …

Crystalline-silicon-nanocluster-embedded silicon nitride films were deposited at low temperature using a laser-assisted CVD (LACVD) system with various reactant gas flow rates and assisting laser power densities. The photoluminescence (PL) performances of the resultant films were studied. showing a systematic spectra blue shift. and the enhancement of PL intensity with the …

Smartphone security is challenging and complicated. However. there are some easy ways to improve smartphone security: • Increase security awareness. Like a desktop PC or a laptop. a smartphone can be hacked. infected. or phished. Smartphone users should be aware of potential threats and attacks when installing software19 or authorizing …

Authentication schemes relying on per-packet signature and per-signature verification introduce heavy cost for computation and communication. Due to its constraint resources. smart grid’s authentication requirement cannot be satisfied by this scheme. Most importantly. it is a must to underscore smart grid’s demand for high availability. In this paper. we present …

A new digital distance relaying scheme presented in this paper provides adequate protection to series-compensated double-circuit lines during a simultaneous open conductor and ground fault. The proposed scheme is based on the derivation of the compensated values of impedance using the symmetrical components theory. It measures the correct value of …
