In this paper, after a brief introduction on the developed plug-and-play (PnP) process monitoring and control architecture, a decentralized plug-and-play (PnP) process monitoring system for large-scale industrial processes is studied. And then, aiming at lower online computational load and more flexible industrial implementation, a decentralized adaptive configuration technique is further developed...
Transport sector could play a relevant role in future energy decarbonisation pathways contributing to energy consumption and pollutant emissions reduction. Planning in the transport sector requires that policy makers be supported with scientifically sound tools, which are able to take into account the peculiar aspects of transport system analyses, especially at urban scale. One of these peculiarities...
This paper presents a proposed cuckoo search algorithm with interactive learning and linear decreasing probability strategy (CSIL) to solve the economic dispatch problem with power balance, prohibited operating zones, valve point effect, and ramp rate. In the new approach, interactive learning strategy helps the nest to exchange good information from each other. Meanwhile, the linear decreasing probability...
The purpose of this paper is to provide insight into Energy storage devices which will transform the way the world utilises, controls and dispatches electrical energy in the near future. With the increasing amount of renewable energy being injected into transmission and distribution grids and the rapid uptake of rooftop solar photo-voltaic installations in households, energy storage is unlocking a...
The development of a rapidly deployable modular electric generator based on plug-in hybrid vehicle DC architectures provides a highly reliable DC microgrid for use in applications with unstable infrastructure or highly sensitive loads. The result is the commercial production of early stage prototype units built by Schneider Electric with onboard energy storage, combustion generator and rapid interconnects...
High voltage laboratories are designed to have sufficient clearances to avoid undesired flashovers from generator surfaces. However, numerous factors influence the characteristics of breakdown in air, including ambient conditions such as temperature, pressure, and humidity. If the laboratory environment is not adequately controlled, ambient conditions could deviate as a function of elevation and result...
This paper proposes two classes of new pseudorandom number generators from block ciphers, called HTR and HBC. They are provably secure in the PRG-CIA (pseudorandom generator against chosen-input-attacks) sense, assuming that the underlying block cipher is a secure pseudorandom permutation (PRP). HTR is a parallel structure, while HBC is a cascade structure. Therefore, the implementation efficiency...
This paper presents results of a heuristic optimization method for parameterization of decentral reactive power control, which can be used to improve static voltage quality in distribution grids. With an optimized Q(V)-curve it is possible to significantly reduce the additional reactive energy and accomplish lower losses in the grid while keeping the voltage within the specified limits. In this paper...
This paper analyses the existing protection scheme of a real distribution system with distributed generators, in Greece. Network protection utilizes three successive reclosers at the main trunk and fuses at the laterals. The generating units are protected by overcurrent and voltage/frequency relays. The analysis focuses on the fault-ride-through capability of the generating units and proposes the...
Distribution networks are increasingly hosting embedded generators, most of them converting renewable energy primary sources. These units are usually interfaced with the main network by means of static power converters. Grid codes have recently introduced stabilizing functions to engage distributed plants in supporting the main system stability during network events and consequent voltage/frequency...
The paper presents a model based analysis of different network charging schemes with respect to their ability to provide good incentives for prosumers with or without storage as well as to achieve a fair distribution of network cost between different network levels with varying shares of distributed generation. It finds charging schemes based on net energy or net peak to reflect the effects of generation...
In countries with Capacity Mechanisms in place, where Explicit Interconnector Participation model is to be used, one of the key market design questions to be answered is how the amount of interconnector capacity that is allowed to participate in the auctions should be determined. This paper argues for an interconnector capacity de-rating approach. In order for the de-rating factor to be representative...
In this study, an analysis of the effect of the electrostatic discharge (ESD) gun grounding strap on the generated ESD stress waveform is presented. The reference ESD waveform is measured using the standard calibration setup of the IEC 61000-4-2 standard for the different (round, short and long) configurations of the grounding strap. The post processing analysis shows that increasing the length of...
Engaging MV and LV end-users in providing ancillary services to the main grid is a very interesting scenario, in which the traditional interactions between Distribution System Operators and customers are significantly modified. In this work, a novel pricing structure is introduced to investigate how the behaviour of active end-users, including local generation and storage systems, could be influenced...
We formulate two coordination mechanisms between local and centralized electricity markets. The first one is a centralized mechanism ruled by the national market operator and formulated as a standard constrained optimization problem. The second one is a decentralized mechanism, governed by local market operators that interact with a central market operator. In both cases, conventional generators submit...
An ultra low power CMOS voltage reference has been developed in a low-cost CMOS 130 nm technology. The design benefits in particular from using only one standard CMOS process without incorporating any resistors, op-amp, bipolar transistor or other CMOS processes. The circuit draws ultra low current of 230 nA from supply voltage of 1.2 V. The proposed circuit generates output an voltage of 698.5 mV...
This paper describes a novel sub-threshold voltage reference generator suitable for very low power and very low voltage wearable systems. Indeed, the circuit, designed and extensively simulated in a standard 0.18-μm CMOS technology, generates a 51.3-mV output voltage with a nominal supply voltage of 0.5 V and consumes as low as 185 nW. Design optimisation and a first order temperature compensation...
In this paper we present an event-based methodology for the control of the depth of hypnosis in general anesthesia. The control system is based on the implementation of an event generator with strong noise filtering capabilities together with a PIDPlus controller and considers both the administration of propofol and remifentanil in order to obtained a desired level of the bispectral index scale. Simulation...
The electrical power generation and distribution system for one of the Platform (Platform ‘A’) was designed different from earlier fixed drilling and production platforms in the North Sea. The main difference is that there is no dedicated emergency generator on board. Instead each of the three main generators has been upgraded to a standard normally associated with emergency sets. This provides higher...
Now a day, need for fast accessing of data is increasing with the exponential increase in the security field. QR codes have served as a useful tool for fast and convenient sharing of data. But with increased usage of QR Codes have become vulnerable to attacks such as phishing, pharming, manipulation and exploitation. These security flaws could pose a danger to an average user. In this paper we have...
