Energy Injection By Disbributed Generation For Enhancement Of Voltage Profile In Swer Systems, Kashem M. Muttaqi, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

A system with Distributed Generation (DG) has greater load carrying capacity and can correct for a poor voltage profile during peak loading. This paper addresses the loading patterns of rural feeders and the relative effectiveness of real and reactive injection to support voltage profile in Single Wire Earth Return (SWER) systems. Real and reactive injection on a SWER network has been investigated and required energy for voltage enhancement estimated. DG with real and reactive injection (DG-PQ) using Q priority (DG-QPQ) can drastically reduce fuel and energy requirements compared to the amount required by proportional use of real and reactive power ...

Minimising Voltage Deviation In Distribution Feeders By Optimising Size And Location Of Distributed Generation, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

A new emerging trend of distribution networks is to use small generating units, known as distributed generation (DG), operating in parallel with the main grid. This kind of distribution networks has enabled DG to support power systems in fulfilling their requirements to increase power output as well as quality of power supply. DG has potential to alter power flows, system voltages, and the system performance. In order to maximise benefits from the DG system, proper DG planning is necessary. Determining an optimal DG size and its DG location are critical issues that are addressed in this paper. The main purpose ...


Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich Jan 2005

Minimising Power Losses In Distribution Systems With Distributed Resources, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Attempts to reduce electricity cost, together with improving the efficiency of distribution systems, have led power utilities to dealing with the problem of power loss minimisation. Although losses in the system can never be entirely eliminated, they can be controlled and minimised in several ways. Research conducted in the last few decades has proven that an inclusion of Distributed Resources (DR) into distribution systems considerably lowers the level of power losses. Moreover, the choice of DR is even more attractive since it provides not only benefits in power loss minimisation, but also a wide range of other advantages including environment ...


Hierarchical Bayesian Modeling Of The Movement Of Ice Streams, L M. Berliner, Noel A. Cressie, Kenneth Jezek, Yongku Kim, Calvin Lam Jan 2005

Hierarchical Bayesian Modeling Of The Movement Of Ice Streams, L M. Berliner, Noel A. Cressie, Kenneth Jezek, Yongku Kim, Calvin Lam

Faculty of Engineering and Information Sciences - Papers: Part A

Modern studies of the behaviors of glaciers, ice-sheets, and ice-streams rely heavily on both observations and physically based models. Data acquired via remote-sensing provide critical information on geometry and movement of ice over large sections of the Antarctic and Greenland. Though these datasets represent significant advances in terms of spatial coverage and the range of processes we can observe, the physical systems to be modeled are nevertheless incompletely observed. Uncertainties associated with measurement errors are also present. In addition, physical models are also subject to uncertainties. Hence, there is a need for combining observations and models in a fashion that ...


Encapsulation Of Validation Tests In The Esp-R Simulation Program, Paul Strachan, Georgios Kokogiannakis, I Macdonald Jan 2005

Encapsulation Of Validation Tests In The Esp-R Simulation Program, Paul Strachan, Georgios Kokogiannakis, I Macdonald

Faculty of Engineering and Information Sciences - Papers: Part A

It is well recognised that validation of dynamic building simulation programs is a long-term complex task. There have been many large national and international efforts that have led to a well-established validation methodology comprising analytical, inter-program comparison and empirical validation components, and a significant number of tests have been developed. As simulation usage increases, driven by such initiatives as the European Energy Performance of Buildings Directive, such tests are starting to be incorporated into national and international standards. Although many program developers have run many of the developed tests, there does not appear to have been a systematic attempt to ...

Maximising Voltage Support In Distribution Systems By Distributed Generation, An D. T Le, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Rapidly increasing in the demand of electricity along with recently advances in distributed generation (DG) technologies have sparked a new interest in utilisation of DG sources. However, there are a number of technical issues regarding to the installation of DG, since DG connection significantly affects existing network configuration and operation, especially for system with high level of DG penetration. To achieve maximum voltage support from DG utilisation, methodologies related to DG placement and DG operation are developed in this paper. Technique to optimise voltage improvement by effectively injecting active and reactive power of DG is developed based on voltage sensitivity ...

Dynamics Of A Hydro-Wind Hybrid Isolated Power System, M Aktarujjaman, Kashem M. Muttaqi, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Implementation of Distributed Generation (DG) can improve power quality and reliability, and guarantee continuity of power supply. This paper addresses the issue of continuity of power supply especially for isolated communities. A part of a network can be electrically isolated from the main grid when the grid fails to supply power due to a fault in the network or unavailability of power generation. In this paper, a mini hydro-wind hybrid power system is considered, and operation and control of the hybrid system during connecting it with the grid as well as its operation in the isolated condition are investigated. The ...


Design Of Monolimb Using Finite Element Modelling And Statistics-Based Taguchi Method, Winson Lee, Ming Zhang Jan 2005

Design Of Monolimb Using Finite Element Modelling And Statistics-Based Taguchi Method, Winson Lee, Ming Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

Background. Monolimb is a transtibial prosthesis having the socket and shank molded into one piece of thermoplastic material. If properly designed, the shank of a monolimb can have a controlled deflection during walking which simulates the ankle joint motions to some extent. However, there is no clear guidance for the design of monolimb considering the dilemma between shank flexibility and structural integrity. Methods. Finite element analysis was used to simulate structural tests based on ISO10328 on monolimbs of different configurations. Statistics-based Taguchi method was employed to identify the significance of each design factor in controlling the deformation and stress within ...

Also, X-ray diffraction (XRD) was used to analyze the crystal structure of the samples.


A Quasi-Dynamic Nonlinear Finite Element Model To Investigate Prosthetic Interface Stresses During Walking For Trans-Tibial Amputees, Xiaohong Jia, Ming Zhang, Xiaobing Li, Winson Lee Jan 2005

A Quasi-Dynamic Nonlinear Finite Element Model To Investigate Prosthetic Interface Stresses During Walking For Trans-Tibial Amputees, Xiaohong Jia, Ming Zhang, Xiaobing Li, Winson Lee

Faculty of Engineering and Information Sciences - Papers: Part A

Background. To predict the interface pressure between residual limb and prosthetic socket for trans-tibial amputees during walking. Methods. A quasi-dynamic finite element model was built based on the actual geometry of residual limb, internal bones and socket liner. To simulate the friction/slip boundary conditions between the skin and liner, automated surface-to-surface contact was used. Besides variable external loads and material inertia, the coupling between the large rigid displacement of knee joint and small elastic deformation of residual limb and prosthetic components were also considered. Results. Interface pressure distribution was found to have the same profile during walking. The high ...

Subquotients Of Hecke C*-Algebras, Nathan Brownlowe, Nadia Larsen, Ian Putnam, Iain Raeburn Jan 2005

Subquotients Of Hecke C*-Algebras, Nathan Brownlowe, Nadia Larsen, Ian Putnam, Iain Raeburn

Faculty of Engineering and Information Sciences - Papers: Part A

We realize the Hecke C*-algebra CQ of Bost and Connes as a direct limit of Hecke C*-algebras which are semigroup crossed products by NF, for F a finite set of primes. For each approximating Hecke C*-algebra we describe a composition series of ideals. In all cases there is a large type I ideal and a commutative quotient, and the intermediate subquotients are direct sums of simple C*-algebras. We can describe the simple summands as ordinary crossed products by actions of ZS for S a finite set of primes. When |S|=1, these actions ...


Conditional Ordering Using Nonparametric Expectiles, Yves Aragon, Sandrine Casanova, Raymond Chambers, Eve Leconte Jan 2005

Conditional Ordering Using Nonparametric Expectiles, Yves Aragon, Sandrine Casanova, Raymond Chambers, Eve Leconte

Faculty of Engineering and Information Sciences - Papers: Part A

Expectile regression, and more generally M-quantile regression, can be used to characterise the relationship between a response variable and explanatory variables when the behaviour of "nonaverage" individuals is of interest. The aim is to demonstrate how an individual expectile-order, based on nonparametric estimation of the expectile regression function, can also be used to define a conditional ordering of the individual's value relative to the values of other members of a data set. The relationship between contextual, or "grouping", variables and this ordering can then be investigated. In particular, we propose five estimators of expectile-order, which we compare via simulation ...


Bayesian Analysis For Penalized Spline Regression Using Winbugs, Ciprian Crainiceanu, David Ruppert, M. P. Wand Jan 2005

Bayesian Analysis For Penalized Spline Regression Using Winbugs, Ciprian Crainiceanu, David Ruppert, M. P. Wand

Faculty of Engineering and Information Sciences - Papers: Part A

Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression. Bayesian inference for nonparametric models enjoys the flexibility of nonparametric models and the exact inference provided by the Bayesian inferential machinery. This paper provides a simple, yet comprehensive, set of programs for the implementation of nonparametric Bayesian analysis in WinBUGS. Good mixing properties of the MCMC chains are obtained by using low-rank thin-plate splines, while simulation times per iteration are reduced ...

Reinforcement Of Macroscopic Carbon Nanotube Structures By Polymer Intercalation: The Role Of Polymer Molecular Weight And Chain Conformation, C J. Frizzell, Marc In Het Panhuis, D H. Coutinho, K J. Balkus, A Minett, W J. Blau, J N. Coleman

Faculty of Engineering and Information Sciences - Papers: Part A

Novel polymer nanotube composites were fabricated by intercalating poly(vinylpyrrolidone) into Buckypaper from solution. This was carried out for both low (10kg∕mol) and very high (1.3Mg∕mol) molecular weight polymers. Measurements of the polymer mass uptake as a function of time allowed the calculation of diffusion coefficients as 1.66×10−9cm2∕s and 3.08×10−12cm2∕s for the low and high molecular weight strands, respectively. Taking into account the molecular weights, comparison of these coefficients suggests that each polymer type undergoes a different mode of diffusion: normal diffusion for the 10kg∕mol polymer, but reptation ...


Drag Reduction In A Flat-Plate Turbulent Boundary Layer Flow By Polymer Additives, Shu-Qing Yang, G Dou Jan 2005

Drag Reduction In A Flat-Plate Turbulent Boundary Layer Flow By Polymer Additives, Shu-Qing Yang, G Dou

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents a theoretical study on the velocity distribution and the friction factor of boundary layer flows with polymer additives starting from the concept of “stress deficit.” A novel method of order of magnitude analysis is developed, which converts the governing equations of boundary layer flow into a solvable ordinary differential equation, thus the total shear stress distribution is obtained, then the formulas for the mean velocity profiles and the friction factor for a boundary layer flow are derived after introducing appropriate expressions for the “effective viscosity” and the thickness of viscous sublayer. The derived velocity equation is able ...

Faculty of Engineering and Information Sciences - Papers: Part A

A set of innovative active pixel architectures has been conceived and implemented in standard CMOS technology. Active circuits are introduced into the pixel, to increase S/N ratio and to perform basic signal processing. Testing of such devices, however, becomes critical, due to the circuit relative complexity and to the need of accurately evaluating timing and position of the impinging radiation. A test strategy has thus been devised, exploiting a NIR laser source, which has been carefully characterized and tuned. The NIR laser allows for emulating, in a much more controllable fashion, a MIP event. This allow for validation of ...

A Post-Compilation Register Re-Assignment Technique For Improving Hamming Distance Based Code Compression, Montserrat Ros, Peter Sutton Jan 2005

A Post-Compilation Register Re-Assignment Technique For Improving Hamming Distance Based Code Compression, Montserrat Ros, Peter Sutton

Faculty of Engineering and Information Sciences - Papers: Part A

Code compression is a field where compression ratios between compiler-generated code and subsequent compressed code are highly dependent on decisions made at compile time. Most optimizations employed by compilers tend to focus on parameters such as program performance, minimizing resource dependencies and sometimes the option of reducing code size. This paper describes a post-compilation technique for the greedy reassignment of general purpose scratch registers to improve Hamming distance based code compression. The code translation renumbers registers based on the frequency of registers used by isomorphic instructions and employs a Gray coding scheme to reduce Hamming distances between similar instructions. Register ...
