Purpose The purpose of this paper is to test the impact of power (coercive and non-coercive) on supply chain (SC) relationship success. In particular, this paper aims to examine the moderating effect of relationship quality (RQ) on the associations between power bases and relationship success. In turn, RQ and relationship success can impact the operational performance of the suppliers. Design/methodology/approach A survey of 284 Australian suppliers (growers of organic fruits and vegetables) was conducted to elucidate the associations among power, RQ, relationship success and operational performance. Findings RQ was found to only moderate the positive relationship between non-coercive power and relationship success. Moreover, RQ and relationship success were positively related to the suppliers’ operational performance. The findings conform those of previous research in which coercive power is negatively related to the supplier’s perception of relationship success while non-coercive power is positively related to the supplier’s perception of relationship success. Relationship success was found to mediate the relationships between the power bases and operational performance. Research limitations This study only collected data from one-side of the dyad (the suppliers). Another potential limitation is the existence of respondent bias, which can arise when a single respondent is asked to assess both the nature of the relationship and the performance outcomes of the relationship. Practical implications This study highlights the importance for managers to understand the dynamic shaping relationships when they want to signal their influence and RQ in inter-firm relationships associated with the SCs. Originality/value This study applies signaling theory as an alternative theoretical lens that looks into the moderating role of RQ on the associations between power bases and relationship success in the SC. This study argues that when the buyer increasingly develops RQ, the effect of non-coercive power on relationship success diminishes. Both RQ and relationship success positively influence the supplier’s operational performance.

The history of applied superconductor-based equipment in industry, especially in power system, is briefly reviewed. The thesis presents a development of a superconducting magnetic energy storage system for power quality improvement and uninterruptible power supply (PQ/UPS SMES). The configuration of such a system and its control concept are analyzed in full details. Evaluation tests of an SMES system operating on a simple power system are presented and analyzed. They validate the applicability of such a system, as an attractive alternative for power quality improvement and uninterruptable power supply.
The PQ/UPS SMES system as well as the power network has been modeled using Matlab/Simulink simulation environment for convenience. The Simulink models of all relevant components are also presented. Finally, all the evaluation tests are also done in Simulink simulation environment.

In recent years, supply chain management (SCM) has become of great importance as nowadays not only are businesses competing with each other, but so too are suppliers. The main objective of this thesis is to analyse some of the relevant aspects of SCM found in the manufacturing processes and quality control methods of the supply chain in the wind power sector. This is done through a collection of articles which present and analyse real data collected in the field as well as empirical data. The subsequent results reveal that supply chains in the wind power sector are hybrids, where various manufacturing paradigms are in play (lean, agile,leagile and project management) at specific points of the purchasing and manufacturing process. This thesis analyses the lean manufacturing concept inside the wind power sector, revealing the extent to which the lean tools and techniques are applied and the impact they subsequently have on competing priorities. It also examines the difficulties encountered by service providers when attempting to implement lean concepts as well as those resulting from the complex technology required by this highly specialised sector. The thesis also highlights the fact that the widely-used ISO 9001 standard, valid in so many industrial sectors, falls short in sectors dealing with high technological complexity. Furthermore, it sheds light on the perception clients have concerning third-party audits. Lastly, the thesis demonstrates the wind sector’s extensive use of quality tools and techniques when compared to other industrial sectors. This thesis provides the starting point for analysing aspects related to manufacturing and quality management systems in the supply chains of sectors handling high technological complexity, where there is low volume manufacture, high levels of customised and mixed products and irregular demand.
El concepte de la gestió de la cadena de subministrament (SCM) ha anat guanyant importància en els darrers anys, donat que actualment ja no són les empreses les que competeixen entre elles, sinó que són les cadenes de subministrament les que competeixen entre si. El principal objectiu d'aquesta tesi, realitzada sota la modalitat de tesi doctoral per articles, és analitzar per mitjà de dades reals (dades de camp) i empíriques, alguns aspectes rellevants, relacionats amb la fabricació i la gestió de la qualitat, en la cadena de subministrament del sector eòlic. Els resultats d’aquest estudi mostren que la cadena de subministrament del sector eòlic, és una cadena "híbrida", on coexisteixen diferents paradigmes de fabricació (lean, agile, leagile i la gestió per projectes); amb diferents punts de penetració de comanda. Alhora en aquesta tesi, s´analitza el paradigma "lean manufacturing" des de la perspectiva del sector eòlic i ens posa de manifest les dificultats que troben els proveïdors i tecnòlegs del sector a l´hora d'implementar aquest paradigma. També en els resultats d´aquesta tesi es demostra que el popular estàndard de gestió de la qualitat ISO 9001, vàlid per a la majoria de sectors, és un estàndard insuficient quan es tracta d'implementar la gestió de la qualitat en sectors amb una alta complexitat tecnològica. Finalment també aquest treball demostra l'elevat ús de les eines i tècniques de qualitat en el sector eòlic, comparat amb altres sectors industrials. Finalment podem afirmar que aquesta tesi, constitueix un punt de partida per l'anàlisi de cadenes de subministrament en sectors d´alta tecnologia, on la demanda és incerta, amb baixos volums de fabricació i un alt grau de personalització en el “mix” de productes.

Thesis (D.Tech (Engineering Electrical)) - Central University of Technology, Free State, 2005
When Thomas Edison invented his carbon filament lamp in 1879, gas shares fell overnight. A committee of inquiry was set up to examine the future possibilities of the new method of lighting, and had reached the conclusion that electric light in the home was fanciful and absurd. Today electric light burns in practically every house in the civilised world, with many great advances in the production and use of electricity and electric power supplied by various utilities. The objective of the electric utility to deliver pure sinusoidal voltage at fairly constant magnitude throughout their system is complicated by the fact that there are currently loads on the system that produce harmonic voltages, which result in distorted voltages and currents that can adversely impact on the system performance in different ways. Because the numbers of harmonic producing loads have increased over the years, it has become necessary to address their influence, when making any additions or changes to an installation. Quality of supply measurements have long been used to characterise non-linearity on the power system, and have traditionally been measured with expensive portable analysers. A potentially faster, more integrated, and more flexible solution to measure the harmonics with a Supervisory System is accomplished by this research. Any script which aspired to cover in full detail the whole field of a subject so enormous as techniques to measure the quality of electricity supply on a SCADA system, would hardly be practical in less than a few volumes. The pretensions of this research are both modest and of a more immediate value to the reader.

Over the past decades, the concepts and methods for reliability assessment have evolved from analysing the ability of individual components to operate without faults and as intended during their lifetime, into the comprehensive approaches for evaluating various engineering strategies for system planning, operation and maintenance studies. The conventional reliability assessment procedures now receive different perspectives in different engineering applications and this thesis aims to improve existing approaches by incorporating in the analysis: a) a more detailed and accurate models of LV and MV networks and their reliability equivalents, which are important for the analysis of transmission and sub-transmission networks, b) the variations in characteristics and parameters of LV and MV networks in different areas, specified as “generic” UK/Scottish highly-urban, urban, sub-urban and rural network models, c) the relevant requirements for network reliability performance imposed by Regulators on network operators, d) the actual aggregate load profiles of supplied customers and their correlation with typical daily variations of fault probabilities and repair times of considered network components, and e) some of the expected “smart grid” functionalities, e.g., increased use of network automation and reconfiguration schemes, as well as the higher penetration levels of distributed generation/storage resources. The conventional reliability assessment procedures typically do not include, or only partially include the abovementioned important factors and aspects in the analysis. In order to demonstrate their importance, the analysis presented in the thesis implements both analytical and probabilistic reliability assessment methods in a number of scenarios and study cases with improved and more detailed “generic” LV and MV network models and their reliability equivalents. Their impact on network reliability performance is analysed and quantified in terms of the frequency and duration of long and short supply interruptions (SAIFI and SAIDI), as well as energy not supplied (ENS). This thesis addresses another important aspect of conventional approaches, which often, if not always, provide separate indicators for the assessment of system-based reliability performance and for the assessment of customer-based reliability performance. The presented analysis attempts to more closely relate system reliability performance indicators, which generally correspond to a fictitious “average customer”, to the actual “best-served” and “worst-served” customers in the considered networks. Here, it is shown that a more complex metric than individual reliability indicators should be used for the analysis, as there are different best-served and worst-served customers in terms of the frequency and duration of supply interruptions, as well as amounts of not supplied energy. Finally, the analysis in the thesis considers some aspects of the anticipated transformation of existing networks into the future smart grids, which effectively require to re-evaluate the ways in which network reliability is approached at both planning and operational stages. Smart grids will feature significantly higher penetration levels of variable renewable-based distributed generation technologies (with or without energy storage), as well as the increased operational flexibility, automation and remote control facilities. In this context, the thesis evaluates some of the considered smart grid capabilities and functionalities, showing that improved system reliability performance might result in a deterioration of power quality performance. This is illustrated through the analysis of applied automation, reconfiguration and automatic reclosing/remote switching schemes, which are shown to reduce frequency and duration of long supply interruptions, but will ultimately result in more frequent and/or longer voltage sags and short interruptions. Similarly, distributed generation/storage resources might have strong positive impact on system reliability performance through the reduced power flows in local networks and provision of alternative supply points, even allowing for a fully independent off-grid operation in microgrids, but this may also result in the reduced power quality levels within the microgrids, or elsewhere in the network, e.g. due to a higher number of switching transfers and transients.

In reregulated and restructured electricity markets the production and retail of electricity is conducted on competitive markets, the transmission and distribution on the other hand can be considered as natural monopolies. The financial regulation of Distribution System Operators (DSOs) has in many countries, partly as a consequence of the restructuring in ownership, gone through a major switch in regulatory policy. From applying regulatory regimes were the DSOs were allowed to charge their customers according to their actual cost plus some profit, i.e. cost-based regulation, to regulatory models in which the DSOs performance are valued in order to set the allowable revenue, i.e. Performance-Based Regulation (PBR). In regulatory regimes that value performance, the direct link between cost and income is weakened or sometimes removed. This give the regulated DSOs strong cost cutting incentives and there is consequently a risk of system reliability deterioration due to postponed maintenance and investments in order to save costs. To balance this risk the PBR-framework is normally complemented with some kind of quality regulation (QR). How both the PBR and QR frameworks are constructed determines the incentive that the DSO will act on and will therefore influence the system reliability development.

This thesis links the areas of distribution system reliability and performancebased regulation. First, the key incentive features within PBR, that includes the quality of supply, are identified using qualitative measures that involve analyses of applied regulatory regimes, and general regulatory policies. This results in a qualitative comparison of applied PBR models. Further, the qualitative results are quantified and analysed further using time sequential Monte Carlo simulations (MCS). The MCS enables detailed analysis of regulatory features, parameter settings and financial risk assessments. In addition, the applied PBRframeworks can be quantitatively compared. Finally, some focus have been put on the Swedish regulation and the tool developed for DSO regulation, the Network Performance Assessment Model (NPAM), what obstacles there might be and what consequences it might bring when in affect.

Cette thèse de doctorat porte sur les fluctuations temporelles du flux lumineux des lampes LED, ce phénomène portant le nom de papilottement (flicker). Le papillotement est habituellement considéré comme une perturbation en raison de son impact négatif sur la santé. Pour les systèmes d'éclairage à base de diodes électroluminescentes (LED), sa définition vient d'être formalisée dans la norme IEEE 1789:2015 et a été décrite pour les appareils alimentés en courant alternatif (CA). Ce papillotement alternatif résulte des interactions entre l'impédance du réseau, l'onde de tension, les courants harmoniques et le convertisseur de courant alternatif en courant continu (CA - CC). L'alimentation en courant continu est généralement obtenue via des convertisseurs à découpage. Par conséquent, les mêmes facteurs perturbateurs sont également présents sur les réseaux à courant continu. Cette thèse résume les diférences entre les propriétés caractéristiques du papillotement sous alimentation en CA et en CC. Il a été montré dans la littérature et aussi dans cette thèse qu'avec les LED, le facteur clé qui affecte le papillotement réside dans la conception du driver de LED - une partie indispensable des systèmes d'éclairage à LED. Cette thèse décrit une méthodologie d'évaluation de la sensibilité au papillotement des lampes LED sous alimentation en CC et analyse la façon dont cette sensibilité se modifie lorsque les drivers de LED sont simplifiés et adaptés à des alimentations CC. La thèse présente un ensemble d'expériences de mesure visant à déterminer la réaction typique du papillotement des lampes LED à la fois sous alimentation CA et CC. D'autres expériences ont été efectuées pour révéler l'impact de l'adaptation du driver à l'alimentation CC (en enlevant le pont redresseur à diodes). On constate que certaines lampes présentent une meilleure résistance au papillotement, tandis que d'autres lampes présentent une moindre résistance. Ces expériences sont accompagnées de simulations de drivers pour les lampes LED visant à reproduire et à expliquer les résultats des mesures. La thèse décrit en outre une expérience de mesure visant à montrer la sévérité typique de la variation de tension dans un réseau CC à basse tension couplé au CA domestique et son impact sur le papillotement. On conclut qu'un tel système est suisamment robuste pour filtrer les perturbations provenant du CA, mais une interaction indésirable entre la lampe et l'alimentation peut se produire
This dissertation thesis is concerned with temporal fluctuations of the luminous flux of LED lamps, a phenomenon referred to as flicker. Flicker is usually regarded as a disturbance due to its negative impact on human health. For lighting systems based on light emitting diodes (LED), its definition has recently been formalised in norm IEEE 1789-2015 and has been documented on devices supplied with AC voltage. AC flicker results from interactions between network impedance, voltage and current harmonics, and the AC to DC converter. DC supplies are generally obtained by switching converters. Consequently, the same perturbing factors are present on DC networks. The thesis summarises the differences between the characteristic properties of flicker under AC and DC supplies. It has been shown in the literature and also in this thesis that the key factor affecting flicker with LEDs is the design of the LED driver-a necessary part of the LED lighting systems. This thesis describes a methodology for the evaluation of the flicker sensitivity of DC supplied LED lamps and analyses how the sensitivity changes when the LED drivers are simplified and accustomed to DC supply. The thesis presents a set of measurement experiments aimed to determine the typical flicker response of LED lamps both under AC and DC supply. Further experiments were performed to reveal the impact of accustomising the driver to the DC supply (removing the diode rectifier). It was found that some lamps show better flicker immunity while other lamps show worse flicker immunity. These experiments are accompanied by LED driver simulations aiming to reproduce and explain the measurement results. The thesis further describes a measurement experiment aimed to show the typical severity of the voltage fluctuation in a low voltage DC network coupled to AC mains and its impact on the flicker. It is concluded that such a system is robust enough to filter out any perturbations coming from the AC supply, but an undesired interaction between the lamp and the supply may occur

The thesis is for obtaining scientific degree candidate of technical sciences in specialty 05.14.02 – Еlectrical power stations, networks and systems. National Technical University of Ukraine "Kharkov Polytechnic Institute", Kharkov, 2017. The method of calculating the actual values of reactive power flows in power systems of industrial enterprises with varied load was developed in the thesis. This was done by applying the database of automated accounting systems of electric power under conditions, when the balance limit is on the side of high voltage of power transformers and computational metering devices are installed on the side of low voltage. Criteria of reactive power flows optimization for each reactive power source and their combinations were developed. The method of calculating the established operating mode of capacitor bank with the source of higher harmonics was improved by determination the resonant frequency and creation dependence of the impedance absolute value on the number of higher harmonics in the network in order to prevent resonance of currents at higher odd harmonics that are multiples of 50 Hz. The number of working asynchronous electric motors in the group of the same type in real time was determined. Tools and actions which exclude resonance emergence in the power supply system, with working capacitor banks during the startup regime of nonlinear load were developed.

Decarbonization and energy security in Europe are two faces of the same coin. They are both related to the large dependency of the European Union economy on fossil fuels, which today represent around 70% of the total supply of energy. The bulk of these energy resources are imported, with Russia being the largest supplier, accounting for 40% of natural gas and 27% of oil imports. However, fossil fuels are also the primary root cause of greenhouse gas emissions, and the European Union is committed to reduce those by 55% by 2030 (versus 1990). This report is based on the landmark research from the Joint Research Center of the European Commission, the “Integrated Database of the European Energy Sector”, which for the first time mapped actual energy uses for each country within the European Union, across 17 sectors of activity, with data granularity at the level of each process step (or end-use) of each of these sectors. Our approach here has been to systematically review these process steps (or end-uses) and qualify the extent to which they could be electrified, effectively removing the demand for fossil fuels as a result. We have focused only on those process steps where technology was already widely available and for which we evaluated the switch to be relatively easy (or attractive). In other words, we estimated the impact of rapid electrification of “easy to abate” activities. The conclusion of this evaluation is that the share of electricity demand in the final energy mix could jump from around 20% today to 50%, which would drive a reduction in emissions at end-use of around 1,300 MtCO2 /y, as well as a drop in natural gas and oil supply of around 50%. As a result of such transformation, electricity demand would nearly double, with the bulk of that growth materializing in the building sector. Short-term, the challenge of addressing climate targets while providing for energy security is thus intimately connected to buildings. While such transition would certainly require major infrastructure upgrades, which may prove a roadblock to rapid deployment, we find that the combination of energy efficiency measures (notably digital) and distributed generation penetration (rooftop solar) could significantly tame the issue, and hence help accelerate the move away from fossil fuels, with energy spend savings as high as 80% across some building types; a major driver of change. Beyond this, further potential exists for electrification. Other measures on the demand-side will include deeper renovations of the industrial stock (notably in the automotive, machinery, paper, and petrochemical industries for which our current assessment may be underestimated) and further electrification of mobility (trucks). The transition of the power system away from coal (and ultimately natural gas) will then also play a key role, followed ultimately by feedstocks substitution in industry. Some of these transitions are already on the way and will likely bring further improvements. The key message, however, is that a significant opportunity revolves around buildings to both quickly decarbonize and reduce energy dependencies in Europe. Rapid transformation of the energy system may be more feasible than we think. We notably estimate that, by 2030, an ambitious and focused effort could help displace 15% to 25% of natural gas and oil supply and reduce emissions by around 500 MtCO2 /y (note that these savings would come on top of additional measures regarding energy efficiency and flexibility, which are not the object of this study). For this to happen, approximately 100 million buildings will need renovating, and a similar number of electric vehicles would need to hit the road.
