Vindkraft i relation till andra intressen om mark : Elbehov i Norrbottens länNäsholm, Henrik January 2023 (has links)
The electricity demand in Norrbotten County is expected to increase from 8 TWh in 2019 to 107 TWh in 2050. A contributing role to the large electricity demand in Norrbotten County is that LKAB will make large investments within the company. LKAB's electricity needs will increase from 2 TWh in 2020 to 50 TWh in 2040. LKAB believes that wind power is one of the best options for getting energy quickly at a low cost. The land construction, which is a large wind power project in Piteå municipality, was planned to build 1101 wind turbines that would produce 10–12 TWh per year. To build all the wind turbines, a land area of 450 square kilometers needs to be used. If you start from the ground construction, they will need 5000-5500 wind turbines to produce 50 TWh of energy. The area that needs to be used to build 5000-5500 wind turbines is then 2000-2,250 square kilometers. This means that future wind power installations will need access to large areas of land. But there are other interests that also have an interest in the same land and may have to compete with wind power for land in the future. The purpose of the study is to investigate and analyze which other interests are competing with potential new wind power establishments for land in Norrbotten County and to contribute to future wind power projects being sustainable. The result shows that there are other interests that are also interested in land in Norrbotten County. The result also shows that trade-offs are made between different interests and that wind turbines have an impact on us humans. The interests brought out in the study and which may compete with wind power for land in the future are, outdoor life, nature conservation, reindeer husbandry, national park, nature reserve, water protection area, natura 2000, the Armed Forces, unbroken mountains, cultural environment conservation, commercial fishing, facilities for communication and human interests.

The development of a decision-making matrix to address the South African power crisisDarby, Rene 12 1900 (has links)
Thesis (MBA (Business Management))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: This research report discusses the development of a decision-making matrix during power crises. South Africa comes from a situation of excess supply and is currently in a situation where electricity demand exceeds supply. This report will provide the background of how the current electricity crisis came to be and what the future of the industry will look like. As electricity shortages is a worldwide issue, the study will explore international countries' experience of supply shortages and extract
lessons learnt and best practices that can be applied in the South African context. The study reviews available solutions that exist to address the electricity crisis in South Africa and explores alternative energy sources that could be applied in South Africa. To establish an effective decision making tool for electricity shortage response mechanisms, the key decision making criteria are discussed and explained. A decision making matrix brings together all the available solutions and decision-making
criteria based on the decision maker's relative importance placed on the considerations and the resultant impact on these considerations. The results of the decision-making matrix directs the decision maker to the least negative impact solution and provides a basis on which to make sound decisions during a time when quick and effective decisions will determine the success and sustainability of the power system. / AFRIKAANSE OPSOMMING: Hierdie navorsingsverslag bespreek die ontwikkeling van 'n besluitnemingsmodel wat aangewend kan word tydens kritiese tekorte in elekrisiteitsvoorsiening op 'n nasionale basis. Die elektrisiteits- ontwikkelingsvermoë in Suid-Afrika het beweeg vanaf 'n oorskot na 'n posisie waar daar nie in die aanvraag voorsien kan word nie. Hierdie navorsingsverslag skets die agtergrond van wat aanleiding gegee het tot die
huidige elektrisiteitskrisis en wat die toekoms inhou vir elektrisiteitsvoorsiening in die algemeen. Die gebrek aan elektrisiteitsontwikkelingsvermoë is 'n wêreldwye tendens en die lesse wat ander lande geleer het tesame met hul beste praktyke word oorweeg binne
die Suid-Afrikaanse konteks. Beskikbare oplossings wat op die manier geidentifiseer word, word ontleed, tesame met moontlike alternatiewe energiebronne wat in Suid-Afrika aangewend kan word. Die kern besluitnemingskriteria word bespreek en ontleed om sodoende 'n proses daar te stel waarvolgens die besluitnemingsmodel wat die mees effektiewe oplossing in tye van kritiese elektirsiteitstekorte sal voortbring te ontwikkel.
Al die beskikbare en werkbare opsies tydens die periode van elektristeitstekorte word saamgevoeg binne die besluitnemingsmodel om die toepaslikheid daarvan op te weeg teenoor die relatiewe gewig wat die besluitnemer toeken aan al die onderliggende faktore. Die besluitnemingsmodel ondersteun die besluitnemer om, tydens 'n krisis in elektrisiteitsvoersiening, 'n vinnige en doeltreffende besluit te neem wat die minste negatiewe impak het op ekonomiese aktiwiteite en die sukses en stabiliteit van die elektrisiteitsvoorsieningsnetwerk waarborg.

A New Market Logic Approach for Achieving Load Profile Smoothness in the Swedish Electricity Market : Incorporating Inventory Management Principles for Optimized Battery OperationAntoniadis, Theodoros January 2022 (has links)
As the demand for imported electricity from the grid continues to increase in Södermanland county, achieving a smoother load profile for the overall imports becomes very critical. The utilization of batteries in every type of a company’s infrastructure aims to provide a backup solution when the electric network’s capabilities are unable to support demand for high imported capacities. The current degree project aims to analyse the impact of a New Market Logic, which encourages the prospective stakeholders of a future industrial park to invest in upgrades of their energy infrastructures. Interviews with company employees and literature reviews were used to analyse the conventional energy system according to its power-generating entities, distribution operators, and market norms of electricity. Microsoft Excel was used to simulate a model that aligns with the research goal specifications. Sensitivity analysis was also carried out to provide a better understanding of how different aspects impact the economics and the energy flows. Inventory management theory principles were applied to the design of an integrated battery charging algorithm with the goal of achieving a smother load profile while keeping a low battery capacity. The results indicated a smoother load profile of the companies, followed by a lower intensity in fluctuations during hourly peaks. Further, the author observed a positive economic impact on the yearly cash flows of the companies accompanied with a sustainable investment cost. This was particularly evident when the charges were adjusted according to the norms introduced by the New Market Logic. / <p>This thesis is a part of the integrated Master's studies program at the Department of Mechanical Engineering at the Aristotle University of Thessaloniki. The author had the privilege of completing it in Sweden through the Erasmus+ Exchange program. </p>
