Full-Scale Implementation of RES and Storage in an Island Energy System
inventions Article Full-Scale Implementation of RES and Storage in an Island Energy System Konstantinos Fiorentzis , Yiannis Katsigiannis and Emmanuel Karapidakis * Department of Electrical and Computer Engineering, Hellenic Mediterranean University, GR-71004 Heraklion, Greece; kfi[email protected] (K.F.); [email protected] (Y.K.) * Correspondence: [email protected]; Tel.: +30-2810-379-889 Received: 10 September 2020; Accepted: 29 October 2020; Published: 30 October 2020 Abstract: The field of energy, specifically renewable energy sources (RES), is considered vital for a sustainable society, a fact that is clearly defined by the European Green Deal. It will convert the old, conventional economy into a new, sustainable economy that is environmentally sound, economically viable, and socially responsible. Therefore, there is a need for quick actions by everyone who wants to move toward energy-efficient development and new environmentally friendly behavior. This can be achieved by setting specific guidelines of how to proceed, where to start, and what knowledge is needed to implement such plans and initiatives. This paper seeks to contribute to this very important issue by appraising the ability of full-scale implementation of RES combined with energy storage in an island power system. The Greek island power system of Astypalaia is used as a case study where a battery energy storage system (BESS), along with wind turbines (WTs), is examined to be installed as part of a hybrid power plant (HPP). The simulation’s results showed that the utilization of HPP can significantly increase RES penetration in parallel with remarkable fuel cost savings. Finally, the fast response of BESS can enhance the stability of the system in the case of disturbances. -

Energy provision for the urban poor country case study: South Africa ii EXECUTIVE SUMMARY Urban poverty is a severe and growing problem in South Africa. The rate of urbanisation is increasing and the new democratic government and local authorities are struggling with a lack of capacity and inadequate funds to address the historic backlog of housing and services, health and education for the 50% of the population who are poor and currently without these facilities. The liberalisation of the economy and opening up of the previously closed and protected markets has seen the number of unemployed increasing while the population continues to grow. South Africa has a relatively strong industrial base and has Eskom, the world’s fifth largest electricity utility. Eskom generates electricity largely from the country’s substantial coal reserves. -
Airborne Wind Energy Systems: Modelling, Simulation and Trajectory Control
FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Airborne Wind Energy Systems: Modelling, Simulation and Trajectory Control Gonçalo Barros da Silva Mestrado Integrado em Engenharia Eletrotécnica e de Computadores Supervisor: Fernando Arménio da Costa Castro e Fontes Co-Supervisor: Luís Tiago de Freixo Ramos Paiva July 30, 2018 © Gonçalo Barros da Silva, 2018 Resumo Atualmente a energia eólica é essencialmente extraída on-shore através de turbinas éolicas com algumas dezenas de metros. No entanto, é off-shore e a elevadas altitudes que o vento é mais forte e, sobretudo, mais consistente. Neste contexto, soluções inovadoras no âmbito dos AWES têm vindo a ser apresentadas. Com esta dissertação pretende-se estudar um destes sistemas, que envolve um kite ligado a um gerador através de um cabo. À medida que o kite se eleva por força do vento, o cabo é desenrolado, fazendo acionar o gerador, produzindo assim energia. Posteriormente, o cabo é recolhido e, de seguida, o processo repete-se. O sucesso destes sistemas é suportado pelo facto de que a força de lift do kite é proporcional ao quadrado da velocidade aparente do vento. O objectivo principal desta dissertação é desenvolver um algoritmo de seguimento de trajetória que permita ao kite seguir um caminho pré-definido durante a fase de produção. A trajetória deve ser definida de forma a que o kite se mova maioritariamente numa direção perpendicular à velocidade do vento, maximizando assim a produção de energia. Neste contexto, o modelo dinâmico 3D do Kite é descrito. De seguida, são realizadas simu- lações com versões 2D simplificadas do modelo, com o objetivo de o validar. -

Impofu East Wind Farm Red Cap Impofu East (Pty) Ltd Avifaunal scoping study September 2018 REPORT REVIEW & TRACKING Document title Impofu East Wind Farm- Avifaunal Scoping study Client name Kim White Aurecon Status Draft report-for client Issue date September 2018 Lead author Jon Smallie – SACNASP 400020/06 Internal review Luke Strugnell – SACNASP 400181/09 WildSkies Ecological Services (Pty) Ltd 36 Utrecht Avenue, East London, 5241 Jon Smallie E: [email protected] C: 082 444 8919 F: 086 615 5654 2 EXECUTIVE SUMMARY Red Cap Energy (Pty) Ltd successfully developed the 80 MW Kouga Wind Farm and the 111 MW Gibson Bay Wind Farm in the Kouga Local Municipality, Eastern Cape, South Africa. This area lies on a section of coastal plain in close proximity to the ocean on either side which results in excellent wind conditions and low levels of turbulence, making it ideal for wind farm development. Red Cap has now signed option agreements on approximately 15 500 ha of new undeveloped private farmland, known as the “Impofu Wind Farms” Project. The 3 wind farms will ultimately consist of up to a maximum total of 120 turbines and associated infrastructure and will connect to the grid close to Port Elizabeth. The Impofu East Wind Farm, the subject of this report, consists of up to 41 turbines. We have conducted an initial assessment of the site, a screening assessment and a full (four seasons) pre-construction bird monitoring programme on site. The most important of our findings are as follows: We make the following conclusions regarding the avifaunal community and potential impacts of the Impofu East Wind Farm: » We classified nine species as top most priority for this assessment: Denham’s Bustard, White- bellied Korhaan, Blue Crane, Black Harrier, African Marsh-Harrier, Martial Eagle, African Fish- Eagle, Jackal Buzzard and White Stork. -

Climate Change Impacts on Southern African Wind Energy Resources
Projected potential for wind energy generation in South Africa under conditions of climate change by Lynette Herbst Submitted in partial fulfilment of the requirements for the degree MASTER OF SCIENCE in the Faculty of Natural and Agricultural Sciences University of Pretoria Pretoria August 2015 i DECLARATION I, Lynette Herbst, declare that the dissertation, which I hereby submit for the degree Master of Science at the University of Pretoria, is my own work and has not previously been submitted by me for a degree at this or any other tertiary institution. ___________________ _________________ SIGNATURE DATE ii Projected potential for wind energy generation in South Africa under conditions of climate change Lynette Herbst Promoter: Prof. Hannes Rautenbach Department: Geography, Geoinformatics and Meteorology Faculty: Natural and Agricultural Sciences University: University of Pretoria Degree: Master of Science in Environmental Management SUMMARY The South African wind energy sector is developing rapidly with numerous wind energy facilities currently being commissioned. According to the Intergovernmental Panel on Climate Change (IPCC), some risks and opportunities for wind power generation as a result of climate change could be anticipated in future. The objectives of this study were therefore to: a. determine whether seasonal near-surface winds over South Africa, as generated by a Regional Climate Model (RCM) using boundary conditions supplied from coupled Global Circulation Models (GCMs), during a reference period of 1981 to 2005, are realistically represented; b. establish whether differences exist between seasonal near-surface winds calculated for the reference period (1981-2005) versus a projected period of 2051 to 2075, incorporating two future Representative Concentration Pathways (RCP4.5 and RCP8.5); c.
