  • 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.

The U.S. Department of Energy’s (DOE’s) Wind Energy Technologies Office (WETO) focuses on The Block Island Wind Farm, the first U.S. offshore wind farm, enabling industry growth and U.S. competitiveness by represents the launch of an industry that has the potential supporting early-stage research on technologies that to contribute significantly to a reliable, stable, and affordable enhance energy affordability, reliability, and resilience energy mix.

  • 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.

Some of the principles addressed in this technology review may also apply to other hybrid energy systems (see Chapters 2 and 7 of the main report of the Quadrennial Technology Review). The main purpose of an N-R HES is to use nuclear energy, variable renewable energy sources such as wind and solar, biomass energy, or others as clean energy sources to support electrical and thermal duties of electricity generation, fuels production, chemical synthesis, and other industrial processes at competitive prices and to thus decrease greenhouse gas emissions (GHG) by the electricity, transportation, and industry sectors. Such hybrids would differ substantially from traditional systems that typically use just one or perhaps two energy sources (e.g., biomass co-firing with coal) to produce electricity and sometimes useful heat (cogeneration systems).

During the last decade of the 20th century, grid-connected wind capacity worldwide has doubled approximately every three years. Due to the fast market development, wind turbine technology has experienced an important evolution over time. Some of the countries with wind energy programmes are listed together with a discussion of how widely this energy source might be used. It concluded that, wind power is the fastest growing energy technology at the turn of the millennium, and will continue to grow for the foreseeable future due to it is abundant, domestic, inexhaustible and clean energy source. Keywords wind energy, renewable energy, greenhouse gases, economics, wind turbines The power of the wind has been utilized for at least the past 3000 years. Until the early 20th century wind power was used to provide mechanical power to pump water or to grind grain. At the beginning of modern industrialization, the use of the fluctuating wind energy resource was substituted by fossil fuel fired engines or the electrical grid, which provided a more consistent power source (Ackermann and Söder, 2000). In the early 1970s, with the first oil price shock, the interest in the power of the wind re-merged. This time, however, the main focus was on wind power providing electrical energy instead of mechanical energy.

  • Globalization in the Wind Energy Industry: Contribution and Economic Impact of European Companies
    Renewable Energy 134 (2019) 612e628 Contents lists available at ScienceDirect Renewable Energy journal homepage: www.elsevier.com/locate/renene Globalization in the wind energy industry: contribution and economic impact of European companies Roberto Lacal-Arantegui European Commission, Joint Research Centre, Westerduinweg 3, Petten, 1755 LE, the Netherlands article info abstract Article history: This paper explores the globalization of the wind energy industry with a focus on the contribution by Received 5 October 2017 European companies and their economic impact in the global wind energy sector. Received in revised form The global wind energy industry is nowadays a tale of two worlds, China and the rest of the world. In 23 August 2018 the last five years, China installed between 37 and 48% of the annual world market, and it is all but closed Accepted 22 October 2018 to foreign companies. Consequently, Chinese manufacturers captured between 38 and 47% of the world Available online 1 November 2018 market whereas European reached between 41 and 50%. European manufacturers led in the rest of the world, serving between 73 and 82% of that market. They localise production and supply chain in the main Keywords: fi Globalization markets (e.g. India, Brazil, US) or in countries where producing for export is cost-ef cient (e.g. China, Wind industry Mexico). Turbine manufacturers enter new markets through joint ventures, technology licensing, Wind turbine manufacturers establishing wind farm developing subsidiaries, facilitating access to finance, or by acquiring a local Developers company. Wind energy sector Manufacturers help improve the capability of their suppliers and take them to serve new markets.
