  • International energy technology collaboration: wind power integration into electricity systems

    A rapid growth of wind power since the 1990s has led to notable market shares in some electricity markets. This growth is concentrated in a few countries with effective Research, Development and Demonstration (RD&D) programmes and with policies that support its diffusion into the market place. The speed and depth of its penetration in these electricity markets have amplified the need to address ...

  • Zig–zag transformer for neutral current compensation in an isolated wind energy system

    This paper presents a voltage and frequency controller with neutral current compensation in a stand alone wind energy conversion system (WECS) employing an asynchronous generator. The proposed controller consists of a three leg insulated gate bipolar junction transistor (IGBT)–based voltage source converter and a battery energy storage system (BESS) at its DC bus. The neutral terminal for the ...

  • Wind energy and system security – the grid connection moratorium in Ireland

    This examines the interaction between technical challenges and policy choices that are made regarding wind power, and uses the grid connection moratorium in Ireland as a case study. While total installed wind capacity in Ireland is low compared with Germany, Spain and Denmark, wind power penetration is higher in the Irish system than in either the British, UCTE or NORDEL systems. In December 2003 ...

  • Wind energy in Italy: regulatory and technical aspects

    Italy has carried out the deregulation of the electricity sector. The EU 'Renewable Directive' gave Italy a very ambitious burden sharing: by 2010, 25% of the demand will be faced by renewable energy against a 1997 baseline of 16%. To sustain such development, the producers/importers have a yearly obligation to inject into the system 'green production': in 2002 by 2% increasing to 3.05% by 2006 ...

  • Prospect of offshore wind energy development in Japan

    In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

  • Dispatching of wind farms using battery energy storage

    In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...

  • Environmental impacts of integrating wind energy systems and supplemental energy generation and storage systems

    Wind energy systems offer a promising alternative energy source due to the environmental, economic, and social benefits and, as a result, have garnered support for development and implementation. One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a ...

  • Aiming High Rewarding Ambition in Wind Energy - Report

    EXECUTIVE SUMMARY With 392 GW installed, wind energy can be the single largest source of power generation in the EU by 2030 ahead of coal and gas. Wind energy already plays a significant role in the European power sector. In 2014, the wind industry installed 11,791 MW in the EU - more than gas and coal combined. Today wind energy can meet 10.2% of Europe’s electricity demand ...

  • Denmark generates 140% of energy from wind power

    On July 09, 2015, Denmark reached a renewable energy milestone by becoming the first country to generate 140% of its energy needs with wind power. According to The Guardian, the surplus energy was redistributed to neighboring Germany, Norway, and Sweden. The ...

  • Trading wind in a hydro-dominated power pool system

    In 1996, the Danish government launched an ambitious energy plan, Energy 21, describing a way to develop the energy sector in a more sustainable direction. Wind power plays an important role in the plan, and as a consequence there will be a very high penetration of wind energy in the electricity sector. This will put in focus issues of fitting a variable energy source into a stable supply system. ...

  • On methodology for modelling wind power impact on power systems

    There is a continuous discussion going on concerning the integration cost of wind power. The integration cost can, for example, be defined as the extra costs in the rest of the system when wind power is introduced, compared with the situation without wind power. The result of the studies depends on both parameters and the method used. The aim of this paper is to structure the methods in order to ...

  • On limits for wind power generation

    The amount of wind power in the world increases fast. The background for this development is improved technology, decreased costs for the units and an increased concern of the environmental problems of competing technologies such as fossil fuels. For the future, it is now interesting to evaluate where the limits are for wind power generation, and which points are crucial. Since there is no power ...

  • Experience curves for wind power

    The objective of this study was to improve the understanding of the use of different experience curves in energy analysis. The study was based on the application of experience curves to wind power systems, but the approach is generic and can be used in other energy technologies. In the study, experience curves for wind power were developed, and it has been demonstrated that different types of ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Optimal scheduling and operation of hybrid biomass/wind/PV energy system for rural areas

    In this paper, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV) and battery, is proposed. The sources are operated to deliver energy at optimum efficiency. An optimisation model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • The Future Cost of Wind Power

    Chapter 1 The economics of wind power Wind power is capital intensive with most of the investment required upfront. The largest capital cost component is the turbine itself which can account for between 40% and 80% of the total capital cost of an onshore wind installation. Costs offshore are higher because of the more expensive operating environment and the greater difficulty establishing ...


  • The VGOT Darrieus wind turbine

    We present the actual state of development of a non-conventional new vertical-axis wind turbine. The concepts introduced here involve the constructive aspects of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade slides over rails mounted on a wagon instead of rotating around a central vertical axis. Each wagon contains its own ...
