Wind energy today and in the 21st century
Wind energy is the most promising of the new renewable sources of energy. By the end of 1998, the global installed capacity of modern grid connected wind turbines was some 10,000 MW, and the growth rates of installations worldwide are 30%-40% annually. The cost of wind energy was reduced by 30% between 1991 and 1997 and the cost reduction is foreseen to continue. This article reviews the reasons ...

Solar farm for Mackies Ice Cream - Case Study
The Mackie family have been farming at Westertown farm since 1912 and Mackie’s of Scotland is now a well-known Scottish food brand. Mackie’s were formerly a milk retail company and in 1986 began making ice cream. They have an ambition to be the greenest company in the UK. In 2014/2015, Absolute successfully won a tender against SSE to install Scotland’s first solar farm. It was ...

Record 13bn euro invested in offshore wind in 2015: 3GW new capacity
Offshore wind investments in Europe doubled in 2015 to €13.3 billion in a record year for financing and grid-connected installations. A total of 3,019 MW in new offshore wind capacity came online in European waters in 2015, more than double what was connected to the grid in 2014. Europe's total offshore wind capacity is now 11,027 MW. A further 3,034 MW of capacity - spread across ten ...

A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator
This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

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 ...

Harmonic and interharmonic distortion analysis in the grid-connected wind electric generator
The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. Harmonic distortion is one of the most important phenomena which affect the grid performance. This paper provides an in-depth discussion on harmonic and interharmonic ...

Vector control of current regulated inverter connected to grid for wind energy applications
Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

Optimal control of matrix converter based WECS for performance and stability enhancement at low wind speeds
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal ...

A comparative study on the grid integrated wind energy conversion systems (WECS) using different generator models
A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. This paper presents comparative study on grid connected WECS having two different wind turbine generator systems (WTGS): model 1 [WTGS having doubly ...

Wind Surpasses Nuclear in China
Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. Before the March ...
