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 ...

Long-term stabilisation of grid connected wind farms with FACTS controllers
The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view of the environmental constraints, grid connected wind turbines are promising in increasing system reliability. This paper presents the impact of FACTS controllers on the long-term dynamic stability of power systems connected with wind farms based on ...

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. ...

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 ...

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 ...

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 ...
