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 ...

Wind power prefeasibility study for agricultural applications in Kerman, Iran: a case study
In the present paper, wind characteristics have been analysed for three agricultural sectors in Kerman (30°15'N,56°58'E), Iran. Wind data collected from three synoptic stations for the period of July 2006 to June 2011 at the height of 40 m has been used to study the monthly and annual wind energy potential. Two statistical methods (Meteorological and Weibull) have been applied to ...

Danish and Dutch wind energy policy 1970–2000: lessons for the future
Both in the Netherlands and in Denmark, policies to develop a wind turbine industry and to install a large wind turbine capacity were started in the 1970s. However, the outcomes of these policies were very different. A flourishing wind turbine industry developed in Denmark, whereas in the Netherlands, a few companies started building wind turbines in the 1980s and 1990s, but presently no wind ...

US wind turbine suppliers predict extended repowering wave
Turbine and tower advancements could sustain repowering activity into the next decade, outweighing the impact of falling tax credits, leading suppliers told New Energy Update. U.S. demand for wind repowering is surging as operators rush to maximize asset returns amid dwindling production tax credits (PTCs). Leading U.S. turbine supplier GE Renewable Energy has repowered 4 GW of U.S. wind ...

Global wind speeds bounce back to hike output; New Jersey raises offshore target to 7.5 GW
Global onshore wind speeds are rising, new study finds Global onshore wind speeds have risen since 2010, after decades of decline, boosting potential wind energy by around 17% between 2010 and 2017, according to a new academic study published in Nature. Rising wind speeds have increased U.S. wind turbine capacity factors by around 2.5% since 2010, representing half the gains in capacity ...

As Europe extends turbine lifespans, data becomes crucial
Ageing wind assets, growing corporate demand and limited appetite for full repowering are favoring lifetime extension projects, increasing the importance of performance analysis. European lifetime extension (LTE) activity is set to hike in the coming years as feed-in tariffs expire and wind operators seek to maximize revenues from ageing assets. Around 4 GW/year of European wind turbine ...

Adoption hurdles and challenges with small wind turbines
Adoption Hurdles and Challenges with Small Wind Turbines Wind energy is very promising. It can be harvested without any costs, and like solar panels, wind turbines are environmentally-friendly. However, such machines are not living up to their potential. Some users have reported low efficiency rates, unpredictable performance and costly adoption barriers. This article dives into the challenges ...

US wind O&M thrust creates new roles, supplier networks
U.S. wind operators will invest in repowering, digital tools and remote technologies in the coming decade, supported by deeper service and spares networks, analysts and suppliers told New Energy Update. The phasing out of the U.S. federal production tax credit (PTC) is set to profoundly impact wind industry spending and employment trends. The 10-year PTC is set at $23/MWh for projects ...

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 ...

International investment in the South African renewable energy market
A renewable energy market of extraordinary growth In just four years, South Africa has gone from being a coal-dependent economy to a prime destination for renewable energy investment. Largely propelled by the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) which commenced in August 2011, the scheme has procured 79 projects with a capacity of 5,243 MW under the four ...
