Variable geometry wind turbine for performance enhancement, improved survivability and reduced cost of energy

Abstract

The conceptual design and proof‐of‐concept testing of a furling vertical axis wind turbine, suited to large‐scale offshore deployment, is described. Through the implementation of variable geometry capabilities, extreme storm loads can be reduced, and unsteady flow‐related fatigue loads can be minimized thereby reducing capital (structural) and maintenance costs. Moreover, annual power generation can be optimized in real‐time to account for unsteady wind effects related to weather and siting thus improving efficiency and annual power generation.

A novel wake energy reuse method to optimize the layout for Savonius-type vertical axis wind turbines

“…3(a). According to previous studies [6,7,15], a simplified two-dimensional model can be used to describe the wind turbine, as shown in Fig. 3(b).…”

“…• Simple construction and low noise emission [7,8] These advantages make S-VAWTs suitable for small and medium-sized distributed power generation.…”

Ontario’s Experience of Wind Energy Development as Seen through the Lens of Human Health and Environmental Justice

“…This is currently about 40% of Canada’s total installed capacity and nearly 10% of Ontario’s energy mix [ 1 ]. In contrast to the aforementioned merits, the technology faces some challenges within certain deployment contexts, a few of which include grid integration and variability [ 2 , 3 ] and concerns over wildlife [ 4 ].. Despite the promises of the GEA and WED to deliver clean energy and green jobs, development is fraught with conflict across technical, economic, social and, our focus here, health issues.…”
