Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...

In this study, the feasibility of using micro-wind turbines to power wireless sensors on a cable-stayed bridge is comprehensively investigated. To this end, the wind environment around a bridge onto which a turbine is installed is examined, as is the power consumption of a wireless sensor. Feasible alternators and rotors are then carefully selected to make an effective small wind generator (kno...

In the offshore renewable energy industry, it is extremely important to reduce the likelihood as well as the magnitude of potential risk events during system’s actual operation. Operational risks (either risk of system failures or environmental risks) may cause catastrophic damages to personnel or infrastructure and result in substantial costs in terms of lost production and emergency maintenan...

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.

David W. Keith holds the Canada Research Chair in Energy and the Environment in the departments of Chemical and Petroleum Engineering and Economics at the University of Calgary, where he works on climate-related energytechnology, science, and related public policy. His recent work has focused on the capture and storage of carbon dioxide and the economics and climatic impacts of large-scale wind...
