Abstract

COLLABORATIVE PROPOSALS ECCS-0853402 and 0853403 The objective of this research is to investigate fundamental aerodynamic and power electronic issues of residential wind-power systems based on rooftop wind panels with horizontal rotors. The approach is airflow simulations and wind-tunnel experiments. Analysis of wind interactions within individual components of the panel and between the panel and the roof will be performed. Various configurations of these structures will be studied and conditions for maximum energy extraction from the wind will be determined. The intellectual merit of the project lies in the focus on fundamental aspects of residential wind-power systems, the barriers accounting for their meager popularity, and aerodynamic phenomena in horizontal sets of wind-turbine rotors. The research will: (a) advance the knowledge of aerodynamic properties of rooftop wind panels, (b) develop new designs of those panels, (c) determine the best schemes of power electronic interfaces for low-power wind-energy systems, and (e) produce new simulation models for future research endeavors. The broader impacts of the project include increased extent of wind energy in residential systems, mitigation of the acoustic and electromagnetic noise, and the resultant growth of renewable energy sources in households and small businesses. The project will thus impact the national renewable energy infrastructure, whose development is a vital part of the US energy policy. The project will strengthen research resources of the involved universities, including enhanced skills of graduate students, whose recruitment will focus on underrepresented groups. Results of the project will be disseminated in recognized journals, professional meetings, seminars, and public presentations.
