Mathematical modelling of BIPV-micro wind system: production, storage and usages

Clarke, Peter

Abstract

This thesis deals with the following aspects of renewable energy technology; solar energy modelling within the urban environment, performance of building integrated renewables including solar photovoltaics and micro wind technology. The development of hydrogen technology and electric zero emission transport is also reviewed.
Incident solar irradiation models have been developed to accurately incorporate the effects of shading, in order to enable the detailed simulation and estimation of solar energy systems within the urban environment. Both the Integrated Slope Radiation Model (ISRM) and the Sky Radiance Distribution Model (SRDM) have been developed to use readily available horizontal sub-hourly or hourly solar global and diffuse irradiation data. Shading parameters caused by the surroundings, such as building and trees, can be incorporated into the models. A software package based on these models has been developed to
allow the design and simulation of solar energy systems.
Horizontal solar global irradiation data is readily available around the world. However, diffuse irradiation data is available to a lesser extent. To resolve this problem and enable the above mentioned incident solar irradiation models to be used throughout the world a simple regression set was developed between the diffuse ratio, k, and clearness index, kt, to enable the estimation of horizontal diffuse irradiation from its horizontal global counterpart.
A review of building integrated renewable technology has been carried out. This includes the review of the performance of Edinburgh Napier University photovoltaic facade which has been in operation for over three years. Building mounted micro turbine technology is also reviewed. Performance analysis of three micro wind turbines installed on the rooftop of Edinburgh Napier University was undertaken, along with an analysis of the available wind regime observed at roof level. A software package was developed to aid the monitoring and analysis of both micro wind turbines and their observed wind regime.
Hydrogen technology is reviewed as part of the development of Napier Hydrogen Research Facility, enabling the demonstration of hydrogen generation, storage and use from renewables.
Finally, an analysis and comparison of a zero emission electric scooter with a conventional petrol car for use as urban transport was carried out. A driving cycle analysis was also undertaken to determine the environmental impact of both vehicles.
