|Abstract: ||Energy needs in the UK are currently met primarily through the use of finite resources, such as
oil, coal and gas. The use of these fuels has led to an increase in greenhouse gas emissions.
There is a need for a more localised and sustainable energy source to meet the demands of our
cities. Renewable energy is now being considered as a realistic contributor to both our energy
and environmental problems.
The contribution of small – scale distributed power generation from renewable sources to the
Scottish energy mix is examined. The daily potential energy available from wind and solar
resources will be modelled using spectral techniques such as Wavelets and Fourier analysis.
From this, synthetic time series of the energy available will be created based on the
characteristics of real life data. Along with this, a simple model for both the electricity and
heating energy consumption of a typical domestic building is proposed. This allows for the
approximation of daily domestic consumption values from monthly average energy values.
The potential energy available is then compared with the estimated domestic energy
consumption. The loads best suited for, and met by PV generating systems and wind systems
will also be assessed, along with the proportion of time that the domestic demand is met or
exceeded. This work will be backed up with realistic examples from building integrated
renewable systems based on typical data for Aberdeen. All this would allow for a potential
statistical relationship between energy supply and demand to be developed in the future.
The results of the analysis allowed for the estimation of the potential wind and PV system sizes
required to match either the typical summer or winter domestic demand. From these sizes, it
was concluded that a combination of a 5m2 PV system and a 1.5kW wind turbine was required
to match the typical domestic base load. Widespread implementation of these combined
systems, on suitable dwellings, could provide a 16% contribution to the Scottish domestic
