Abstract

Scientific evidence now shows a strong correlation between excessive greenhouse gas emissions and climate change. This has seen an increase in the average global air and sea temperature, which in turn is responsible for an increase in ocean levels and extreme weather events. The excessive greenhouse gas emissions are caused by human activities such as the burning of fossil fuels, agriculture, land use and forestry. Greenhouse gases are dominated by carbon dioxide which is largely generated by the energy sector. Carbon dioxide is a by-product of energy harvesting from fossil fuels, so to reduce emissions a carbon neutral source must be used. Small scale renewable energy systems have the advantages of being carbon neutral, are not depleted and are able to withstand power outages cause by extreme weather events. Small scale renewable energy systems come with the disadvantages of intermittency in power supply and a large financial cost. This thesis investigates the reduction of these disadvantages in order to increase small scale renewable energy usage in New Zealand. The research will analyse control algorithms for a localised power structure called a ânanogridâ, which will balance power consumption and production to decrease the effects of intermittency. It will also examine interconnecting multiple nanogrids to form a network which will further reduce intermittency and pursue financial reimbursement.
