Abstract:
The percentage of renewable energy within the global electric power generation portfolio is expected to increase rapidly over the next few decades due to increasing concerns about climate change, fossil fuel costs, and energy security. Solar thermal energy, also known as concentrating solar power (CSP), is emerging as an important solution to new demands for clean, renewable electricity generation. Dish-Stirling (DS) technology, a form of CSP, is a relatively new player in the renewable energy market, although research in the technology has been ongoing now for nearly thirty years. The firs

Abstract:
Hybrid renewable energy systems (HRES) have proven to be a more stable and feasible source of energy than heir single source counterparts. The benefit of HRES is their ability to balance the stochastic behavior of wind and solar production. As result of this, they have been used as stand-alone systems with great success. Optimization studies in the field have shown optimum sizing of the components in the system to be a key element in order to increase feasibility. This paper focuses on the HRES impact on internal grid design and cost. The goal of the thesis is to create a mathematical function

Solar power tower (SPT) plants with thermal energy storage (TES) provide great opportunities on the utility-scale; becoming a viable option for areas with moderate to high direct solar availability. The absence of commercial SPTs in Australia, together with the need to increase renewable energy capacity, raises the importance of proving it viable and beneficial.

Abstract:
Power electronic converters have become popular in the field of power transformation for renewable energy. Power electronics converters achieve high efficiency, and the price of their components is falling, thus making them even more beneficial for renewable energy applications. Those systems coupled to the grid need to withstand certain utility-defined circumstances which may occur during operation. Additionally the new net regulations for large generation plants specify that during specified severe grid disturbances the relatively delicate converters should stay connected supporting the syst

Abstract:
In grid-connected photovoltaic applications, a supply-frequency output transformer is normally used to isolate the inverter from the supply. This transformer is heavy, costly and adds to the overall power loss. However removal of the output transformer can result in unwanted DC components appearing in the inverter output current. Excessive DC current injection into the distribution network can affect distribution components as well as other loads connected to the network. There are various circuits which can be used to for grid connection without the use of an output transformer. These include

Abstract:
The integration of DG into utility networks has significantly increased over the past years primarily as a result of growing energy demand, coupled with the environmental impacts posed by conventional fossil fuel-based power generation. The prominent DG technologies which are capable of meeting bulk energy demands and are clean energy sources are wind and solar energy sources. The resources for solar and wind based DG are available in abundance in most geographical locations in South Africa and the rest of Africa.

Abstract:
The fast depletion of fossil fuel has increased the havoc and need of finding an alternative for the existing fossil fuel based energy industry. As a result, many renewable energy sources such as Solar, Wind, Geo Thermal, Bio mass, etc... are being looked in to. One of the major sources of renewable energy is our sun. There are two methods of tapping the energy from the sun. 1. Solar Thermal It involves using the sun’s heat directly in some processes or indirectly to produce electricity. 2. Photo Voltaic It involves using the light to produce electricity using Photo Voltaic cells. This report

Thesis (MScIng)--University of Stellenbosch, 2004.<br>ENGLISH ABSTRACT: One of the areas of the fluid dynamic design of solar chimney power plants that has not been investigated sufficiently is the collector-to-chimney transition section of a single turbine layout. The transition section contains the turbine inlet guide vanes (IGVs) that support the whole chimney and guide the flow entering the turbine. The primary objective of the study was to determine the dependence of the loss coefficient of the section on inlet guide vane stagger angle and collector roof height. Experiments were don

Abstract:
This research thesis covers the latest research on renewable energy globally and focuses on the solar panel and biofuels market. A full macroeconomic analysis is done on the Chinese Taipei, and this results in some parameters which then become the basis of this research. The macroeconomic parameters are then put into a tabular form and applied to India, Turkey and Australia to see how much weight the analysis can hold and if there is enough data per country on the macroeconomic parameters chosen. This research thesis conducts a shorter, custom version of a macroeconomic analysis on a South Afr
