Single phase AC traction systems pose unique challenges to power utilities at interface points of connection on the power delivery network. Traction systems are usually supplied from dedicated utility networks in order to minimise the negative effects that traction loads have on conventional three phase loads, particularly in instances where customer equipment may be sensitive to the quality of supply...
Photovoltaic (PV) power system provides an effective method of power generation; this is particularly relevant to developing countries, where the demographics show that the majority of the populations are settled in remote and isolated settlements. The challenge facing these settlements is that they generally have no access to the electric grid and often lack basic infrastructure. Technological developments...
Photovoltaic systems alongside energy storage systems are a recognized distributed generation (DG) technology deployed in stand-alone and grid connected system for urban and rural applications. Installing DG at or near a customer load can eliminate the need to upgrade existing transmission/distribution networks to handle the extra power requirement. Since these distributed energy systems are inertia-less...
Power sector deregulation is a global phenomena but driven locally by a mix of complex forces peculiar to each country. Using a case-study example, this paper evaluates distribution (embedded) generation as an option for developing economies to ensure system stability and improve reliability. A methodology for evaluating distributed generation (DG) services is proposed and a framework for integrating...
Africa has 15% of the world's land area, 13% of the world's population, uses approximately 3% of the world's electricity but accounts for only 2% of the global industrial capacity. With an installed generation capacity of approximately 105000 MW, Africa has a relatively small power infrastructure in comparison with its geographic size and population. This paper sets out to achieve the following: identify...
Asset management is a concept that has been used in both the private and public sectors with a vast number of interpretations. In the context of an electricity distribution utility, asset management can be defined as a systematic process of, cost-effectively, operating, maintaining and upgrading of electrical assets by combining engineering practices and economic analysis with sound business practice...
