The advent of power quality sensitive equipment has made the provision of good power quality a real challenge across the globe. With the increasing usage of sophisticated sensitive electronic equipment in industrial, residential and commercial sectors, it is important to protect them from any power quality disturbance in order to avoid equipment damage and malfunction leading to financial loss for...
The paper analyses the nature of voltage dip in electrical networks integrated with wind energy conversion systems (WECSs) with three different types of generators, viz., permanent magnet synchronous generator (PMSG), doubly-fed induction generator (DFIG) and the fixed speed induction generator (FSIG). The test network along with the wind generators and loads is modeled in DIGSILENT Power Factory...
Voltage dip has been identified as one of the common types of power quality disturbance in electrical power networks and drew a lot of attention in voltage quality research presently. It is regarded as the most costly power quality problem. It can be caused by starting electrical motor, switching of generators or bulk loads, transformer energizing and short circuits in the power networks. In recent...
Power and energy industry infrastructure dictates the economic growth in any country. The increased use of sophisticated sensitive ICT and semiconductor devices at homes and offices has also led to monitoring of voltage profile and has increased the challenges for utility and industry to focus on power quality related to voltage dips and swells. Industries where a delicate industrial processes demand...
Currently, there has been a significant interest in deployment of renewable and low carbon energy sources in the form of microgrids for local energy generation. Microgrids operate in two modes — stand-alone and grid-connected. This poses a problem in microgrid protection settings in a sense that the fault current magnitude in a microgrid reduces drastically during its transition from grid-connected...
South Africa, with steep population and economic growth is suffering from energy deficit, like many other developing countries. The demand is becoming greater than the available generation in the country. Hence, much research is on in South Africa regarding deployment of alternative energy sources such as solar PV and wind plants for local energy generation to supply remote and off-grid areas. Currently,...
In the year 2007, South Africa experienced high demands of electricity power than that could have been generated. Due to greater demand than the generation, the country experienced planned and unplanned load shedding. Hence the commercial operations, industrialization country's economy and mostly people's life styles were highly affected. The unplanned load growth, indiscriminate integration of distributed...
Many countries are accepting the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) in other to reduce the emission of carbon dioxide and other greenhouse gases. Renewable distributed generation (RDG) has become one of the most effective ways to reach this goal. It has been recognized as an alternative way of generating clean energy around the globe today. There has...
In the current power and energy scenario, distributed generation (DG) has generated a lot of interest across the globe due to the growing concerns about gradual depletion of fossil fuels, steep load growth, environmental pollution and global warming caused by greenhouse gas emissions. Renewable DGs such as wind generators and solar photovoltaic are well-recognized now-a-days as sources of clean energy...
Voltage dip has been a serious problem in electricity networks. It accounts for the disruption of both the performance and operation of sensitive electrical and electronic equipments, which has reduced the efficiency and the productivity of power consumers across the globe. In order to secure quality power supply this problem needs attention for a sustainable solution. In the field of electrical power...
