Effects of renewable distributed generation (RDG) on voltage dip mitigation in microgrids

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 been an increase in the number of integrated RDG to the grid and also within the microgrids in other to support the power needed by the load during crisis. Current literature highlights voltage dips to be a serious problem, which has serious cost implication whenever they occur. One of the corrective methods has been mitigation through renewable distribution generation. This paper demonstrates how renewable distributed generation can be used to mitigate voltage dip as a result of faults from both the external grid and within the microgrid.
