Reliability Enhancement of Smart Distribution Network Using Reconfiguration

Abstract

Electric power should deliver a predicable per condition for the technological, economic, and political development of any countries and it is vital for each individual. Power outage is series problem in Ethiopia at the hole of distribution network. This is due to frequent interruptions and much time service restoration. That is why most customers of Ethiopia have their day-to-day activities highly affected and they are strongly complaining to Ethiopia electric utility daily. But this power outage affected customer cost and the Ethiopian utility. In most developing countries including Ethiopia, distribution systems have received considerably less of the attention to reliability modeling and evaluation than have generating and transmitting systems. Life is directly or indirectly dependent on electric power so a utility should deliver reliable power every day for 24 hours and each year for 8,760 hours to satisfy human needs and to perform their works as much as possible with less economy.

The impact of selected variants of remote control on power supply reliability indexes of distribution networks

“…The complexity of these networks lies in the fact that one line may supply the large number of medium-voltage/low-voltage transformer stations, which makes it difficult to quickly locate a failure. Effective and quick location of network interferences with the use of remote-controlled switching automation allows to improve the functioning of energy distribution systems [17,18]. Broadly defined telemechanization of switching processes contributes to effective reduction of duration of location of damages and change of network configuration, which effectively improves functioning of a medium-voltage network, causing minimization of the number of disconnected consumers [7,16].…”
