Abstract:
Electric power system may suffer from unreliability condition due to scheduled and unscheduled outage of the system components such as transmission lines, generators and transformers. Therefore the system will not be able to meet the demands. This conditions cause massive loss to the economy.Thus, increase cost. Reliability in power system is measurement of the ability of power system to provide the electric power requirements of customer at all times continuously and economically. In this project the reliability analysis is done to Sudanese National Grid (SNG) as case study to determine and analyze the effect of reliability indices on all bus-bars in the system by consideringExpected Interruption Cost (ECOST), and Effective Expected Energy Not Supplied (EENS) as reliability indicators.
The convenient results obtained from reliability analysis to SNG done by the aids of ETAP simulation software, all buses evaluated based on reliability and classified according to how they will be affected by the indices of reliability and more affected bus will be identifiedthis is help in overcome the unreliability conditions. From result obtained it found that Sudanese National Grid unreliable
