Development of Reliability Indices for Electric Distribution Network in Egypt

Eman Ahmed, Sherein Abdualla, Kamelia Youssef, Hatem Waheed


Reliability indices (RIs) are the elemental benchmark used by Egyptian Electricity Holding Company (EEHC), and the Electric Utility and Consumer Protection Regulatory Agency (Egypt ERA) to evaluate the continuity and compliance of supply, which surpasses the customer's requirements and satisfaction. 

The power system is very complex, mixing huge different types of generating resources and clusters to supply electric power through transmission and distribution system to a number of customers with varying requirements.

The main function of electric system is to supply customers with electric energy that has an acceptable degree of reliability and quality. The power system continuity of supply level is controlled through system indices. The most widely used reliability indices are SAIFI, SAIDI and CAIDI (IEEE std. 1366-2000).

Historical electrical indices, reliability indices threshold and satisfaction index are used as guide for electric network performance, which measure the adequate and secure power supply.

The paper presents the reliability indices, relation between indices and satisfaction area to highlight the appropriate guideline values for electric systems, also presents the development of indices since 2011 to now for distribution network in Egypt.
