With the increasing use of technologies and automation in different sides of modern life, the outage of electricity became a big issue that widely affects the daily life of most sectors like industrial, economical or even entertaining sector. So it became so necessary to achieve a high-reliability electrical system to insure the continuation of electricity supply to the end consumer. Consequently, in this research, we are studying a new method of service restoration using genetic algorithms to increase the reliability of distribution systems and improving its performance. The research includes a brief aver view of electrical systems reliability and the basics of Genetic Algorithms and the use of these techniques in dispatching centers. In addition we have designed a program in "MATLAB" environment to apply the service restoration technique using genetic algorithms, and the program has been tested on a case study with the relative results shown .
