In power distribution systems it is extremely important to achieve rapid restoration of customer supply and speedy return to normal operating conditions following a system equipment fault or system abnormality. This paper extends existing techniques by describing the modeling and evaluating techniques that permit an efficient and practical probabilistic assessment of service restoration in distribution systems. These techniques recognize practical operating features of distribution systems and present to the system operator the most appropriate switching operations to be executed, in a classified order, together with all the associated information. A set of five probabilistic indices is also obtained which quantifies the impact of component reliability parameters and system operational practices on the restoration capability of distribution systems. Finally, the analysis of a typical 150kV/20kV system based on a real Greek distribution system is included.
