Reliability evaluation of distribution systems with mobile. system components that make up an electric distribution system. This connection makes apparent the fact that overall system design, including construction practices, impacts fundamental reliability. From substation and distribution design to fusing schemes, various physical factors of system design impact system reliability., There is no generally available implementation or methodology that will permit distribution system planners to predict distribution system reliability. Not only is a usable methodology absent, but there is no general framework available for reliability-based decision making in the distribution system..

While [6] described a way to evaluate the impact of partial automation on system reliability, it does not present an economic evaluation of shortened storm response. The weather environment can severely impact the performance of an overhead distribution system and an electric utility's operational ability. The likelihood of system failure increases due to enhanced line failure rates during bad weather periods. Reliability appraisals without incorporating weather conditions can be quite optimistic and affect planning and design decisions.
