economic evaluation. In [5] the authors described a model based distribution control scheme which is configurable and hierarchical, again without an economic evaluation. 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.
