  7. Abstract:
  8. In a deregulated environment of power distribution industry, a comprehensive economic evaluation for the implementation of distribution automation systems is inevitable. It plays a key role in enabling distribution companies to achieve their business goals. In this thesis, a dynamic economic evaluation is presented to provide a comprehensive perception of automation intensity level and investment plan, for maximizing the utility profit and obtaining the desired payback period. Using the presented methodology in this thesis and system dynamics approach, it is efficiently possible to deal with variation of the economic parameters such as the interest rate, inflation rate, energy supply cost, load growth, etc. Based on the resulted dynamic modeling, economic short-run and long-run impacts of SCADA systems are evaluated from utility point of view, and also from customers’ point of view. The reduced energy revenue, capital cost, labor cost, energy loss and supply costs, revenue due to electric service quality, performance-based penalty, and so the total cost, total revenue, profit, and benefit/cost ratio have been illustrated during a particular planning horizon which is taken 10 years in the case studies. The distribution network topology, reconfiguration capabilities, customer types, and customer outage characteristics are taken into account. Furthermore, a practical pricing strategy is suggested for reliable electric service, depending on the underlying market structure of electricity.
