Under the current deregulation of electric utility industry, power system planning has become more complex. System planners are required to study how to use the available resources to meet customer's demand economically with an acceptable reliability and quality. The integrated resource planning is emerged as one of the effective approach for this problem recently and the approach has been expanded to include the value of reliability, that is, power interruption cost.
This paper is aimed to develop a flexible decision method to select a favorable plan among various transmission system expansion alternatives, not only from power supplier's view point, but also from customer's perspective including cost of interruption.
Bellman-Zadeh's maximizing decision using fuzzy decision set is applied as an flexible decision method which is able to reflect the planner's intensions. Numerical examples are shown to ascertain the effectiveness of the proposed method.
