In future power systems, the service interruption in the electric energy supply will be easily realized by using communication networks. In order to apply the new service widely, it is important to design a transparent pricing menu for all customers. When designing the pricing menu which consists of the price and the reliability indices, it is necessary to consider that both the customer composition and the reliability of the incoming power are different among the buses.
This paper evaluates the reliability differentiated supply system considering the local characteristics in power systems. The proposed method consists of three main parts. Every customer is assigned to either high reliability subset or standard reliability subset using the information of outage cost so that the total outage cost is minimized. Next, the authors determine the price ratio of high reliability menu (menu-H) to standard reliability menu (menu-L) for guiding every customer to the above assignment pattern. Further, in order to realize a consistent pricing in overall power systems, the authors propose a pricing policy that the prices of menu-L are same in every bus. Through numerical examples of a small network system, the authors investigate how the reliability differentiated pricing menu is affected bv the local characteristics in rxrwer systems.
