In recent years, there has been a possibility to become lower reliability in power supply system due to the competitive environment. Also, from demand side viewpoint, customer's preference of service reliability has been widely diverse. Reliability differentiated power supply system is one of the most effective solutions to cope with the above problems. This paper presents an integrated resource planning (IRP) model for evaluating the benefit of reliability differentiated power supply service from the social point of view. The proposed model consists of demand side and supply side sub-models. In the former sub-model, all customers are divided into some groups that are differentiated in supply reliability of electric power. The latter sub-model determines a best mix of generating units based on minimizing the social cost. The numerical examples illustrate the influences of the reliability differentiated power supply service on the generation mix and social cost.
