In order to keep power supply reliability at a certain level, electric power utilities have a certain amount of reserved capacity. When no generator outage or no unexpected large power demand occurs, however, the reserved capacity is regarded as surplus facility. To reduce the reserved capacity, some margin is reserved in tie lines between utilities. This margin is called Capacity Benefit Margin (CBM). In this study, a method of calculating optimal CBM in tie line under deregulated environment is described and two kind of optimal CBM are proposed. As a result, it is shown how the deregulation affects the optimal CBM by using numerical simulation for IEE Japan West 30 test system.
