Abstract
The authors have proposed Flexible, Reliable and Intelligent ENergy Delivery System (called “FRIENDS”), which is a new concept for future power distribution systems. Also, “Micro grid” which is the similar concept to FRIENDS has been developed. In Micro grid, on independent distribution system can be constituted by a number of distributed generators. In this paper, FRIENDS, Micro grid and conventional distribution systems are compared quantitatively in supply reliability and system cost through time sequential Monte Carlo simulations. In addition, for cost evaluation, interruption costs are included to show risk incurred by unsupplied energy. Finally, authors search for preferable form with install and operation of distributed generators and network composition according to social cost including interruption cost and system cost.
