FRIENDS: forwarding to future power delivery system

In this paper, many issues on a new type of power delivery system named FRIENDS (flexible, reliable and intelligent electrical energy delivery system) are discussed. FRIENDS is one of most promising future power delivery systems under deregulated circumstances. The purpose of FRIENDS is to develop a desirable structure for future power delivery systems where distributed generators and distributed energy storage systems are allocated near the demand side, and to develop reliable and energy conservation oriented operating strategies of the power systems. The future power delivery system will be more and more consumer friendly and will be a more and more essential part of the total energy delivery system.
