Abstract

This paper describes a new advanced security monitoring system for Energy Management System(EMS). In this paper, we propose a new concept called successional static monitoring. The successional static security monitoring system evaluates each snapshot which has different network state. It has been difficult for dynamic security monitoring to simulate all the restoration process, because actual restoration process includes change of network configuration and change of power supply, and all the restoration process can not be simulated successively. In order to realize this new concept, this system includes two simulators. One is Network Simulator that calculates load flow and frequency dynamic characteristic of each snapshot. The other is Dispatch Center Simulator that decides the various command to
control generators and searches for the restoration routes when a black out occurs. It includes the intelligent dispatcher model that emulates the various actions of human operators. Also this system calculates the running cost of generation that satisfies trade-off for various security index.
With these simulators, this system evaluates the restoration time and estimates restorable loads after contingent faults through the all restoration precess.
