System Restoration Navigator: A decision support tool for System Restoration

Abstract

Power system restoration is well recognized as an important task to reduce the duration of a disturbance that occures in power systems. The complex tasks of emergency recovery require advanced decision support tools to enhance the resilience and, utimately, self-healing capabilities for a smart grid. A piece of software entitled “System Restoration Navigator” (SRN) has been developed based on the Generic Restoration Milestones (GRMs) concept, with the support of EPRI during the last two years. This paper addresses the development and functionality of SRN. Firstly, the basic philosophy of GRMs is introduced. Secondly, the functionality of SRN and integration of SRN with EPRI Operator Training System (OTS) are demonstrated. Thirdly, the Power and Light (PALCO) system is used to illustrate the general restoration plan and concrete restoration actions under a blackout scenario. It is believed that the development of SRN and its integration with OTS is a major step towards the on-line decision-making for system restoration.
