Abstract
The main purpose of this paper is to study the implementation of load shedding under the condition of IEC61850 (Communication Networks and Systems in Substations) communication exchange in the power system. The strategy of load shedding with IEC61850 GOOSE (Generic Object Oriented Substation Event) message relies on fast transmission of the signal to shed unstable regions for maintaining system safety. The current strategy for load shedding in the substation is to use hardwire and dispatch solutions to implement related applications of load shedding. For integrating protective relays in substations, IEC61850 GOOSE schemes can customize both a ring and a star construct based on TCP/IP Ethernet to have flexible dispatch of smart grid solutions. The functions of relay integrated with the GOOSE message play important roles to implement peer to peer communication to accomplish the load shedding strategy.
