Abstract
An exemplary method and system are disclosed for coordinated transfer of control in a substation system having IED or logical devices/servers using GOOSE messages with preconfigured data models with logical nodes containing one or more data objects including private data objects (DO) connected in the substation communication network. The method for transfer of control can be illustrated for hot-standby device management and for other applications such as logical isolation of merging unit in a substation and load sharing between IEDs. The method can be used for devices that do not have MMS stack.
