PAP 14 Objectives Develop strategies to expand and integrate MultiSpeak, IEC 61850, IEC 61968, IEC 61970, IEEE PC (Time Tagging), IEEE PC (COMFEDE) and the future IEEE Common Settings file format for Smart Grid Applications.MultiSpeak Develop a summary of information required from the power system for various Smart Grid applications. Map that information with the already defined models from MultiSpeak, IEC 61970, IEC , and IEC MultiSpeak Coordinate with the SDOs to extend the existing models.
PAP 14 Objectives Continued Identify setting information that is required to perform an automatic verification of the power system configuration to prevent failures due to mis configurations. This information shall include both settings in the devices as well as parameters of the power network that need to be available for verification. – long-term issue (two-year effort) and is Use Case-based; step one: IEEE group work PSRC H5; Coordinate with the SDO to extend the existing standards as a result of defining next generation Smart Grid T&D functions.

Q UESTIONS TO BE ANSWERED BY THE ANALYSES OF POTENTIAL ISLANDING Is the load-generation imbalance manageable during the island situation? –Will DER separate due to frequency or voltage, or both – with or without load? –Will the weak tie be overloaded? –Is the load shedding sufficient, etc.? –Are the priorities of load shedding adequate? –How will the situation develop during prolong islanding? –What is the latency and the possible contribution of Demand Response and VVWO? –What is the risk (uncertainty) factor? What re-coordination of protection and RAS would be needed?
??? What is the expected cold-load pickup? What is the latency and possibilities of DER resynchronization? What should be the priorities of load restoration? The TBLM should contain information that is needed to answer these questions. Questions Continued
