23 Priority Action Plan 12: IEC Objects / DNP3 Mapping Description: Developing an overall strategy whereby systems and components based on DNP communications can appropriately integrate with IEC based communications Perspective: DNP3 is the de facto communication protocol used at the distribution and transmission level; however, DNP3 does not possess all of the desirable attributes for use in the Smart Grid. A means must be found to enable transport of Smart Grid management functions over these legacy DNP3 networks. Associated SDOs: IEEE, IEC EPRI Lead: Joe Hughes Associated EPRI Programs: IntelliGrid 45 Priority Action Plan 12: IEC Objects / DNP3 Mapping Task Description Completion Date 1: Define Use Cases : Identify to what extent DNP XML supports the use cases and what the gaps are 3: Identify how SCL can make the external reference : Gap Analysis: Verify how SCL could support all use cases : Define rules for associating DNP XML and SCL in supporting use cases 6: Create Example DNP XML file mappings : Develop Guidelines for use of and DNP integration strategies 46

Associated SDOs: IEEE, IEC, Multispeak EPRI Lead: John Simmins Associated EPRI Programs: IntelliGrid 49 Priority Action Plan 14: Transmission and Distribution Power Systems Model Mapping This PAP is being combined with PAP 8 - Common Information Model for Distribution Grid Management 50

26 Priority Action Plan 15: Harmonize Power Line Carrier (PLC) Standards for Appliance Communications in the Home Description: There are multiple standards being developed for power line communications, but none are interoperable. This work will harmonize these different standards to enable the development of an profile that will result in interoperable products for home appliance applications. Perspective: Powerline Carrier (PLC) technology is suitable for Home Area Networks, some access applications (i.e. Advanced Metering Infrastructure), and has been selected by the Society of Automotive Engineers (SAE) for communicating with PH/EVs. Associated SDOs: IEEE, AHAM, CEPCA, HD-PLC Alliance, HomeGrid Forum, HomePlug Powerline Alliance, Universal Powerline Association, U-SNAP Alliance EPRI Lead: John Simmins Associated EPRI Programs: IntelliGrid 51 Priority Action Plan 15: Harmonize Power Line Carrier (PLC) Standards for Appliance Communications in the Home Task Description 1: Create a list of existing PLC technologies and revise them according to home appliances requirements 2: Create a list of existing coexistence mechanisms and revise them according to home appliances requirements 3: Harmonize coexistence standards if multiple candidates are found Date March 15th, 2010 March 15th, 2010 May 1st, 2010 This PAP has just recently been formed 52

27 Priority Action Plan 16: Wind Plant Communications NEW Description: Gather use cases and requirements from wind industry stakeholders with a focus on those requirements associated with integrating bulk wind assets into wind plant operation and utility command and control systems Perspective: While an international standard for wind power plant communications interoperability exists, few if any developers or utilities have implemented it in the US. Given that 1.5 billion dollars in ARRA funds have been awarded to wind plant projects, it is critical to accelerate the adoption of this standard to ensure those funds do not end up going to systems that are not interoperable which eventually results in stranded assets and less market competition.
