SGIP Strategic Projects & Deliverables Interoperability Implementation Experiences (IIE) List of implemented Smart Grid applications Identifying key standards implemented Interoperability Mapping Tool (IMT) Port, customize and operate an interactive, online tool Include SGIP’s CoS, plus work of the DEWGs and PAPs Business Impact of Standards Analysis Services Develop and apply a methodology to assess business impact Calculate benefits and costs of interoperability experiences Educational & Informational Services Based on the results derived from IIE and IMT programs Identify the most relevant “vectors of influence” Interoperability Implementation Experiences This program will create a process to learn from Smart Grid interoperability implementation experiences -- the new “Interoperability Implementation Experiences” (IIE) program. This program will develop a list of smart grid applications that have or are being implemented that make use of key standards (both existing and emerging) or interfaces between different standards. An emphasis will be placed on standards that are in SGIP’s Catalog of Standards. The SGIMC members will be used to prioritize the applications list. Standards Mapping Tool This program intends to port, customize and operate a smart grid interactive Interoperability Mapping Tool (IMT). SGIP plans to license GE’s smart grid mapping tool as the basic platform to ensure coverage of the entire Smart Grid value chain. We will then expand the tool’s existing nodal database to include the SGIP’s Catalog of Standards, work of the DEWGs and PAPs, and the “Interoperability Implementation Experiences” project deliverables/standardized templates.   Business Impact of Standards Analysis Services Future information service projects are planned to develop and apply a methodology to calculate the benefits and costs of SG interoperability for different interoperability experiences; then leverage or build upon a suitable existing methodology, if available. This analysis will be used to estimate the business impact of using standards that enable interoperability of devices and systems in the Smart Grid ecosystem. Educational & Informational Services Additional educational and information services are planned to be developed based on the results derived from the previous new programs (IIE and IMT). These will be designed to assist members in preparing stakeholder category and organization specific roadmaps to identify their most relevant “vectors of influence” within the Ecosystem. These services will enable member organizations to better plan projects and product deployments based on the speed, direction and impact of standards to drive interoperability.

White Paper: NISTIR 7628 User’s Guide Feb 2014 While NISTIR 7628 covers many significant cybersecurity topics, this User’s Guide is focused primarily on the application of NISTIR 7628 Volume 1 in the context of an organization’s cybersecurity risk management practices. The User’s Guide provides an end-to-end implementation guide for an organization’s Smart Grid cybersecurity activities, and references the Department of Energy (DOE) Electricity Subsector Cybersecurity Risk Management Process (RMP) to provide the cybersecurity risk management framework and organizational structure needed before system-specific controls identified in NISTIR 7628 can be applied. The User’s Guide was developed with significant involvement by utilities, and is designed specifically to aid utilities in choosing and applying appropriate cybersecurity guidance found in NISTIR 7628 Volume 1 to their Smart Grid systems.

Create DER architecture diagrams that are mapped to the European SGAM format, and cover the range of different configurations and DER management infrastructures. Develop categories of DER use cases based on the configuration of DER grid connections, DER roles in logical and/or islanded microgrids, the kind of authority for DER management, the range of communications capabilities, and the DER types and their functional capabilities. Describe the process for expanding the key use cases at each of the five hierarchical architecture levels to include all pertinent categories. These expanded use cases can then be used to identify information exchange gaps in international standards

Harmonization Requirements PAP21 Process Flow Business Case State our reason for being and success Use Cases Illustrate the applications space of the result Harmonization Requirements Derive requirements for the activity Hand off to SSO(s) ~Feb-Mar 2014 ~April-May 2014 ~June-July 2014 9/23/2018

Business Case Outline Executive Summary Having a more harmonized weather exchange model among the many current formats increases interoperability, improves data quality, and reduces the cost of acquisition of weather information which allows more resources to be devoted to innovative uses of weather. Who are we? The Smart Grid Interoperability Panel (SGIP) accelerates the implementation of interoperable smart grid devices and systems. The Challenge Detailed knowledge of weather – current, historical, and forecasted – can provide the basis for Smart Grid stakeholders to optimize current and future operations and to mitigate disruption and damage from adverse weather events. Why Harmonized Weather Standards Will Help In order to exploit weather data, it must first be acquired and analyzed. The process of data acquisition itself is purely overhead and does not provide any direct value. Value comes from analysis of weather data once obtained. What Will Drive This Forward Stakeholders in an open weather data ecosystem will thrive with harmonized and low-impedance availability of data for exchange 9/23/2018

PRIORITY ACTION PLANS

PAP-21: Weather Information Identify Use Cases (UCs) that illustrate the benefits of bi-directional weather data exchange Coordinate development of UCs with inputs from a wide range of industries Produce a set of information requirements designed to facilitate the harmonization of information models and exchange models Smart Grid Weather Standards There are multiple SSOs with standards development efforts related to weather information exchange: WXXM is a general standard weather information model that was initially developed for aviation and is now and international standard of the WMO. ASHRAE SCP201P is a building/facility information model standard focused on loads; it includes a weather model based on WXXM with minor extensions. IEC 61850 and IEC 61400-25 include weather information modes for data from towers at power plants, substations, and DER. There are active efforts to include additional forecast related information into the weather models of IEC 61400-25, and there is an IEC TC57 Joint Task Group on Weather UCs including WG10, WG17, and JWG25. One of the current activities is the extension of IEC 61850 schedules (IEC/TR 61850-90-10) to be able to carry weather forecast information to DER plants and systems. Coordinate development of UCs with inputs from a wide range of industries including Renewable/DER, distribution utilities, ISO/RTO markets, and forecasters These weather information standards efforts are to a large extend uncoordinated and are in need of Smart Grid UCs to ensure coverage and interoperability for a wide range of Smart Grid weather and forecast information exchange requirements to support Smart Grid applications.

PAP-22: EV Fueling Submetering Requirements Separate metering of Personal Electric Vehicle loads Tracking of PEV electrical consumption for credits Utility monitoring PEV loads for predictive analysis Requirements and standards needed to specify: Accuracy, performance, security Utility revenue grade billing data & 3rd party billing Data formats and certification PAP-22 will compile the core requirements for sub metering as they apply to form factor, accuracy, performance, security, data format, and certification for embedded, portable and stationary applications. The primary focus of this effort is to define the requirements, identify gaps and coordinate with the SDO’s to develop standards for sub metering of EV electricity fuel consumption. Though submetering requirements are common to many end-uses, there is an immediate need to address EV specific requirements.
