Abstract

Communication of measured and forecasted weather data is important for many diverse Smart Grid applications. In fact, there are Use Cases (UCs) that illustrate the benefits of bidirectional weather data exchange. Today there are multiple Standards Setting Organizations (SSOs) with weather information exchange related standards development efforts. These efforts are uncoordinated and can benefit from collation of Smart Grid application UCs to ensure coverage and interoperability for the wide range of Smart Grid measured and forecasted weather information exchange requirements. This proposed Weather PAP will coordinate development of UCs with inputs from a wide range of industries including Renewable/DER, distribution utilities, ISO/RTO markets, and forecasters. It will produce a set of information requirements designed to facilitate the harmonization of information models and exchange models to be used in Smart Grid applications.

Key SSOs including Weather Exchange Model (WXXM) of the International Civil Aviation Organization (ICAO) and moving to World Meteorological Organization (WMO); International Electrotechnical Commission (IEC); and American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) will be active in the PAP. Additional SSOs will be identified and included as appropriate. Support will be provided by members of the SGIP DRGS DEWG and B2G DEWG.

Key Questions to Consider

• Who are the primary SSOs involved in weather information model development and how does the SGIP properly engage with all of them to coordinate and harmonize?
• Can the industry and SSOs in need of coordination for co-development of weather information models be successfully influenced to harmonize through the proposed PAP’s
  • use cases development, and,
  • cross-participation between weather information model efforts?
  • development of forecast scheduling information models to transfer forecasts
• Can the PAP help to foster interoperability through:
  • SGIP broad stakeholder participation and needs representation,
  • DRGS DEWG inputs from Renewables/DER, distribution utility, and ISO/RTO communities, and
  • B2G DEWG inputs for facility managers and building automation communities?
• Can the proposed PAP inspire a unified weather/forecast data information model and/or a well-defined weather information model development ecosystem to ensure interoperability through consistency?

Success Criteria

Harmonized standards for bi-directional exchange of weather information are produced in WMO, IEC, & ASHRAE and other identified SSOs. This enables a robust ecosystem for weather exchange between government, energy industry, and building management industry.

Description

Overview

Communication of measured and forecasted weather data is important for many diverse Smart Grid applications. Applications include bidirectional exchange of weather related information between wind/solar/CHP generators, buildings/facilities, sensors, forecasters and grid operators and among a variety of systems and applications within utilities.

A dominant application domain for weather is the international air traffic control system. Through international treaty and close coordination, weather information exchange is becoming a standardized commodity. As Smart Grid applications and system begin to rely more on weather data and incorporate more weather information exchange requirements, their associated standards require harmonization with weather information models used by the WMO. The Smart Grid adds a new dimension to the requirements of air traffic control and daily weather forecasting (initial focus of WXXM/WMO). As such WMO can be expected to add requirements or emphasis not previously driving the current international standards for meteorology. In particular, there is a need in Smart Grid applications for much more intensive treatment of uncertainty and statistical factors than is required for aviation.

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.

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.

There are multiple groups addressing weather information standards for Smart Grid:

• SGIP PAP 17 and B2G DEWG developed a White Paper in 2011 defining Weather Information Requirements for integrating buildings/facilities with Smart Grid which guided ASHRAE SCP201P to using an extension of WXXM.
• Recent PAP 16 discussions on wind plant and DER weather information model requirements included inputs from industry organizations active in this area such as SunSpec and AWEA, and these organizations provided documents related to their industry needs for weather information exchange. It was noted that bidirectional exchange of measured and forcasted weather information is needed for many applications. For example, weather forecast information may be needed at wind/solar generators for plant operations, and weather sensor data collected from wind/solar generators might also be communicated for use by forecasters, grid operators, and other wind plants.
• In view of the various emerging applications for weather information models and related SDO activities, the DRGS DEWG Subgroup B (DRGS UCs and Information Models Subgroup) identified Weather Data as the Highest Priority Gap and defined the general goals for UC development and model consistency.
• Furthermore, EPRI had a recent activity in collaboration with Sothern California Edison and IEC TC57 that considered many Use Cases relevant to the power industry. From these efforts and a survey of existing weather information exchange standards, they developed a top down derivation of a “CIM compliant” weather information model and a proposal for extension of the CIM (IEC 61970, 61968, 62325) to cover environmental data which is currently under consideration by TC57 WG16

To begin to define and address the recognized weather information model needs an SGIP Weather Task Group was formed. The SGIP has deemed that it is essential to move from today’s multiple independent SDOs developing weather information standards, to future coordination and co-development of weather information models. The strategy for doing this involves UC development and coordinated co-development of weather information models by the multiple SDOs. The long term vision is to develop a unified modeling approach and/or a well-defined weather information model development ecosystem to ensure consistency. The UCs developed and collected by the SGIP Weather PAP as well as the inputs provided by the SGIP Weather PAP stakeholder communities (including Renewable/DER, distribution utilities, ISO/RTOs, and forecasters) will provide the Smart Grid requirements for weather information model. The requirements defined by the PAP will be communicated to appropriate SSOs including WMO, IEC and ASHRAE.

• PAP 16 discussions of transmission wind plant and DER weather information model requirements:
• SunSpec, AWEA documents related to Weather Data
• Bidirectional weather information exchange:
  • weather sensor data collected at wind/solar generator/plant
  • forecast information for use at wind/solar generator/plant
• DRGS DEWG Subgroup B (UCs and Information models) identified Weather Data as Highest Priority Gap and defined goal of UC development and model consistency

What is the relationship to SSOs?

• WXXM general standard for weather data (from aviation)
  • moving to the WMO to become an international standard
  • based on core models of Open Geospatial Consortium
  • SGIP could coordinate through National Weather Service
• ASHRAE SCP201P weather model based on WXXM with minor extensions e.g. solar irradiance, focused on loads
• IEC TC57 Joint Task Group (WG10, WG17, JWG25) on weather UCs
  • IEC 61850, 61400-25 include weather information from meteorological towers at power plants, substations, DER
  • “Adding Forecasts to the IEC 61400-25,” Giebel and Gehrke
  • what data is collected, where does it go, what is it used for
• IEC TC57 WG16
  • Extension to Common Information Model (IEC 61970, 61968, 62325) to cover environmental data under consideration

What is the relationship to other organizations?

• EPRI looking at
  • IEC 61850 for collecting weather data
  • UCs for forecasting generation, dispatch, and bidding
• California ISO asked if hour-ahead generation forecasts can be improved from 20% error using upstream meteorological tower data
• Southern California Edison, Solar Power Forecasting
• Argonne National Labs, Wind Power Forecasting
  • http://www.dis.anl.gov/projects/windpowerforecasting.html
• DOE SunShot Program on forecasting at sub-hourly, hourly, day
  • www1.eere.energy.gov/solar/sunshot/financial_opps_detail.html?sol_id=511

What is impact if this PAP is not fulfilled

• Concern that lack of coordination between WMO, IEC, ASHRAE will lead to Smart Grid interoperability issues, complexity in mapping between protocols, and trade barriers
• This SGIP Weather PAP will collect/develop Use Cases that will provide guidance to standards development and coordination: WMO, IEC, ASHRAE
