Six standards have been approved for the Catalog of Standards (CoS) managed by the Smart Grid Interoperability Panel (SGIP). SGIP was set up by NIST to drive a consensus-based standards recommendation process for the smart grid. FERC has decided against mandating these standards for US electric power utilities, so these standards are recommended, not mandatory.
The first six entries in the Catalog of Standards include
- internet protocol standards, which will allow grid devices to exchange information;
- energy usage information standards, which will permit consumers to know the cost of energy used at a given time
- standards for vehicle charging stations, necessary for ensuring electric vehicles can be connected to power outlets
- use cases for communication between plug-in vehicles and the grid, to help ensure that the vehicles–which will draw heavy power loads–will not place undue strain on the grid
- requirements for upgrading smart meters, which will replace household electric meters
- guidelines for assessing standards for wireless communication devices, which will be needed for grid communication
Three additional standards are currently being voted on among the SGIP membership for inclusion in the Catalog of Standards.
This is relevant to substation automation systems. It defines the communication between intelligent electronic devices (IEDs) in the substation and the related system requirements. Substation automation is of core relevance for smart grid.
Defines a standard for common format for event data exchange (COMFEDE) for power systems, specifically a common format for data files used for the interchange of various types of event data collected from electrical power systems or power system models.
Energy Interop defines the interaction between smart grids and their end nodes, including smart buildings, enterprises, industry, homes, and vehicles, specifically the interoperable and standard exchange of signals for dynamic pricing, reliability, and emergencies.
