IEC TS 62950

Abstract

This Technical Specification (TS) sets out a reference framework for defining and testing smart capabilities and smart operating modes of appliances, small scale energy supplies (SSESs) and other devices (ODs) (collectively termed \'smart devices\' if they have the defined capabilities). This document does not set minimum requirements for appliances, SSESs or ODs. This document focuses on electricity consumption but the principles and general architecture can be applied to other types of energy and other services. This document focuses on appliances, SSESs and ODs, but the principles and general architecture can also be applied to other products that are capable of being equipped with a device (energy) manager (DEM). This document: 1) defines terms that describe the smart capabilities and smart operating modes of appliances, SSESs and ODs; 2) describes the way in which such products respond to certain standard instructions and conditions that are likely to arise in the operation of smart grids; 3) describes various approaches to measuring how the products respond in particular smart operating modes. Although many examples are given in relation to particular product types, this document is not intended to fully describe these matters for any particular product type. This document is intended for use by IEC and other standardisation bodies who wish to address smart capabilities and smart operating modes in the performance standards for the products for which they are responsible. The smart device architecture and configurations described in this document, as illustrated in Figure 1 and Figure 2, are intended to guide but not necessarily limit the architecture for each specific product. This document is relevant to testing interactions between the customer energy manager (CEM) and the device energy manager (DEM) in configurations 1 and 2, insofar as they are relevant to determining the smart operation of a device. It does not cover the interactions between the DEM and a separate DEM-ready device (in configurations 2 and 3). For the time being, these interactions may be the subject of separate standards. This document does not cover configuration 4, in which the CEM-DEM interaction cannot be externally manipulated or observed in testing. In configuration 4, only the response of the product as a whole to grid information or remote agent instructions can be tested. This is beyond the scope of this document for the time being. NOTE: Communications methods and protocols are not within the scope of this document, but their consideration can be useful when applying this document in the development of specific product performance standards. The methods of communication are expected to be either left open, or limited to one or more existing methods and protocols, and be capable of supporting the configurations in Figure 1 and Figure 2, and the capabilities and smart operating modes in Table 1 and Table 2.
