PD IEC/TS 62950:2017

What is PD IEC/TS 62950 - Specifying smart capabilities, of appliances and devices about?  

PD IEC/TS 62950 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). PD IEC/TS 62950 does not set minimum requirements for appliances, SSESs or ODs. 
PD IEC/TS 62950 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). 

PD IEC/TS 62950: 

• Defines terms that describe the smart capabilities and smart operating modes of appliances, 
  SSESs and ODs 
• 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 
• Describes various approaches to measuring how the products respond in particular smart 
  operating modes. 

PD IEC/TS 62950 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.  

Note1: PD IEC/TS 62950 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. 

Note2: PD IEC/TS 62950 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. 

Who is PD IEC/TS 62950 - Specifying smart capabilities, of appliances and devices for? 

PD IEC/TS 62950 on smart appliances applies to: 

• Home energy management systems  manufacturers  
• Customer energy managers  
• Electrical household appliance manufacturers 
• Smart grid device manufacturers 
• Smart appliance manufacturers 

Why should you use PD IEC/TS 62950 - Specifying smart capabilities, of appliances and devices?  

Technologies related to "smart grids" have been emerging for some time, for a range of reasons, including the need to reduce greenhouse gas emissions, utilise renewable energy resources and increase the overall resilience and efficiency of the electricity supply system as a whole.  IEC TC 59 has considered the needs of the appliance market from a technology point of view and has identified products that will benefit from the potential for state-of-the-art technologies to add smart capabilities to household appliances, different architectures that may give rise to smart capabilities at a system-wide level, and the available protocols to control smart capabilities in household appliances and other devices. 

The goal of PD IEC/TS 62950 is to support the development of a global market for appliances with smart capabilities by: 

• Defining the terms associated with smart capabilities and smart operation so that appliances and devices might be described in their specific performance standards as having 'smart capabilities in accordance with IEC standard NNNNN' 
• Clarifying the points where information is exchanged between smart appliances and devices and the electricity grid 
• Defining the smart operating modes of appliances and devices in response to specific 
  conditions 
• Describing the general conditions for testing the smart operating modes of appliances and devices 
• Supporting sub-committees within TC59, and other technical committees and 
  standardization bodies, to include in their product specific performance standards descriptions of relevant smart capabilities and procedures for testing them and for measuring how other aspects of appliance performance might be affected by smart 
  operation
