Distributed Energy Resources (DER)

This website provides information on the standardization of distributed power delivery systems.

The IEC TC 57 and TC 88 have published three crucial international standard series helping the utility in-dustry to improve managing, automate and monitor the electric power system delivery system, reduce costs for planning, engineering, operating, and managing, and contributing to reducing the proliferation of solu-tions, most of which were proprietary:

• IEC 61970 - Energy management system application program interface (EMS-API) - Part 301: Common Information Model (CIM)
  
  
• IEC 61850 - Communication networks and systems in substations
  
  
• IEC 61400-25 - Communications for monitoring and control of wind power plants (61850 extensions)
  

Current standardization activities deal with further application domains: Decentralized Energy Resources (DER), Hydro Power Systems, Power Quality Measurements, and Condition Monitoring.

The IEC TC 57 WG 17 (DER) has published first drafts for Decentralized Energy Resources:

• IEC 61850-7-420 - Communications Systems for Distributed Energy Resources (DER) -- DER Logical Nodes
  

The IEC 61850-7-420 defines extensions of the successful series IEC 61850 are crucial for the future electric power delivery systems.

The standard IEC 61850-7-420 comprises the communication with and within any distributed energy re-sources like photo voltaic systems, fuel cell systems, combined heat and power, etc. These systems are in-tegrated into the utility information and automation systems such that they are closely related to the stan-dard series IEC 61970 and IEC 61850.
