IEC Smart Grid Standardization Roadmap

semantic patterns of IEC 61850 are presumed. Therefore it is a perfect match and extensionof IEC 61850 in the wind power area. Part 3 specifies the abstract data models necessary todefine Client-Server relations. The concrete description of the data formats and protocols aredescribed in Part 4. Mappings are provided for the following communication solutions:• Web services• OPC-XML• IEC 61850-8-1• IEC 60870-5-101/104• DNP3IEC 61400-25 combined with IEC 61850 is the most promising and complete integration ofrenewable energies in the power grid. Since wind turbines are high-cost objects, therealization of standard-conform interfaces is not so price-sensitive as in other distributedenergy resources. Therefore a widespread implementation of IEC 61400-25 can be expected.IEC 61727, Photovoltaic (PV) systems - Characteristics of the utility interfaceTechnical connection standardsSpecification of connection conditions is often subject to regulation. However IEC TC 8 PT 1started work on the connection of distributed generation to distribution network.EMCIEC 61000-4-30, Electromagnetic compatibility (EMC) – Part 4-30: Testing and measurementtechniques – Power quality measurement methodsOther standards in useThere are a number of national connection standards for distributed generation, e.g. ENAEngineering Recommendations G83/1, G59/1, G75/1 in the UK, FNN Anschlussregeln inGermany etc. In Europe there is a draft TS currently being prepared by WG3 of CenelecTC8X, which specifies the generic requirements for connecting DG to the public distributionnetwork.In the US IEEE 1547, Standard for Interconnecting Distributed Resources with Electric PowerSystems, is used. The Energy Policy Act of 2005 established IEEE 1547 as the nationalstandard for the interconnection of distributed generation resources. Currently, there are sixcomplementary standards designed to expand upon or clarify the initial standard, two of whichare published, and the other four still in the draft phase.IEEE 1547.1, published in 2005, further describes the testing of the interconnection in orderto determine whether or not it conforms to standards.IEEE 1547.2 provides a technical background on the standard.IEEE 1547.3, published in 2007, details techniques for monitoring of distributed systems.IEEE 1547.4 is a guide for the design, operation, and integration of conforming systems.IEEE 1547.5 is designed for distributed sources larger than 10 MVA.IEEE 1547.6 describes practices for secondary network interconnections.4.3.6.4 GapsMapping to communication protocols (IEC 61850-8-x).Ed. 1.0 - 2009-12 71 /136
