IEEE 1547

The IEEE 1547 ( " IEEE Standard for Interconnecting Distributed Resources With Electric Power Systems ", dt, " IEEE standard for connecting distributed generation in electricity networks " ) is a standard that allows the networking of distributed generation, such as photovoltaic systems, and their integration into power grids of different range controls. It is for the supply and distribution of renewable energy is of particular importance, as these are produced locally in the vicinity of the consumers in many cases, for example citizen of solar cooperatives. The standard is part of a series of IEEE standards for the development of smart grids. The standard was prepared by the American Institute of Electrical and Electronics Engineers ( IEEE).

The IEEE -1547 series in the U.S.

The adopted in 2003 and 2008 confirmed networking standard IEEE 1547 has experienced due to the already highly developed in the future and more importantly becoming decentralization of energy essential supplements that are presented below together with the base standard.

Basic standard

The base standard IEEE 1547 contains criteria and standards of performance, operation, testing, safety, reliability and maintenance of energy networks. Thus, for example, Lower and upper limits to be observed for frequency ranges specified. This is particularly important because, for example by accidentally switching on and off of many small producers to strong frequency variations occur which can not be coped with by many consumers (see the 50.2 -Hertz problem). The standard is effective for networks up to 10 MVA. It was drawn up by the Energy Policy Act of 2005 as a national standard for the design of distributed power systems in the USA.

Additions to the basic standards

IEEE 1547.1-2005, " Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems ". The standard specifies requirements for testing of network functions and components of a distribution unit firmly on Compliance with IEEE 1547.

IEEE 1547.2-2008 "Application Guide for IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems ". This standard is a guide that is intended to support the understanding of the application of the standard IEEE 1547 different types of distributed generators.

IEEE 1547.3-2007 " Guide for Monitoring, Information Exchange, and Control of Distributed Resources Interconnected with Electric Power Systems ". The standard is designed to improve interoperability ( compatibility ) when connecting one or more distributed generation to a power grid. These include aspects of monitoring, information exchange and control of networked and distributed generators. These include fuel cells, photovoltaic systems, wind turbines and distributed energy storage.

IEEE 1547.4-2011 "Guide for Design, Operation, and Integration of Distributed Resource Iceland Systems with Electric Power Systems ". The standard includes different approaches and examples of the design and operation of power generators "islands " and their integration into power grids. This also includes the (temporary ) and separation of the re- connection to power networks, in order to increase the stability of the supply.

IEEE 1547.6-2011 " Recommended Practice For Interconnecting Distributed Resources with Electric Power Systems Distribution Secondary Networks ". This part of the standard aims to connect energy producers with distribution systems of second order, ie, from regional to local power grids. It includes recommendations regarding performance, operation, testing, safety and maintenance of regional and local power grids.

IEEE P1547.7 "Draft Guide to Conducting Distribution Impact Studies for Distributed Resource Interconnection ." The 2012 available only in draft standard describes tests to determine possible effects of distributed generators on regional networks. It describes criteria to reduce possible impacts. They should lead to a uniform assessment of potential risks and aimed at decentralized producers, owners and operators of regional networks as well as regulatory authorities.

IEEE P1547.8 "Recommended Practice for Establishing Methods and Procedures did Provide Supplemental Support for Implementation Strategies for Expanded Use of IEEE Standard 1547 ". The 2012 present only in draft standard specifies methods and procedures that allow for greater flexibility in the definition of further implementation strategies. This is aimed primarily on the integration of the production of solar energy and other renewable energy sources into the power infrastructure.

Related IEEE standards

IEEE 2030-2011 "Draft Guide for Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS), and End -Use Applications and Loads". The older standard IEEE 1547 is not yet explicitly to the extended requirements for the construction of a smart grid. In particular still lack the standardization of the role of information and communication technology in the intelligent integration of producers and consumers in the electricity networks. This is part of the standard IEEE 2030, which was published in September 2011.

Comparable standardization in Europe

In Europe, the standardization of the integration of distributed generators in power grids is not yet as advanced as in the U.S.. The reason is mainly in the many national regulations in this area. A European directive on this issue, there is not yet, however, there is a mandate from the European Commission for the standardization of smart grids.

Given the need for the use of decentralized renewable energies, see, eg, the energy turnaround in Germany, is now working intensively on standardization. At European level, the European Committee for Electrotechnical Standardization ( CENELEC) responsible, within the CENELEC Working Group 3 of the Technical Committee TC 8X (System aspects of electrical energy supply ). The goal is to reach as possible already in 2012 the first standard.
