Grid conformity – Testing and Certification at the VDE Institute

The increasing expansion of energy networks with renewable energy poses new challenges to plant manufacturers, operators and grid operators alike. Compliance with connection conditions for grid feed-in is an important prerequisite for ensuring the stability and performance of electricity grids. The VDE Testing and Certification Institute offers you all the important tests and certifications related to grid conformity.

Connecting decentralized energy generation plants

If you wish to connect your plant to a medium, high or extra-high voltage grid, we are glad to assist you from the planning phase to supplying your plants at the appropriate grid level. At the same time, we assist you with our excellent contacts to grid operators, our consistently accepted system certificates from one source along with detailed and non-bureaucratic EZA declarations of conformity.

Our tests are based on these directives

We are accredited with DAKKS for the standards and directives listed below based on DIN EN ISO/IEC 17025 and DIN EN ISO/IEC 17065.

This accreditation also includes proof of competence in additional fundamental national and international standards and directives, a few examples of which are listed below:

 

  • E VDE-AR-N 4100: Technical connection rules for low voltage (draft)
  • VDE-AR-N 4105: Technical minimum requirements for connection and parallel operation of generating plants on the low-voltage grid
  • Directive from the Bundesverbandes der Energie- und Wasserwirtschaft e.V. (Germany Energy and Water Industry Association) (BDEW Directive)
  • E VDE-AR-N 4110: Technical connection rules for medium voltage (will replace the BDEW Directive in the future)
  • VDE AR-N-4120 (TAB high-voltage): Technical conditions for connecting and operating customer plants on the high-voltage network
  • Transmission Code 2007 (TC2007) Network and system rules from German transmission system operators (guidelines for connecting to a high or extra-high voltage network)
  • System service regulation – SDLWindV: Regulation on system services from wind turbines
  • Technical directives for generation units and plants Part 3: determining the electrical characteristics of generation units and plants on the medium, high and extra-high voltage network (development association for wind energy and other decentralized energies)
  • Technical directives for generation units and plants Part 4: Requirements for modeling and validating the simulation models of the electrical characteristics of generation units and plants (development association for wind energy and other decentralized energies)
  • Technical directives for generation units and plants Part 8: certifying the electrical characteristics of generation units and plants on the medium, high and extra-high voltage network (development association for wind energy and other decentralized energies)
  • Country-specific requirements for grid integration/grid code (e.g. Austria, France, Italy, Belgium, England, Australia, Europe)
