System Stability and Grid Integration

We are your reliable partner for questions concerning

  • Stability investigations in transmission and distribution networks
    Network security assessment with dynamic models of networks, equipment and components (D.S.A.)
  • Metrological verification of the grid properties of decentralised generation plants (inverters, CHPs) and their components
  • SmartGrid applications: Hardware demonstration and performance evaluation
  • Performance of photovoltaic and hybrid systems and development of testing and measurement technology
  • Conceptual design of Smart Grid laboratories

We support you in

  • Creation of dynamic models of your grid
  • Creation and implementation of dynamic models of resources, generation plants, storage and loads
  • Development and implementation of tools for assessing system stability
  • Carrying out grid stability and grid integration studies with high proportions of grid-forming power converters and renewable energies
  • Measurement of the grid characteristics of power converters and CHPs according to various grid connection guidelines
  • Development-accompanying laboratory measurements on power converters (e.g. efficiency, electromagnetic compatibility, voltage quality, power behaviour, ageing etc.)
  • Specification and design of test environments
