DNV GL Makes New Mobile Solution for Testing Controllers

DNV GL, a global quality assurance and risk management company, has successfully tested the first project through its mobile test stand solution for renewable energy park controllers.

The company has assessed the German OEM EnoEnergy’s Gridmaster park controller.

The park controllers coordinate tasks between components in the wind and solar farms to optimize the power output.

Now, the use of this new mobile solution will make testing of controllers on site and hence decreases opportunity cost and transportation cost of the components to be tested.

Commenting on the development, Andreas Schröter, Executive Vice President Central Europe, Mediterranean and Latin America at DNV GL – Energy, said that “the global energy transition will only succeed if it is financially viable. That is why increasing process efficiency and reducing logistics in renewable projects is instrumental in making renewable energy projects more economical for manufacturers.”

He further added that “we are pleased that our solution can be used not only in isolation as an individual component but also flexibly and internationally. In the future, it will thus be possible for both manufacturers and operators of grids and facilities to check individual third-party controllers or their park controllers.”

The simulation of real-life environments under laboratory conditions test the implementation of the control algorithms and the functioning of the controllers under comparable conditions that are suitable for certification.

Using a mobile test stand, the measurement of individual components not only eliminates earnings losses but is also safer and more accurate.

Compliance with grid connection conditions of park controllers (generating plant controllers) is crucial for stable grid supply. The tests to be carried out for verification purposes are arranged by turbine manufacturers, developers, plant operators or grid operators prior to commissioning.
