Ingeteam’s simulation models to expedite wind power grid integration

Ingeteam presented its advanced simulation models developed to address the complex grid stability and connectivity issues that come with the integration of wind power into global electricity transport infrastructures.

With each wind farm grid conditions demanding specific and stringent requirements, complex modelling is paramount to solve grid connectivity and stability challenges. In particular, the need to work with very low Short Circuit Ratio (SCR) or quality factor grids, as well as the existence of sub-synchronous and parallel resonances are significant challenges. To overcome these issues, it is indispensable to develop accurate modelling of the converter control loops, and its interaction with the grid through the use of Linear Time-Invariant (LTI) strategies. 

Both Software in the Loop (SiL) and Hardware in the Loop (HiL) systems are commonly used in the industry, but the advanced simulation models developed by Ingeteam as Linear Time-Invariant (LTI) allow for higher agility to run parameter sweeps and to test new algorithms. 

With the use of one state-space matrix, the stability and dynamic behaviour of the system can be obtained easily from the LTI model. To achieve this, Ingeteam characterizes all possible casuistic of the grid parameter variations and conditions, generates the LTI models for all the cases, and validates the solution through SiL and HiL systems.

Alberto Barcia, Commercial Director, Ingeteam’s Wind Business Unit commented: “Throughout the world, a broad range of grid codes are in constant evolution. As the amount of renewable power deployed globally continues to increase steadily, the critical issue of grid stability also becomes increasingly complex. Ingeteam’s advanced simulation models are the answer to the complex grid issues that come with a high penetration of wind power in transmission grids.
