About the project
MITIGATE-HARM aims to ensure stable, secure, and reliable operation of future power systems dominated by power-electronics-based technologies and high shares of renewable energy. The project focuses on identifying, assessing, and mitigating converter-driven instabilities and harmonic resonances in large-scale hybrid AC/DC power systems, including multi-terminal and multi-vendor HVDC grids. By advancing fast, non-vendor-specific stability assessment tools, MITIGATE-HARM supports transmission system operators (TSOs) already at the early planning stages. The project further develops two open-source platforms, Harmony and DPsim, enabling impedance-based and eigenvalue-based stability analysis, rapid simulation, and systematic mitigation strategies. Ultimately, the project aims to enhance grid resilience, interoperability, and planning efficiency while facilitating the safe integration of up to 100% renewable energy.
