A frequency-based analysis tool to assess the stability margin in converter-dominated power systems to enhance integration of renewable energy sources

The integration of renewable energy sources in the power system causes power electronic converters to become a major part of the power grid.

As a result, the grid presents undesirable frequency characteristics that can initiate instability when connected to other dynamic components.

The aim of this project is to develop a frequency-based analytical tool to investigate and assess the stability in converter-dominated power systems.

By taking full advantage of the frequency characteristic of interconnected subsystems, the proposed approach can predict overall system stability for various grid scenarios.

From estimation of the stability margin of the interconnected system, important information can be provided to facilitate integration of renewable energy source to the power system.

The effectiveness of the proposed solution will be verified analytically, via simulation and over a small-scale laboratory setup.
