| Title | Inertia Characterization and Measurement in Modern Power Grids Incorporating Grid-Forming Inverters |
| Summary | As Singapore transitions to a low-carbon, renewable-based power grid, traditional synchronous generators are being replaced by inverter-based resources. Unlike conventional power plants, these inverters lack inherent physical inertia, fundamentally redefining how grid inertia is measured and controlled. While grid-following (GFL) inverters depend on an external grid reference, grid-forming (GFM) inverters actively regulate voltage and frequency, making them critical for stabilizing low-inertia power systems. However, the collective impact of multiple GFM inverters on overall system inertia remains unclear, particularly in urban microgrids and islanded networks. This project investigates various equivalent inertia definitions and examines the influence of GFM inverters on frequency dynamics through simulation-based studies. By exploring advanced control strategies and coordination mechanisms, the research aims to assess the strengths and limitations of current approaches and provide critical insights into maintaining grid stability in modern power systems. |
