Area-based coordinated power system frequency control scheme

The increasing penetration of inverter-connected renewable energy resources (RES) has increased the variability of active power supply and reduced the rotational inertia in the grid, resulting in faster system dynamics along with larger and more frequent frequency events. To mitigate these challenges, a fast, area-based coordinated control strategy is proposed. This optimization-based scheme partitions the power system into small areas, and utilizes fast, inverter-based resources in each area to estimate and correct load imbalances. The control strategy is validated on a detailed nonlinear 3-area power system model implemented on MATLAB’s SimPowerSystems.
