Power grid with changeable frequency

I would like to create a power grid (with simscape/SimPowerSystems) in which the grid frequency can change after connecting/disconnecting loads. With this I want to analyze control strategies to stabilize the grid frequency. Does anyone has a clue?

Thanks!

(1) To measure grid frequency, use PLL block. Refer the following simpowersystems example: power_3phpll ---> type this command in MATLAB. This example contains discrete PLL block to measure grid frequency. (2) To connect/disconnect loads, use a 3 phase breaker. Refer the following example: power_3phlinereclose

In phasor mode simulation method if your grid model contains conventional synchronous generator, you can use the rotor speed deviations as grid frequency variations.
