Integration of Flywheel Energy Storage to AGC of Two Area …
A two area power system of classical Elgerd model is considered in this work. In the past load frequency control (LFC) operations could not be executed, owing to certain constraints, mainly non-availability of stored energy despite support lent by inertia of generator rotors. Dynamic stability of power system necessarily requires a buffer in the event of sudden …
Cooperation Mode and Operation Strategy for the Union of …
Finally, a rolling-horizon energy balance strategy is developed to make the control decisions for the TGU-BESS union in response to the stochastic AGC signal. The effectiveness of the proposed method is demonstrated using the historical data from a real union with a 9MW/4.5 MWh BESS and a 350MW coal-fired generator.
