Summary:
This paper discusses the synchronization problem and it’s solutions for large scale power network systems. We analyze dynamical properties of power networks and derive the synchronization condition of electrical generators. First, we employ a termed Kron reduction method to derive swing equation, which describes states of generators. Second, the derived equation is reduced into Non-uniform Kuramoto model, and then, a synchronization condition is derived by using the reduced model. Finally, we have succeed in relaxing the synchronization condition by controlling power units. Effectiveness of the proposed condition is shown via numerical control simulations.
