| Research Abstract |
Stability analyses have been performed on the model system including Photo Voltaic system with considering the existence of the Fault Ride Through (FRT) capability. As a result, stability of the system with an infinite bus becomes better in the case that PV does not have FRT capability. On the other hand, stability of the system without an infinite bus becomes worse in the case that PV does not have FRT capability, in which synchronous generators in the system can be out-of-step in decelerating direction.
In addition, a new method with a notch filter applied has been developed which can decrease the power system frequency fluctuations by using inertia energy of wind turbines of variable speed wind generators in a wind farm, and its performance has been confirmed.
