Transient stabilization of power swing by controllable PV farm equipped with optimal fuzzy gain scheduling of PID controller
The severe faults in power systems may cause the power swing and transient instability. On the other hand, recently, the large photovoltaic (PV) farms have been extensively installed in power systems. With the ability of PV inverter, it is possible to control the PV output power quickly to stabilize the power swing. This paper proposes an optimal fuzzy gain scheduling of PID (FGS-PID) controller equipped with the PV inverter for stabilization of power swing. Without trial and error, the scale factors, membership functions and control rules of the FGS-PID controller are automatically obtained by a bee colony optimization. Simulation study in a single machine infinite bus system confirms the superior stabilizing effect of the PV with proposed FGS-PID in comparison to the PV with MPPT and the PV with PID.
