Comparison of Power System Transient Stability in PV Farm By PID And Fuzzy Gain Scheduling of PID Controller
نویسندگان
چکیده
The extensive expansion of large photovoltaic (PV) farms in power systems diminishes both system inertia and synchronizing coupling. Due to the occurrence of several faults, the power system transient stability may be damaged. However the transient stability is improved by the fast power controlling ability of the PV inverter. This paper focuses on the new application of large PV farms equipped with PID and Fuzzy Gain Scheduling of Proportional–Integral–Derivative (FGS-PID) controller to achieve transient stability of a multimachine power system. The FGS-PID and PID controllers are basically employed to control the PV inverter, such that the PV power output can be modulated to stabilize the transient power swing when the faults take place. The FGS-PID with PID controllers is compared and among those the most efficient controller to achieve transient stability is analyzed.
