Summary:Nowadays, frequency control is becoming more important due to complicated changes in the size increase and structural changes in the grid. To ensure the power demand, the effectiveness and reliability of the power system must be enhanced, resulting in requirements to maintain frequency and current control of the power system has a value close to the set value. With a modern power system, load frequency control (LFC) operates with a necessary role as a stable device and aids in the exchange and improve the electrical quality of suppliers. In this paper, the author focuses on designing the Fuzzy-PI controller for superconducting magnetic energy storage (SMES) unit to control the fluctuation of frequency due to abruptness changes of load in the single-area and two-area system. In which PI controller is the main controller with Ki and Kp parameters, which are adjusted online by Fuzzy controller. The simulation results show that the overshoot, set time, oscillation amplitude of the FL-PI controller are superior to the conventional PI controller.
