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 controlthe 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.

In view of the nonlinear characteristics of the hybrid energy storage system (HESS), a nonlinear control strategy based on feedback linearization theory is proposed. the control objectives of the strategy are battery/super capacitor current and DC bus voltage. Firstly, by analyzing the state equation of the circuit, the affine nonlinear model of the circuit is established. then, the input-output feedback linearization and sliding mode surface are designed to realize the current tracking control of the battery and super capacitor. Finally, the classic voltage closed-loop control is used to realize the bus voltage stability. the simulation model is established on Simulink, and the simulation results show that the proposed control strategy is effective.
