The Effect of Fuzzy Logic Controller on Power System Stability; a Comparison between Fuzzy Logic Gain Scheduling PID and Conventional PID Controller
نویسنده
چکیده
--This paper presents the application of a fuzzy Logic controlled to improve stability of power system. The system in this study is a two-area electrical interconnected power system. Also, in this paper, the effect of a conventional controller PID, and a fuzzy logic gain scheduling PID (FGPID) controller on power system stability are compared. The performance of these controllers in First, settling times and overshoots of the frequency deviation are compared. All the models are simulated by Matlab Simulink software. The simulation results show that the FL controller developed in this study performs better than the PID controller with respect to the settling time and overshoot, and absolute error integral of the frequency deviation. Keywords---Load–frequency control, Power system stability; Fuzzy logic controller

Adaptive fuzzy gain scheduling PID controller for maximum power point tracking of photovoltaic system
This paper proposes a methodology of designing a Maximum Power Point Tracking (MPPT) controller for photovoltaic systems (PV) using a Fuzzy Gain Scheduling of Proportional-Integral-Derivative (PID) type controller (FGS-PID) with adaptation of scaling factors (SF) for the input signals of FGS. The proposed adaptive FGS-PID method is based on a two-level control system architecture, which combine...
متن کاملFuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve
Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...
متن کاملHybrid Fuzzy-PID Application in Boilers to Obtain Optimum Efficiency
Many real time processes have complex, uncertain and nonlinear dynamics. Boilers are nonlinear, time varying, multi-input multi-output (MIMO) systems, whose states generally vary with operating conditions. The major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. Conventional controller p...
متن کاملDesign of a hybrid fuzzy logic proportional plus conventional integral-derivative controller
This paper presents approaches to the design of a hybrid fuzzy logic proportional plus conventional integralderivative (fuzzy P+ID) controller in an incremental form. This controller is constructed by using an incremental fuzzy logic controller in place of the proportional term in a conventional PID controller. By using the bounded-input/bounded-output “small gain theorem,” the sufficient condi...
