Robust frequency control in a renewablepenetrated power system: an adaptivefractional order-fuzzy approach
Purpose: Load frequency control (LFC) in today's modern power system is getting complex
due to intermittency in the output power of renewable energy sources along with substantial changes in the system parameters and loads. To address this problem
this paper proposes an adaptive fractional order (FO)-fuzzy-PID controller for LFC of a renewable penetrated power system. Design/methodology/approach: To examine the performance of the proposed adaptive FO-fuzzy-PID controller
four different types of controllers that includes optimal proportional-integral-derivative (PID) controller
optimal fractional order (FO)-PID controller
optimal fuzzy PID controller
optimal FO-fuzzy PID controller are compared with the proposed approach. The dynamic response of the system relies upon the parameters of these controllers
which are optimized by using teaching-learning based optimization (TLBO) algorithm. The simulations are carried out using MATLAB/SIMULINK software. Findings: The simulation outcomes reveal the supremacy of the proposed approach in dynamic performance improvement (in terms of settling time
overshoot and error reduction) over other controllers in the literature under different scenarios. Originality/value: In this paper
an adaptive FO-fuzzy-PId controller is proposed for LFC of a renewable penetrated power system. The main contribution of this work is
a maiden application has been made to tune all the possible parameters of fuzzy controller and FO-PID controller simultaneously to handle the uncertainties caused by renewable sources
load and parametric variations.
