Proposed Modified PID Load Frequency Controller for Two Area Interconnected System Employing Frequency Regulation Techniques of Wind Power Plant

Abstract

Abstract

Frequent switching of load introduces noisy ambiances and makes the implementation of conventional PID controller challenging, as differential part of controller is noise sensitive. Thus, this paper proposes a modified PID load frequency controller for two area interconnected system, employing frequency regulation techniques of wind power plant, and compares the performance of modified PID load frequency controller with the conventional PID controller. Wind power plant with inertial control has been compared with combination of inertial and droop control. Modified PID controller has been simulated for wind turbine without frequency regulation capabilities and with inertial control as well as combination of inertial and droop control in MATLAB/SIMULINK ver. 2013. The significance of this work lies in the fact that it presents comparative analysis of different load frequency controllers and frequency regulation techniques of wind turbine in load frequency control regime, and shows reduction in frequency and tie line power deviations with frequency regulation techniques.
