Optimal tuning of PID controller for LFC of two area power system (PV-diesel) using bio-inspired optimization algorithms

摘要

This work presents a methodology for optimal parameter tuning of PID controller for frequency regulation in PV-Diesel two area power system. The gains of PV generator and diesel generator are optimized in a coordinated manner by employing biologically inspired optimized algorithms like Bat Algorithm (BA) and Firefly Algorithm (FA). Transfer function model of the diesel generator is interfaced with the photovoltaic system to create a two area hybrid power system. Load frequency control (LFC) of this two area hybrid power system is achieved by minimization of the objective function at different step load perturbation using optimization algorithms. Finally an analysis is carryout based on the obtained results. The simulation/coding of the entire system is performed in the MATLAB R2010a environment.
