Load Frequency Control of Interconnected Hydro-Thermal Power System Using Fuzzy and Conventional PI Controller
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 8
Abstract
This paper shows how to regulate the power supply from interconnected hydro thermal power system by load frequency control (LFC). Thus the LFC helps in maintaining the scheduled system frequency and tie-line power interchange with the other areas within the prescribed limits. The load frequency of hydro thermal power system is controlled by both conventional PI and fuzzy logic controllers but the peak overshoot and settling time of fuzzy controller is less than that of conventional PI controller and this is clear from their results. The control strategies guarantees that the steady state error of frequencies and interchange of tie-lines power are maintained in a given tolerance limitations. The performances of these controllers are simulated using MATLAB/SIMULINK package.
