Load frequency control using fuzzy logic based controller in two area power system

Abstract

At the present time, when we are concerned about frequency variation of the power systems, especially the interconnected systems one. In an interconnected grid sys- tem, the load and power ow in tie-line are changing abruptly. Hence, a proper control system is needed for an interconnected system to mitigate this frequency variation, which can be attained by the help of Proportional Integral PI controller, Proportional Integral Derivative controller (PID) controller, fuzzy logic controller and other usual controllers as found in state-of-art literature. However, since the real system deals with variable load values, the fuzzy logic based controller works most e ciently in order to mitigate this frequency variations and attain the steady state value quickly. Hence, in this work, we consider fuzzy based controller and con- centrate on triangular membership functions to prepare the rule base for our study system, and then, we validate our ndings through Matlab/simulink simulations.
