Load frequency control (LFC) is a very important component in power system operation and control for supplying sufficient and reliable electric power with high quality. This paper addresses fuzzy logic controller for load frequency control of a two area power system. A deviation of frequency value from the standard (±0.5Hz) arises when real power generation fails to supply demand along with network losses. Various LFC studies have been done exploiting control strategies ranging from classical control schemes to soft analysis techniques. Conventional PI controller is designed and tuned with two techniques: using Ziegler Nichols (ZN) tuning and PID tuner app from MATLAB control system toolbox. Intelligent analysis tool, fuzzy logic, is used for performance improvement of the developed controller. Incorporation of advanced tools and optimization techniques improves control response time allowing fast recovery of the system during disturbances and reducing system down time. The system simulation is realized using MATLAB/ Simulink software. The comparison is done based on various performance indices like settling times and peak overshoots for 1 percent step load perturbation.
