In an interconnected power system, if a load demand changes arbitrarily, both frequency and tie line power differs. The principle point of load frequency control is to minimize the transient varieties in these variables furthermore to ensure that their steady state error is zero. Numerous cutting edge control procedures are utilized to execute a solid controller. The goal of these control strategies is to create and convey control dependably by keeping up both voltage and frequency within reasonable extent. At the point when real power changes system frequency gets affected while reactive power is subject to variety in voltage esteem. That is the reason real and reactive powers are controlled independently. Control of load frequency controls the active power. The role of automatic generation control (AGC) in power system operations with reference to tie line power under normal operating conditions is analyzed. This thesis studies the reliability of various control techniques of load frequency control of the proposed system through simulation in the MATLAB-Simulink environment.
