Implementation of LFC in Multi Area Power Systems using Conventional Controller

Abstract: Nowadays bulk power system is consisted of multiple interconnected controllable areas. In Interconnected power system, small disturbance occurs in load at any areas that causes the fluctuation of frequency at each and every area. Also fluctuate the power flow between the different areas. So, the main objectives of LFC are to maintain the frequency to its nominal value and scheduled the power exchange between the areas. This can be achieved by the conventional controller. so here conventional PID controller used as a controller in two thermal and one hydro area interconnected power system. Make a MATLAB simulink for LFC in multi area interconnected power system. Analysis this system response with and without PID controller along with and without consideration of generation rate constraint.

Keywords: load frequency control LFC scheme, Automatic generation control AGC, , AC link parallel with DC link, Generation rate constraint, conventional PID controller
