Synopsis:

In this paper load frequency control (LFC) of two area power system in deregulated environment using PI controller was studied. A two area system is considered in which all areas are interconnected by normal AC tie-lines. In each area there are two GENCOs and two DISCOs. DISCOs can buy power from GENCOs in their own area or from other areas. In the proposed system the effects of bilateral contracts between DISCOs and GENCOs are also considered. The performance of the PI controller is tested on a deregulated two area load frequency control system for different operating conditions using MATLAB Simulink tool. The results show that performance of PI controller is effective in reducing steady state error.
