Abstract
This paper deals with major problem of load frequency control in two area deregulated hydro thermal system and unveils a new solution called sliding mode control strategy as an advanced technique. The proposed new control strategy will manage nonlinearities and uncertainties in the measurement of certain system states of the highly non linear power system. This optimal sliding mode controller tested on two area hydro thermal deregulated power system that includes bilateral contact when the system undergoes sudden disturbance. The performance of proposed new Optimal sliding mode controller has been compared with sliding mode observer based optimal controller and Conventional PI controller
