Abstract

In this paper, an early attempt is made to design the optimal control technique based on discrete law for load frequency control (LFC) of an interconnected power delivery system having the electric power generation via hydro turbines in interconnected areas. In addition to above the effect of diverse sampling time on optimal LFC in discrete mode is also investigated. The performance evaluation of design LFC is carried out for standard load disturbance in one of the control area and the comparative analysis of diverse sampling time are shown via LFC responses, eigen values and closed loop feedback gains. At last, the unified power flow controller (UPFC) is added in series with the tie-line as well as the redox flow battery is integrated in area-2 of the interconnected system and the application results are assessed in order to show the merits of these devices in the enhancement of LFC performance.
