ABSTRACT

            In this paper, Improvement of voltage profile by using the Fuzzy Logic Controller (FLC) and Cuckoo Search (CS) based hybrid integrated technique is proposed. In the proposed technique generators voltage limits and Reactive Power Flows are developed by the FLC interference rules base. Because the generators minimal reactive power component is assessed that has been utilized to distribute its real power and effectively reduce the real power loss. The CS technique helps to optimize the minimized real power loss, while the reactive power operating points of the generator. It becomes to make the proposed technique as the integrated technique, because the optimized reactive power limits effectively maintains the voltage stability and reduce the line losses. The planned incorporated technique is applied in MATLAB working platform with IEEE 30 Bus test system, the voltage profile and optimal Power flows are presented.
