: The Electricity machine`s (PS) transmission line losses may be mitigated via way of means of Var compensation. The relevance and alertness of Flexible AC Transmission Systems (FACTS) gadgets for editing line strength flows to relieve congestion and decorate universal grid functioning have elevated because of the beginnings of energy markets with transmission accessibility. The maximum entire and multi-variable bendy ac transmission (FACTS) tool is the unified strength-go with the drift controller (UPFC). It can adjust all of the variables influencing the transmission line's strength go with the drift simultaneously or intelligently (i.e., voltage, impedance, and segment angle). In this study, the nice strength manipulates parameters for the UPFC machine are received the usage of the Ant Colony Optimization (ACO) approach. The simple manipulate method is such that the shunt converter controls the transmission-line reactive strength go with the drift and the dc-hyperlink voltage. The collection converter controls the transmission-line actual strength go with the drift and the UPFC bus voltage. The actual/reactive strength managed through (ACO) techniques with inside the UPFC manipulate machine can gain excellent overall performance each at some point of temporary and strong conditions. ACO is implemented concurrently on manipulate layers and consequences are in comparison with classical tuning approach and nicely set up ANFIS manipulate technique, Particle Swarm Optimization (PSO) the usage of MATLAB/Simulink software.
