This paper addresses the use of thyristors based solid-state transfer switches (SSTS) systems to increase efficiency power flows in medium-voltage distribution. Detail of SSTS in electric distribution systems modelling was demonstrated in graphical diagrams using MATLAB/SIMULINK. Circuit test at specific fault condition was carried out to verify the system side fault and prove the functionality of the proposed SSTS system for sensitive loads. The used controller based on the Park’s transformation for performing fast transfer between two feeders were demonstrated. Results of the proposed SSTS control system which monitors the voltage and current source employed fast load switching between two distribution feeders. It is observed that SSTS was evaluated under fault showed the fast detection and transfer time during the operation.
