        abstract = {Performance improvement of UPFC with reference to the transient stability and Dynamic stability enhancement incorporating Fuzzy Logic controller in place of proportional integral controller is analysed. The UPFC is embedded with a 3 level cascaded H Bridge inverter. The Response time taken by UPFC with fuzzy controller is very less. Cascaded H Bridge Inverters offer high level of Voltage Support , Low Switching Stress and Good Modularity. The system response to the  Reference commands or the correction commands is very faster when compared to PI controller based UPFC. This aspect is shown by calculating the times like settling time in all the four cases of faults like LG, LL, LLG, LLL and also even when the loads are changed from normal to highly Inductive and highly capacity.the UPFC help the Power System Network to Restore  normalcy in a less time. UPSC is connected to the IEEE 5 bus system between the buses 3 and 4 for checking its capabilities. The improvement in the performance of UPFC with fuzzy based controller over conventional PI controller is depicted in the end result. Simulations results prove that a FUZZY LOGIC Controller Based UPFC has a better performance rate then a PI Controller based UPFC. The Simulations are carried using MATLAB Software.},
