Hybrid algorithm based location of UPFC for voltage stability

Now a day's voltage instability problems in a power system have become one of the most important concerns in electrical domain. In order to rectify this problem, various type of FACTS controllers are used. Among them we tend to prefer UPFC controller as it proves to be a versatile FACTS Controllers. We conduct the load flow analysis on the IEEE 14 bus system using Newton Raphson method to find the voltage stability index and L-index. Based on the parameters obtained we locate the UPFC controller in the power system. Then we apply the Hybrid algorithm which incorporates Honey bee mating algorithm and Plant growth Simulation algorithm, to conduct the load flow analysis using Newton Raphson Method. Here we find that Hybrid optimization technique brings in results with more convergence.
