Concoction of UPFC for optimal reactive power dispatch using hybrid GAPSO approach for power loss minimisation

The main motive of OPRD is to minimise the transmission loss along with control of voltage profile so that the voltage deviations at the load buses for variations in the loading conditions. With the concoction of FACTS devices, the power control can be finely achieved. The paper describes ORPD for the power loss minimisation using optimal concoction of UPFC and the cost of UPFC for ORPD. The power flow is first solved by NR method without concocting UPFC and then with concoction of UPFC randomly placed in the IEEE-30 bus system. The UPFC allows control of real and reactive power both in addition to voltage magnitude control at various buses. In this paper, OPRD is applied using the hybrid GA-PSO. Simulations are performed on IEEE-30 bus test system using MATLAB software package to ensure efficacy of the proposed algorithm. This paper aims at to find the optimum usage of UPFC which means the finding of the optimal location where their influence would be more useful as well as to determine their cost.
