Abstract
Nowadays, several methods are discovered for providing an efficient and an undisturbed power supply to the customers. This process starts at the generating station which mainly deals with Optimal Power Flow (OPF) method. The OPF method is an important method used to increase the power flow between the buses in a power system. The OPF deals with finding an optimal operating point of a power system that minimizes the cost function in terms of generation cost or transmission loss. The goal of OPF is to find the optimal settings of a given power system network that optimizes a certain objective function while satisfying its power flow equations, system security, and equipment operating limits. FACTs controllers can also be used to increase the power flow between the buses by connecting them at suitable places in the transmission line. In this paper, a hybrid technique and ANN based OPF with UPFC is proposed. The proposed hybrid technique combines both the PSO and BBO algorithm. The optimal location of UPFC is determined by ANN. The proposed OPF technique tested with IEEE 30 bus system and the optimal power flow is analyzed.
