| dc.description.abstract | Real and reactive power injections into the buses of an electric power system can be used to control voltages at system buses. The voltage changes caused by incremental changes in power injections can be estimated by using the sensitivities of bus voltages with respect to power injections. Based on this consideration, a second order sensitivity load flow technique has been developed in this thesis. Both the first and second order sensitivities are used. In the proposed technique, the voltage corrections are first computed using the first order sensitivities. The second order corrections are then calculated by using the first order corrections. The real and imaginary components of bus voltages are updated using the calculated first and second order corrections. The procedure is repeated until a converged solution is obtained. Two modifications for the second order sensitivity load flow technique are presented in the thesis. A constant Jacobian second order sensitivity load flow method has also been developed. The proposed second order sensitivity load flow techniques have been used for computing load flows of five test systems. The results of these studies are presented and are compared with those of the Newton-Raphson, Second Order and Fast Decoupled Load Flow techniques. | |
