Abstract

Power system economic operation and transmission transfer capability continue to gain importance due to the continuous increase of power system capacities and complex interconnections. The evaluations of economic operation and transmission transfer capability have many applications in power system planning, operation and real time control TMs work deals with the applications of optimization methods in these two areas of power systems. In this thesis, different optimization techniques are discussed. Optimal power flow, security constrained optimal power flow, transmission transfer capability, and transmission transfer capability during contingencies are evaluated for different power systems. Simultaneous transfer capability is also evaluated by the optimization methods. The results are presented to show the performance and application of the optimization methods. Sequential Quadratic Programming is selected and implemented as an optimization method for carrying out this research. Matlab Optimization Toolbox is used as a tool to implement the optimization methods. Case studies using different power system models presented in this these show that the optimization methods are efficient methods for power system optimization problems and satisfy the requirements of modem power systems, to meet the requirements of economic operation and transfer capability.
