OPTIMAL POWER FLOW SOLUTION USING INTERIOR POINT ALGORITHM

Abstract

The focus of this dissertation work is formulation and development of a mathematical framework for the solution of the Optimal Power Flow (OPF) based on Interior Point Algorithm. The OPF performs all system control while maintaining system security. System controls include generator megawatt outputs, while maintenance of system security ensures that no power system component's limits are violated. Both equalities and inequalities can be solved in a non-linear manner based on the Karush Kuhn-Tucker (KKT) conditions. The performance of Interior Point (IP) algorithm has been tested for IEEE 14 and IEEE 30 bus test case systems and the results so obtained are compared. with Sequential Quadratic Programming (SQP). IP algorithm is found to be efficient and can be extended to large size practical power systems.
