Abstract
The operating costs of electric power systems can be minimized through the application of optimal power flow. In this paper, an interior point based optimization algorithm is implemented to solve the optimal power flow (OPF) problems with multiple objective functions. This algorithm takes into consideration Security Constrained Optimal Power Flow (SCOPF), which known as an extension of optimal power flow (OPF). SCOPF helps to maintain the combined goal of economy and security of the power system. The improvement in system performance is developed based on cost reduction of power generation and power loss. The obtained results from the proposed technique have been compared with other results reported in the literature. To validate the proposed approach, IEEE-30 bus system has been studied.
