Optimization of a power system with Interior Point method

Power flow or load flow solution is essential for continuous evaluation of the performance of the power systems so that suitable control measures can be taken in case of necessity. Load flow studies are made to plan the best operation and control of the existing system as well as plan the future expansion to keep pace with the load growth. Generally in any power system operation, our main aim is to operate a power system optimally. Optimality can be achieved by minimizing the cost, losses and maintaining voltage profile. So in order to achieve the above conditions that is to operate a system in an optimal way we choose various optimization techniques namely, optimal power flow by Newton method (OPF) and Interior Point (IP) method. In this paper a 5-BUS test system is taken and analyzed using the above mentioned two methods. It is shown that how the system power losses are decreased and voltage profiles are increased after using Interior Point (IP) method in this model. The results are generated for 5-Bus system.
