Subscribe/Renew Journal
This paper proposed a novel load flow technique using Newton-Raphson (NR) polar form method with hybrid bus. In the former literature bus admittance matrix, YBus , is used for the computation of the load flow problems, that will take more number of iterations to converge the problem. To overcome this drawback, in this paper a novel NR polar form method using hybrid bus,HBus is proposed. The NR polar form load flow equations using HBus are derived. Standard IEEE test system and Indian utility systems are used to demonstrate the performance of the proposed approach. The results for NR power flow problem are physically interpreted on the IEEE-30 bus, 103 and 140 Indian utility bus systems with supporting numerical and graphical results and also validated against existing methods. The results using proposed approach show their superiority over existing approaches.
