Load-flow solution by Newton-Richardson method and its adaptation to optimal load dispatch

By R. P. Aggarwal, N. Arumugam and M. A. Pai


A new load-flow solution technique based on the Newton-Richardson method is proposed, which is an attractive alternative for systems where the conventional Newton-Raphson method is preferred. The solution accuracy and the convergence rate are practically the same as in the Newton-Raphson method, while computing time is about half. It is also advantageous for optimum load-flow studies, since the Jacobian is easily available. The proposed technique has been tested for load flows on IEEE 14, 30 and 57 bus test systems and also on a heavily loaded 28 bus system. It is tested on an IEEE 30 bus system for optimal load flow
