Load flow solution of radial distribution feeders: a new contribution

Abstract

This paper presents a new development for solving the load flow problem for radial distribution feeders, without having to solve the well-known conventional load flow equations. The algorithm details are discussed. Two test radial distribution feeders are solved using the proposed development to illustrate the technique. The tables of solution variables such as voltage, injected powers at each node of the feeder and line losses are presented along with comments and conclusions. The performance of the proposed development is also evaluated for a number of feeders that were studied and solved using earlier methods. Also the method is compared with the original method from Baran and Wu (IEEE Trans. Power Delivery 4(1) (1989) 735–743) as well as the standard conventional load flow methods.
