Abstract: The aim of this study is the presentation of a new analytical formulation of the reactive energy compensation on distribution Feeders, which are characterised by their radial configuration. This study will be devoted to the determination of the optimal batteries size and location of a non-homogeneous main feeder without laterals. Due to the line resistance and reactance, the voltage is non-constant and then, for the network solution, it is required to know the voltage at each node and at the batteries location. On the basis of what has been just said and due to the radial type of the line, an iterative method based on the backward and forward sweeps is applied for the voltage calculation. The voltage rms values and phase-angles at all the nodes and on the capacitor banks are calculated. The mathematical models of the current distributions are made considering the line active and reactive power losses. New expressions for the power and energy loss reductions are used in the reactive energy optimisation process. The method is implemented and the results obtained then, are compared to those of authors having previously worked on the subject.
