چکیده
|
Distribution load flow (dlf) calculation is one of the most important tools in distribution networks. dlf tools must be able to perform fast calculations in real-time studies at the presence of distributed generators (dgs) in a smart grid environment even in conditions of change in the network topology. in this paper, a new method for dlf in radial active distribution networks is proposed. the method performs a very fast dlf using zooming algorithm associated with a fast-decoupled reactive power compensation (zafdrc) technique, not in all of the buses of the grid, causes to reduce the solution time, which is the most important issue in the real-time studies. the proposed method is based on the zooming algorithm and does not require to calculate the businjection to branch-current (bibc) matrix which reduces the computational burden and helps to decrease the solution time. the method is tested on the ieee 69-bus systems as a balanced network and the ieee 123-bus as a very unbalanced system. the results confirm the high accuracy and high speed of the proposed method.
