The harmonic load flow calculation of distribution network with distributed power

With the introduction of more and more distributed power distribution network system, which will produce a series of power system, in which the harmonic analysis of distribution network in recent years has become the field of energy use in the power industry the main issues of concern one. Distributed power through the establishment of the harmonic model, the ideal theoretical derivation DG access to distribution networks, the system harmonic voltage distortion level changes; chain and distribution network of 33 nodes was simulated example, to verify the theoretical analysis of the correctness.
