According to the latest developments in smart grid infrastructures of recent modern networks, in this paper, end-consumers are presented as a means for participating in networks voltage distribution control. In this regard, for reactive power control of the smart grids, a distributed control approach is proposed as an efficient approach which improves computation burden of the problem, considerably. In the proposed approach, at first, e-decomposition technique is adopted to calculate sensitivities of bus voltage to the injected reactive power. Therefore, buses with strong voltage relation are considered as a region which divides the network to some voltage related regions. Afterwards, candidate buses for reactive power injection are identified for each one of the achieved region. It is noted that, candidate buses of the network are those with reasonably better response to the reactive power injection. Finally, genetic algorithm is applied to obtain optimal reactive power injection of each region. For better evaluation of the proposed distributed reactive power control model, the IEEE 33-bus test system which is commonly used in literature is applied here. Simulation results clearly illustrate the effectiveness of proposed voltage control framework in improving voltage profile of distribution networks.
