Selecting Candidate Buses in Distribution Grids for Distributed Voltage Control Considering End Users
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
According to the latest developments in smart grid infrastructures of today’s modern networks, in this paper, end-consumers are presented as a means for participating in distribution networks voltage control. In this regard, for reactive power control of the smart grids, a new algorithm for selecting candidate buses for injecting reactive power in distributed voltage control approach is proposed. In the distributed voltage control approach, at first, -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 for each one of the achieved region are identified by use of the proposed algorthim. 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 selecting candidate buse algorithm, the IEEE 33-bus test system which is commonly used in literature is applied here. Simulation results clearly illustrate the effectiveness of proposed algorithm in improving voltage profile of distribution networks.
