Keywords:
Smart grid distribution system, power factor, dijkstra’s algorithm, feeder routingAbstract
The increment of reactive power is one of the most practical problems in power system. The increment of reactive power in distribution system causing low power factor or PF. The impacts of this problem are higher current in distribution line, higher power generation at the power plant, overloading current in devices, etc. Smart Grid can face the impact that found in the traditional grid. However, this problem of reactive power can be solved with the smart technology. This research proposed the dynamic feeder routing method to improve the maximum PF in the feeder of Smart Grid distribution. A modified version of Dijkstra’s algorithm applied to this research in order to decide and select a power route for each load cluster. New parameters included with the factor of impedance (FoI), the angle between active load and apparent power created as major factors for using in the method. The results of the proposed methods effectively reduced the variance of load fluctuation (FoS Variance) of all feeders as much as 51.16%. Moreover, the PF was higher base on reactive power that measured by the totality index in PF correction (PFAI Totality) of all feeders could be reduced as much as 38.42% with no exceeding in power rating of each feeder.
