Reconfiguration for load balancing of feeder in distribution system including distributed generation

AbstractThere are several types of load in distribution system. The load value that represents the varying load with time is needed to be estimated for reconfiguration because the system is reconfigured in non-real time. Specially, as the power system develops as the smart grid, the amount of distributed generations is increased. Since the variability of distributed generations’ output is higher compared to normal generations, it is important that which representative value is used for variable output when an algorithm performs. In addition, the reversed current caused by distributed generation should be considered. In this paper, we propose a method to choose representative value considering distribution generation and variable load and also a constraint considering the reversed current. By this method, we study the distribution system reconfiguration for reliable and efficient operating.
