OPTIMIZE THE POSITION AND SIZE OF THE DISTRIBUTED POWER SOURCE ON THE NON-BALANCED DISTRIBUTION GRID USING THE WHALE OPTIMIZATION ALGORITHM
This paper presents a method to optimize the position and size of distributed power sources (Distributed Generation - DG) on the Unbalanced Radial Distribution System (URDS). The proposed method uses the Whale Optimization Algorithm (WOA) optimization algorithm to optimize the position and size of DG to minimize the loss of active power on URDS. In addition to minimizing active power loss, the proposed method also improves the voltage at low voltage nodes on the distribution power system. The WOA algorithm mimics the behavior of whales foraging by attaching a bubble net. The special feature is that the brain cells in whales are similar to human cells called spindle cells and have more numbers than humans. With this feature and mechanism of the dolphin used to determine the optimal position and size of DG into URDS, it gives a global optimal solution. The results of this proposed method were examined in the problem of optimizing the position and size of DG on 25-node URDS and 37-node URDS showed the effectiveness of the proposed method.
