This algorithm presented the special behavior of humpback whales during hunting process. This behavior is called bubble-net feeding method. The humpback whale went fell in water approximate 10-15 meter begin to produce bubbles in the spiral shape encircles prey and then follow the bubbles and moves upward the surface 30,31.
The steps involved in the optimization algorithmic of the particle swarm are as follows;
read system data(bus and branch data) and define the upper and lower bounds of the variables(location and size of DG and bus voltage)
Generate the initial population for each whales (a, A, C, I, p) randomly.
Calculate fitness of objective function for each search agent(P loss*, a, A, C, l, and p)
