Abstract: Introduction was made to the reactive power optimization of distribution network with distributed generation and the bacterial colony chemotaxis (BCC) algorithm was improved. This paper introduced the differential evolution operator and mixed mapping chaos model of linear power function to adjust the moving speed and perception range of bacteria dynamically. The improved BCC increased the calculation speed and the capability of global search. Case calculation results show that after the improved bacterial colony chemotaxis algorithm was optimized, the distribution network has the lowest network loss and the least iteration times.
Key words: improved bacterial colony chemotaxis algorithm; distributed generation; distribution network; reactive power optimization
