Research of reactive power optimization based on subspace bacterial colony chemotaxis algorithm to in distribution networks with distributed generation

The reactive power optimization with distributed generation was discussed.By integrating traditional capacitor reactive power compensation,the distribution generator was used in the reactive power optimization as a continuous adjustable reactive source.Combining subspace conception,the subspace bacterial colony chemotaxis algorithm was proposed,and the global optimization capability of algorithm was enhanced.The application of algorithm in IEEE33 system showed that reactive power optimization with distributed generation was better to reduce the system loss and improve the voltage level.The validity and possibility of the algorithm was also verified.
