Abstract: Introduction was made to the basic principles and methods of reactive power optimization. Analysis was made to thefeatures of reactive power optimization, such as multi-variable, multiple-constraint, non-convex and nonlinear. This paper builtthe target function with minimum grid losses, which made a compromise between the quality of voltage and the cost of device.The tabu search method in artificial intelligence and its improved algorithm were adopted and the IEEE30 node model was used to program, so as to carry out reactive power optimization for the system at certain definitive time. The results show that this reactive power optimization method can upgrade the economic effectiveness of grid.
Key words: reactive power optimization; tabu search method; voltage quality; active power losses
