Abstract：It is one of the basic requirements of the smart distribution grid that improving the adaptability to distributed generation and having high economy and efficiency for distribution equipment. The probabilistic distribution and the power output ability of the grid-connected PV system are analyzed. The reactive power planning model based on the life cycle net present value and the reactive power output ability is established. The reactive power demand of the distribution network can be met with less reactive compensation. The improved algorithm based on the chaos multi-swarms particle swarm optimization algorithm is presented. The new algorithm’s global searching capability is improved. The new model and the algorithm are feasible and practical by a realistic reactive power planning project.
