The mathematical representation of a new optimization algorithm and the method to recognize the optimality of the results, which based on functional transformations and generalized inverse of matrices, and the analysis model of probabilistic reactive power optimization were presented. Optimization technique was used in combination with stochastic production simulation and probabilistic simulation to study the rational configuration of reactive power compensation of power system. By using probabilistic and N - 1 and time reactive power optimization integrally, the optimizations are not refined to one or a few special operation modes and load levels, but meet the demands that the loads fluctuate stochastically or timely in the emergency or maintenance operation modes and in the total operation time. The case studies are provided.
