For dynamic reactive power optimization, load variation should be taken into consideration under the constraint of maximal allowable daily operating times. It is a complex nonlinear programming problem. A novel concept, named optimal matching flow for minimal energy loss, is presented in this paper. Based on this concept, a fast algorithm is developed to determine optimal size of capacitor at different time. This approach can calculate the optimal size of capacitors at every time in one calculation process, so it is very efficient. To optimize devices’ switching time, an efficient heuristics based method is also proposed. Results from numerical examples prove this algorithm is practical and efficient.
