Distribution network pseudo measurement generating method based on kernel density estimation

The invention relates to an interpolation method applied to pseudo measurement generating and belongs to the fields of electricity system dispatching automation technologies and power grid simulation technologies. The method comprises the steps that firstly, load data collected by an electric quantity metering system are used as load measurement; an unknown predicted value is obtained by utilizing a certain algorithm; afterwards, the predicted value is utilized, historical data serve as a basis, and then an efficient equidistant-node interpolation method is combined; accordingly, the defects of a distribution network measurement device are made up for. According to the pseudo measurement generating method, the load data in the distribution network metering system are fully utilized, and the algorithm of the method is simple, and convergence performance is guaranteed; required accuracy can be always obtained based on an equidistant-node method as long as the distances between nodes are small enough; calculation is fast, the accuracy of a pseudo measurement load of a non-measurement point can reach or approach an actual measured value, the smoothness of the load data is maintained, and then the state estimation accuracy of a distribution network is improved.
