Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0036] The invention adopts the point estimation method to estimate the expected value of the node voltage, and uses the expected value to construct the training samples required by the elastic net algorithm, and determines the most influential dominant influence on the voltage of each node among the uncertain sources through the elastic net regression analysis of the node voltage Sources and their impact metrics. Then, according to the analysis requirements of the action mode, the node-uncertain influence source correlation matrix is constructed from the uncertainty source probability distribution characteristics and the node voltage regression equation, and the singular value decomposition i...
