摘要：

An interval power-flow equation based on the complex affine Ybus-Gaussian iteration is established, which applies the complex affine to describe the uncertainties of DG outputs and state variables. With the consideration of both efficiency and accuracy of interval power-flow calculation, similar noise elements are merged to suppress the noise element increase during the iteration. The complex affine is adopted to calculate the intervals of voltage amplitude and phase-angle. IEEE 33-bus system is applied to verify the effectiveness and correctness of the proposed method. © 2017, Electric Power Automation Equipment Press. All right reserved.
