摘要：
In order to analyze the long-term characteristics of new power system,it is needed to carry out power flow calculation under multi-time section. A fast calculation method of multi-time section power flow based on holomorphic embedding is proposed,which realizes fast calculation of voltage amplitude and phase angle of multi-time section for distribution network with small errors. The numerical analysis of voltage power series coefficient in the holomorphic embedding method is carried out,and the linear calculation method of voltage power series coefficient is derived. On this basis,two fast power flow calculation modes of multi-time section are proposed. The test results of distribution network test system verify the effectiveness of the proposed method. © 2024 Electric Power Automation Equipment Press. All rights reserved.
