Title: Research on standardization of new power system short circuit current calculation method
Abstract: The switching characteristics of power electronic equipment significantly change the characteristics of short-circuit current in power system, which challenges the traditional short-circuit current calculation methods. This report re-examines the principle of the superposition method for short-circuit current calculation of traditional AC system, and puts forward an improved engineering practical method. The short-circuit current characteristics of wind power generation, photovoltaic power generation and flexible DC transmission are analyzed, and the modeling method is proposed. For the new distribution network, an electromagnetic transient equivalent modeling method is proposed. The method proposed in the report will support the revision of national standards.

Title: New generation AI and its application in distribution network fault diagnosis
Abstract: Since large-scale renewable energy sources, flexible loads, power electronic equipment are interconnected to distribution networks, the fault process of distribution network become more and more nonlinear and random. On the basis of analyzing the fault characteristics of distribution network, this report compares the new-generation artificial intelligence technology with the traditional artificial intelligence technology, and discusses application methods of the new-generation artificial intelligence technology in fault diagnosis of distribution network. Different examples of new generation AI applications in fault diagnosis are given in this report and provide new solutions of using new generation AI in distribution networks.
