An Improved Method for Power System Load Flow Analysis in New Power Systems

This paper proposes a new power grid load flow calculation method, which improves the traditional forward-backward sweep algorithm. It simplifies the establishment of the network mathematical model using the network matrices. It employs an adaptive threshold filtering method to process real-time acquired power grid data, overcoming the issues of disturbances in the new power system. The paper first introduces the process of establishing the power system mathematical model based on the network matrices, then explains the principles of the adaptive threshold filtering method, and subsequently provides a detailed description of the proposed method. Finally, a section of a 10kV distribution line in a city in China is selected as a case study to verify the feasibility of the proposed method.
