Automatic Calculation and Simulation of Online Incremental Power Flow in 10kV Distribution Network Based on Approximate Ideal Solution

10kV distribution network is an important part directly connected with users in power system, and its power flow calculation and simulation analysis are of great significance to ensure the safe, reliable and economical operation of the power grid. Therefore, this paper presents an automatic calculation and simulation of online incremental power flow in 10kV distribution network based on approximate ideal solution. The objective function is to minimize the sum of squares of voltage deviation of all nodes, minimize the power loss of the whole network and approach the power factor as close as possible to 1. The objective function of online incremental power flow automatic calculation of 10kV distribution network is established, and each power flow solution is regarded as a scheme, and the solution closest to the ideal power flow state is found by approaching the ideal solution method. The evaluation matrix is dimensionless, and the automatic calculation of design power flow based on approximate ideal solution is realized The experimental results show that the confidence level of the research method is high, and the relative error between the expected value and the standard value is small under the conditions of active power flow and reactive power flow.
