A hybrid calculation method combining different data sampling densities is proposed for the theoretical line loss calculation problem of distributed power sources connected to distribution networks.This method utilizes high-density real-time data collection from distributed power sources to calculate the real-time output power of each node load in the distribution network,effectively compensating for the shortcomings of traditional line loss algorithms that only rely on load electricity information and improving the accuracy of line loss calculation.The numerical analysis results in the IEEE 17 node distribution network system show that the algorithm has high accuracy.The simulation results show that this method can effectively reduce errors in various scenarios,fully utilizing the high-density data collection in the distribution network,and has strong practicality.Through this method,power grid companies can more accurately manage line losses,improve the economic efficiency of power grid operation,and provide reliable technical support for lean management of the power grid.
