Calculation Method of Line Loss in Distribution Network Considering Distributed Generation

The calculation method and equivalent relationship of Root Mean Square (RMS) current and average current in distribution network are briefly introduced, and the accurate loss calculation model of distribution network based on loop analysis method is inferred. Based on the assumption condition of the average current method, the error of the average current method is analyzed. For the distribution network containing distributed generation, the daily load curves of distributed generation are used for correcting calculation error, and the improved average current method is obtained. Finally, taking the distribution line in a certain area of ShanDong province as an example, the effectiveness of the proposed algorithm is verified.
