To solve the problem of evaluation on low-voltage demand side operation state of the distribution network, this paper presents a kind of evaluation method based on measurement values of the smart meter. It firstly introduces the concept of loop impedance of the low-voltage power distribution network and evaluation rules for low-voltage demand side operation state based on loop impedance. Then according to the real-time voltage data table and the real-time current data table, it generates the real-time loop impedance data table and makes assessment for low-voltage demand side operation state. Finally, on the basis of real-time data and changes of medium and long term data, it verifies feasibility and effectiveness of the proposed method.
