Abstract: In this paper, the influence characteristics of different types of measurements which aim to improve the accuracy of the state estimation in distribution system are studied through numerical tests. The causes for these influence characteristics are preliminary analyzed and discussed. Then, an optimization method for measurement configuration is proposed according to the foregoing analysis. The results of the numerical tests show that the proposed method can get promising results and is able to be used in optimizing the configuration of real-time measurement in distribution system.

Key words: distribution system, state estimation, measurement placement
