A New Method for Distribution State Estimation Accommodating Current Measurements
摘要
Abstract
This paper presented a state estimation method for distribution network which could accommodate the branch-current measurement without measurement conversion . In this method, the front end power and the square of branches' current amplitude were chosen as the unknown variables. Therefore, measurement equations are simplified. It's convenient to do with current measurement and no measurement conversion is needed. The voltage amplitude measurement, power measurement and current measurement are all can be formulated in the proposed method. An observation analysis method was also proposed for this estimation method which proves the new method having low measuring configuration requirements. Lastly, radial and weakly-meshed network examples show that the method is effective and practical.关键词
