Abstract

<p>This paper proposes a dynamic state estimation method for distribution systems using measurement values from IT switches and smart meters. In future distribution systems, introduction of solar power generations and electric vehicles is expected to increase complexity of directions and changes in the power flow. The proposed method is able to observe power flow directions in the distribution systems better than conventional state estimation methods without using smart meters. Furthermore, in order to observe complicated changes in the power flow, measurement values from smart meters with long measurement periods and delays are weighted to adjust their influence on the state estimation results for better performance in tracking power flow changes. The proposed method is verified to be more accurate for the voltage estimation than conventional methods through simulations assuming complicated distribution systems.</p>
