Robust State Estimation of Active Distribution Networks with Multi-source Measurements

Multi-Area State Estimation Based on PMU Measurements in Distribution Networks

State estimation in the energy management center of active distribution networks has attracted many attentions. Considering an increase in complexity and real-time management of active distribution networks and knowing the network information at each time instant are necessary. This article presents a two-step multi-area state estimation method in balanced active distribution networks. The prop...

SDP-based State Estimation of Multi-phase Active Distribution Networks using micro-PMUs

Distribution system state estimation (DSSE) is an essential tool for operation of distribution networks, the results of which enables the operator to have a thorough observation of the system. Thus, most distribution management systems (DMS) include a single-phase state estimator. However, single-phase state estimation is not able to address the unbalanced nature of a distribution system which ...

Modified Weighted Least Squares Method to Improve Active Distribution System State Estimation

The development of communications and telecommunications infrastructure, followed by the extension of a new generation of smart distribution grids, has brought real-time control of distribution systems to electrical industry professionals’ attention. Also, the increasing use of distributed generation (DG) resources and the need for participation in the system voltage control, which is possible ...

Active Distribution Networks Restoration after Extreme Events

After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units.  In order to solve this problem, this paper provides a restoration s...
