Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper proposes an approach for selecting an optimal placement and control variable setting by finding the worst contingencies for the recently proposed Interline Direct Current Power Flow Controller (IDC-PFC) in MultiTerminal High-Voltage DC (MT-HVDC) Grids based on Max Flow- Min Cut Theory. It is for Optimal PFCs’ placements that purposes to optimize the maximum capacities of the transmission grid. Optimal settings for finding the most critical HVDC lines in a meshed grid and deciding where to place the PFC afterward. The controllable Voltage Source Converters (VSC)s are computed by applying a sequential quadratic programming solver in MatLab to the developed security-based DC optimal power flow problem including several corrective constraints.
