This paper explores the possibility of complementing a model for optimal siting and placement of the distributed energy resources in a microgrid with the dynamic line rating. Implementation of DLR has shown a decrease in investment costs as well as a reduced number of installed generators as opposed to the solution without DLR implementation.
Dynamic line ratings. Dynamic line rating (DLR) technology uses a real-time monitoring system to constantly calculate the varying line rating of a transmission line due to the changes in weather conditions.
