Abstract
The determination of economic benefits of increasing
transmission capability by dynamic line ratings is a
multifaceted task. In addition, there are many parties
concerned within the complex electricity markets. This
paper suggests a method for the evaluation of economic
feasibility and benefits, as well as for the minimum
potential assessment of employing dynamic line ratings.
The suggested deterministic method considers very
conservative assumptions in order not to compromise the
power system reliability, even though the method is
intended for the power system planning and not for the
operation purposes. The method is applicable for
congested transmission connections between electricity
market price areas and it is demonstrated with a distinct
case study of congestion on the power transmission from
Sweden to Finland. Despite the very conservative
assumptions used in the ampacity calculation to be on the
safe side, the method can clearly point out the
motivation to consider the implementation of dynamic line
ratings on congested transmission connections in order to
relieve bottlenecks and provide benefits for the society.
