Abstract: |
This paper presents a method for managing congestion
constraints in a hydro-thermal optimal power flow
solution procedure. The congestion constraint is handled in
this paper as an active power generation constraint. To achieve
this solution, a power flow tracing technique is used to detect
the generators contributing to line congestion to penalize them
by reducing their outputs. The congestion is then removed by
setting the maximum power of the affected generators to the
penalized value. The proposed algorithm is implemented
using MATLAB software. Finally, the performance of the
proposed algorithm is tested and the results for the 5-bus,
30-bus, and 34-bus Nigerian power networks are presented. |
