Abstract :
[en] This article examines the physical feasibility of DC
OPF based solutions when applied to power system planning.
Although widely used for its computational efficiency, the DC
OPF framework overlooks key constraints of the AC model,
which can lead to solutions that are not operationally viable. To
address these shortcomings, a rehabilitation methodology is de
veloped to ensure the full feasibility of the solutions obtained.The
proposed methodology is validated on a power grid representative
of an emerging country, namely Senegal. Such power systems are
characterized by rapid demand growth, a sparse grid, and limited
automatic control devices, making feasibility issues particularly
critical. The results demonstrate that explicitly accounting for
AC feasibility significantly improves the robustness and practical
applicability of the planning results.
