Comparative analysis against a peak-only optimization confirms comparable peak-load performance within 5% of the dedicated benchmark, while the proposed formulation additionally achieves a Pearson fairness index of 0.85 and combined fairness index of 0.90. Against a dedicated congestion-minimization approach, the proposed formulation delivers higher system-wide line loading reduction without localized loading increases, resolves the worst-case voltage violation, and achieves superior demand-response fairness.
