Nov 1, 2024November 2024: Strengthened robustness and reliability of the WLS Delta_E state estimation in pandapower by introducing a safeguarding cap on delta_E at 0.35. This prevents divergence in extreme or ill-conditioned scenarios, improving convergence and stability of the weighted least squares estimation across diverse network conditions. The change reduces re-run failures and supports more trustworthy power system analyses for end users.
