This paper presents an approach to precisely estimate the Thevenin equivalent circuit (TEC) observed from a target bus by utilizing locally measured data. The proposed method relies solely on the voltage magnitude and the power transmitted through the target bus, enabling it to forecast TEC using data provided by WAMS and/or SCADA. Moreover, due to its reliance on local measurements, the proposed method serves as a suitable tool for distributed remedial action schemes to estimate the loadability margin and automatically execute corrective actions, even in the absence of wide-area measured data. Time-domain simulations conducted on Nordic32, IEEE 39-bus, and IEEE 33-bus distribution networks, and the comparison of these results with previously proposed methods in the literature, demonstrate that the proposed algorithm takes into account the system's topology and loading changes and accurately estimates the TEC in both transmission and distribution systems.
