Power system state estimation is classically formulated as a weighted least squares (WLS)
optimization problem over the real domain, with the state variables being the voltage …

With steadily increasing interest in enhancing large power systems' transient stability,
generator coherency identification has become critical for the dynamic equivalents …

Network reduction is an effective tool for reducing the complexity of many analysis, design,
and optimization problems. However, many of the conventional reduction methods, such as …

A new static equivalent method using border PMU measurements is proposed to effectively
retain various voltage and reactive power support characteristics of external network without …

Line flow calculation plays a critically important role to guarantee the stable operation of
power system in economic dispatch (ED) problems with line constraints. This paper presents …

The hybrid power system state estimation problem requires computing the state of the power
network using data from both legacy and phasor measurements. Recent research has …

This paper is concerned about the divergence of state estimation solution for multi-area
power grids. Such cases typically occur due to a single anomaly in the measurement set or …

The total transfer capability (TTC) calculation is restricted by limited information exchanges
in multi‐area power systems. This study presents a multi‐area TTC calculation method …

Considering the increasing scale of power systems and gradually coupling between
transmission networks (TNs) and distribution networks (DNs), a parallel and asynchronous …

Static security analysis (SSA) is a significant measure to verify the secure and stable
