A primary requirement for the transmission system operator is an accurate knowledge of grid
parameters. Moreover, the availability of effective and accurate monitoring tools allows the …

Recent contributions have shown that two widely used formulations of the tap-changing
transformer model are controversial, as they generate dissimilar results depending on the …

This paper utilizes distributed multi-agent reinforcement learning (MARL) based optimization
technique to arrive at the efficient reactive power control (ERPC) in electric power systems …

Three-winding transformers equipped with on-load tap changers are widely used in power
systems. The impact of tap-changer control across the entire range of regulation from the …

The tap-changing transformer models used in steady-state power system studies have been
recognized as somehow controversial for a long period. Indeed, discrepant versions arise …

The thesis presents the development of methodologies for the simultaneous estimation of
network parameters (lines and transformers) and compensation of systematic errors of …

With environmental and policy pressure to move towards cleaner fuel sources, wind energy
is a proven technology that can be successfully implemented at the utility-scale and provide …

Tap-changing transformer models used in power system studies tend to neglect the change
in the short-circuit impedance of the device at the different tap positions. However, the …

La regulación de tensión es una de las preocupaciones más importantes a tener en cuenta
en el diseño y operación de redes eléctricas. Por esta razón, los transformadores con …

The model of regulating transformers used in classic power system studies, such as load
flow analysis or state estimation, is still debatable. A recent publication has demonstrated …
