Valéria Monteiro de Souza

About

Valéria Monteiro de Souza received his B.Sc. and M.Sc. degrees in Electrical Engineering with focus on Electrical Power Systems from Federal University of Pará (UFPA), Brazil, in 2017 and 2019 respectively. She is currently a Ph.D. candidate at the Norwegian University of Science and Technology (NTNU), Norway, working within the department of Power System Operation and Analysis (PSOA). Her Ph.D. research is focused on the development of novel methods for detection and prevention of voltage instability events as a means to provide decision-making support to TSOs in the context of early-warning early-prevention systems. This research is part of the NEWEPS project. Her research interests include power systems modelling and analysis, voltage stability, voltage control and renewable energy sources.

Research

PSOA

Nordic Early Warning Early Prevention System (NEWEPS)

NEWEPS is a Nordic research Project for a more efficient digitalized Power System between Statnett and SvK. The project is carried out in collaboration with Sintef Energi, NTNU, KTH and RISE.

Publications

Comparison of Voltage Stability Indices Based on Synchronized PMU Measurements

This paper conducts the assessment and comparison of three well-established voltage stability indices in terms of different types of loads, line disconnection events, placement of monitoring devices and presence of noise in the PMU measurements.

Investigations on Secondary Voltage Control for Long-Term Reactive Power Management

This paper addresses SVR performance for post-fault, daily load following and voltage setpoint change scenarios. The approach improves system voltage profiles, ensures fair reactive power sharing among generators and reduces transmission-level losses.
