Steady-state Voltage Profile and Long-term Voltage Stability of Electrified Road with Wireless Dynamic Charging [PDF]
Proceedings of the Tenth ACM International Conference on Future Energy Systems, 2019 Wireless dynamic charging technologies are becoming a promising alternative solution to plug-in ones as they allow on-the-move charging for electric vehicles. From a power network point of view, this type of charging makes electric vehicles a new type of loads--the moving loads.

Identifying Long Term Voltage Stability Caused by Distribution Systems vs Transmission Systems [PDF]
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018 Monitoring the long term voltage stability of the power grid is necessary to ensure its secure operation. This paper presents a new phasor based methodology that distinguishes between long term voltage stability caused by distribution systems versus transmission systems.

A Framework for Robust Long-Term Voltage Stability of Distribution Systems [PDF]
IEEE Transactions on Smart Grid, 2019 Power injection uncertainties in distribution power grids, which are mostly induced by aggressive introduction of intermittent renewable sources, may drive the system away from normal operating regimes and potentially lead to the loss of long-term voltage stability (LTVS). Naturally, there is an ever increasing need for a tool for assessing the LTVS of

Long-term voltage stability with large-scale solar-photovoltaic (PV) generation
International Journal of Electrical Power & Energy Systems, 2020 Abstract The dynamic characteristics of power grids have substantially evolved over the last two decades due to the large-scale integration of power-electronic converter (PEC)-interfaced renewable energy sources (RESs). Therefore, the impact of PEC-interfaced RESs on power system stability must be thoroughly examined.

A feature-subspace-based ensemble method for estimating long-term voltage stability margins [PDF]
Electric Power Systems Research, 2022 This study proposes a methodology for online voltage stability monitoring using a feature subspace based ensemble approach. The overall idea is to use the input from varied feature selectors for the ensemble and aggregate their outputs. This approach is superior to conventional feature selection methods because it can handle stability issues that are ...
