Chaos in Power Systems: Towards Short-term Voltage Stability Analysis
2018 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D-LA), 2018Power systems are highly non-linear and they sometimes may exhibit a chaotic dynamic behavior that leads to instability and subsequent voltage collapse. That is why the analysis of nonlinear dynamic systems using computational techniques based on chaos theory gives the possibility of detecting these instability phenomena.

A wide-area var-voltage control method for generators to improve short-term voltage stability
TENCON 2015 - 2015 IEEE Region 10 Conference, 2015The short-term voltage stability of receiving-end power systems is attracting considerable attention. One of effective solutions to this issue is to provide adequate dynamic reactive power for the system. This paper puts forward a reactive power-voltage (var-voltage) control method based on the wide area measurement system (WAMS).

Imbalance Learning Machine-Based Power System Short-Term Voltage Stability Assessment
IEEE Transactions on Industrial Informatics, 2017In terms of machine learning-based power system dynamic stability assessment, it is feasible to collect learning data from massive synchrophasor measurements in practice. However, the fact that instability events rarely occur would lead to a challenging class imbalance problem.

Demand-Response-Based Distributed Preventive Control to Improve Short-Term Voltage Stability
IEEE Transactions on Smart Grid, 2018Short-term voltage stability (STVS) issues pose a significant threat to modern power systems. Based on extensive observations of STVS events, their primary predictors can be summarized as summer peak load levels with a high percentage of air conditioners, and occurrence of faults caused by thunderstorms or other emergencies.

In the smart grid paradigm, growing integration of large-scale intermittent renewable energies has introduced significant uncertainties to the operations of an electric power system. This makes real-time dynamic security assessment (DSA) a necessity to enable enhanced situational-awareness against the risk of blackouts.

Impact of Dynamic Behavior of Photovoltaic Power Generation Systems on Short-Term Voltage Stability
IEEE Transactions on Power Systems, 2015In this study, we investigate the impact of the dynamic behavior of photovoltaic (PV) power generation systems on short-term voltage stability of the transmission system. First, the impact of the fault ride-through capability of a PV model is studied by setting several recovery speeds of the active current output when the operation of the PV system is ...
