Under voltage load shedding using hybrid ABC-PSO algorithm for voltage stability enhancement [PDF]
Heliyon, 2021 Voltage collapse tends to occur due to the voltage instability created during large faults. As a last resort, under-voltage load shedding (UVLS) is performed after all the available power operation and control mechanisms have been exhausted.

A Lyapunov spectrum based hybrid static and dynamic approach for contingency ranking
IET Generation, Transmission &Distribution, Volume 17, Issue 16, Page 3706-3717, August 2023., 2023 This paper presents a novel combined static and dynamic method for contingency ranking which takes advantage of both techniques and shows the performance evaluation for the hybrid method using accuracy and efficiency as criteria. The proposed method uses three well‐known static indices and the Lyapunov spectrum based dynamic approach to select the ...

Voltage Stability Assessment and Control Using Indices and FACTS: A Comparative Review
Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 The problem of voltage stability is becoming a more acute and indispensable topic given the major and sensitive role it plays in the electrical system. It can be considered a major factor in the initiation of blackouts around the world. Hence, the need for reliable and fast tools to detect and control the approach of instability points throughout the ...

Energy Conversion and Economics, Volume 3, Issue 1, Page 38-49, February 2022., 2022 Abstract Power system instability primarily results from the deviation of the frequency from its predefined rated value. This deviation causes voltage collapse, which further leads to sudden blackouts of the power system network. It is often triggered by a lack of reactive capacity.

Comprehensive Approach to Mitigating Solar Photovoltaic Power Penetration Effects in a Microgrid
International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022 High solar photovoltaic (PV) penetration in the electrical grid can result in undesired effects on the voltage quality, leading to line loss and voltage magnitude increases. One of the main criteria to ensure the safe penetration of high‐power solar systems in the main grid is maintaining an acceptable voltage magnitude when a disturbance occurs (e.g.,

International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022 This article elaborates on a reduced switch count‐based inverter for a single‐stage solar photovoltaic (SPV) fed induction motor (IM) with sensorless speed control for water pumping applications. The traditional SPV‐fed IM for water pumping applications requires a six‐switch voltage source inverter (SSVSI) for transforming the DC power from the SPV ...
