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.,

Static Voltage Stability Assessment of the Kenyan Power Network
Journal of Electrical and Computer Engineering, Volume 2021, Issue 1, 2021., 2021 In recent years, the Kenyan Power Network has witnessed large growths in load demand. Although the increased load demand has somewhat been matched with an increase in transmission and generation capacity, the rate of expansion has not been matched with the rate of increase in load demand due to economic, environmental, and geographical constraints ...
