Cognitive Computation and Systems, Volume 5, Issue 3, Page 195-217, September 2023., 2023 Abstract Due to the improvement in power demand usage, the system causes more stress. Suitable placement of FACTS is introduced to improve power flows, stability, and power system security. An advanced optimal method has been introduced to resolve optimal power flow under various conditions.

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.,
