Optimal Placement and Sizing of Series and Shunt Compensation for Improving Power Systems Operation
Power systems are complex, and power demand has constantly increased over time. Moreover, power transmission systems have a limited capacity, causing the increase in demand to be difficult to accommodate. Additional system requirements include maintaining voltages within specific values and limiting voltage drop in the lines to ensure voltage stability,
