Allocation of a variable series reactor considering AC constraints and contingencies

open access: yesCSEE Journal of Power and Energy Systems, 2019
The Variable Series Reactors (VSRs) can efficiently control the power flow through the adjustment of the line reactance. When they are appropriately allocated in the power network, the transmission congestion and generation cost can be reduced.
