Steady-state voltage stability assessment of new energy power systems with multi-quadrant power modes

open access: yesEnergy Reports, 2023
The “source–load” attributes of the nodes in a new energy power system are complex and diverse due to a large amount of new energy access. The node power (active and reactive power) in the system can offer a changing mode, which causes several serious ...
