Abstract :
The paper presents a method of designing a low order robust wide-area damping controller (WADC) for large-scale photovoltaic (PV) power plants. The controller design procedure is focused on designing a second-order wide-area damping controller by convex optimization method. A Hankel singular value (HSV) based hybrid signal selection method is also proposed for optimal selection of the control signal. The performance of the synthesized controller is investigated on a 16-machine 68-bus system, typically used for power system oscillation studies.
