This paper delves into the analysis of three damping controllers: the power system stabilizers (PSS) installed in synchronous generators, and two Power Oscillation Damping (POD) controllers, one with active power modulation (POD-P) and the other with reactive power modulation (POD-Q), typically installed in environments with high renewable penetration.</div><div>The main objective is to critically evaluate the comparative advantages of PSS, POD-P, and POD-Q controllers in local and inter-area oscillations by exploring their flexibility and performance under various initial conditions and oscillatory scenarios.

This research is of utmost importance as it aims to dampen different oscillations by employing uniform control parameters in the PSS, POD-P, and POD-Q controllers.

Therefore, developing reliable three-phase power flow algorithms for transmission and distribution (T&D) systems becomes more and more important for the reliable and safe operation of emerging power systems. Among the many three-phase power flow algorithms, Newton Raphson method (NRM) and its variants occupy a large share, due to their ability in dealing with multiple sources and looped sub-networks.

Moreover, with the wide use of intelligent electronic equipment, there is an increasing coupling between CPS during the restoration process. Therefore, a double-layer optimization problem has been applied to represent the restoration of CPS. A vehicle routing problem with time-window (VRPTW) is proposed to formulate the cyber restoration process in the upper layer, where the time-window constraints are used for general restriction of restoration priority. Physical failures are restored through the application of network reconfiguration, distributed energy resources (DERs), and mobile emergency resources (MERs) for different areas in the lower layer. Furthermore, the time-window modification (TWM) method is proposed to coordinate the restoration between two layers. By adjusting the restoration time-windows flexibly in a flexible manner based on the scale of physical failure, the cyber-physical cooperation is effectively realised, and the restoration costs for both systems reduce efficiently within limited computational time. Case studies with modified IEEE 33-node and 118-node systems are conducted to validate the effectiveness of the proposed approach. The reduction of calculation time by applying the TWM method is demonstrated by comparison.
