Enhancement of stability of the power system has been achieved by the application of Unified power flow controller (UPFC) device with an additional supplementary controller. This supplementary damping controller can be installed on any control channel of the UPFC inputs to implement the task of power oscillation damping (POD) controller. We have presented a comprehensive assessment and performe...

Nowadays, low frequency oscillation has become a major problem threatening the security of large-scale interconnected power systems.According to generationmechanism, active power oscillation of electric power systems can be classified into two categories: free oscillation and forced oscillation. The former results from poor or negative damping ratio of power system and external periodic disturb...

Power oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective...

Abstract— DC hubs are centrally located in DC grids and they are expected to operate autonomously under wide range of operating conditions. To achieve secure operation without intervention from dispatcher and to damp the internal oscillatory modes, a distributed power balance and damping controller for high power multiport LCL (Inductor-Capacitor-Inductor) DC hub is proposed in this paper. Nat...

Problem statement: The disturbance in the complicated network of power system may cause in nonlinear response. Static Synchronous Compensator (STATCOM) is a power electronic based device that has the capability of controlling the line current. This study applies the STATCOM to decrease the over line current in power system during dynamic state. Approach: This study proposes the control strategy...
