Tuning of the Parameters of PSS and IPFC-POD Controllers Using the Current Sensitivity Model

This paper presents a proposal for a coordinated adjustment of the parameters of supplementary damping con-trollers (Power System Stabilizers and Interline Power Flow Controller (IPFC)-Power Oscillation Damping (POD)) using the Multi-Start algorithm. The aim is to introduce additional damping to electromechanical oscillations present in electric power systems (EPSs). The current sensitivity model (CSM), is used to represent the EPS. The fundamental concept of the CSM is the nodal balance of currents at each time instant and in each bus of the power system. Thus, all devices and components of the EPS are modelled by current injection, including the IPFC. The solution is applied to a test system with 4 generators, 10 buses and 15 transmission lines divided into two areas with the presence of local and inter-area mode oscillations. The efficiency of the Multi-Start algo-rithm in adjusting the parameters of controllers can be concluded from the results.
