The main purpose of this paper is to investigate the possible interaction that may occur between the distributed static series compensator (DSSC) and the static synchronous compensator (STATCOM) when they operate concurrently in the power system. The modied relative gain array (MRGA) is implemented to analyze the interactions. The application of MRGA for the eective design of multiobjective controllers of the STATCOM and DSSC is demonstrated by 2 cases of study: the rst case includes the contradiction among the AC voltage control, DC link capacitor voltage control, and power oscillation damping controller of the STATCOM, and the second case is dedicated to the interaction between the dierent controllers of the DSSC and the STATCOM. The simulation results are carried out in PSCAD/EMTDC in order to verify the results obtained from MRGA analysis in both cases...

In addition, it is widely accepted that, the Sub-Synchronous Resonance (SSR) is another unfavorable dynamical phenomenon in power systems. In this study, the implementation of the DFIG in SSR mitigation will be investigated. The IEEE second benchmark model aggregated with a DFIG based wind farm is employed as the case study. Two different control methodologies are proposed: a Fuzzy Logic Damping Controller (FLDC) and a conventional damping controller (CDC) that are added to the main control loop of the DFIG in order to damp the SSR. To validate the results of SSR suppression via DFIG, several case studies are introduced based on changing the operation point of the system and duration of the fault. It has been shown that the DFIG can damp the SSR through both proposed methodolo-gies, but when the system operating point or fault duration is changed, the FLDC can present a cost-effective solution for SSR damping. The Fast Fourier Transform (FFT), simulation results, and a method based on performance index (PI) are conducted to compare two controllers through various cases in Matlab.

DSSC has the ability to adjust the impedance of the power line in order to increase the power transfer capacity. The injected voltage is implemented here for limiting the fault currents.
