With the growing application of exible AC transmission systems (FACTS) and distributed FACTS (DFACTS), the coordinating problem of FACTS and D-FACTS controllers in joint operation must be considered in modern power systems. 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 effective 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 different 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 of study.
