Description
Summary:•Superconducting Fault Current Limiter (SFCL).•Optimal combination between SFCL location and power system stabilizer.•Power system stability.•Short-circuit fault in electrical power system. In this paper, authors present a method to select the optimal combination between the type of the power system stabilizer (PSS) and the location of a Superconducting Fault Current Limiter (SFCL) in an Electrical Power Grid (EPG) to improve the transient stability in case of fault. The angular separation between generators rotors when different types of short-circuit appears in the EPG is used as the main criterion of the proposed method to select this optimal combination. To complete the study, the optimal resistive value of the SFCL is evaluated to improve the global stability of the EPG. Results show that an optimal combination between the type of PSS, the location of SFCL in the EPG and the resistive value of SFCL exists in order to obtain the smallest variation of the angular separation of generators rotors, i.e. the best stability of the power system in case of fault.
