“…Recently, the bridge-type fault current limiter (BFCL) with different configurations and limiting impedances have been introduced as a cost-effective strategy to improve the transient stability and enhance the FRT capability of the power system. Hossain et al [16] introduced a BFCL configuration comprising a series-connected resistor and inductor in parallel with a capacitor to augment the transient stability performance of a grid-connected wind power station. The obtained results showed the effectiveness of the employed BFCL compared with the series dynamic braking resistor (SDBR) and solidstate fault current limiter (SSFCL) during the 3LG and the 1LG faults.…”

This paper proposes an optimal design of Shunt-Resonance Fault Current Limiter (SRFCL) to enhance the Fault Ride-Through (FRT) capability and improve the transient stability of a grid-connected hybrid PV/wind power system. The design parameters of the SRFCL are optimized by using Particle Swarm Optimization (PSO) technique. The proposed SRFCL topology is designed in such a way that it can provide superior protection capability for limiting the fault current and supporting the grid voltage than the conventional Bridge Fault Current Limiter (BFCL). The effectiveness of the SRFCL in supporting the dynamic performance and improving the transient stability of the hybrid energy system is validated during both symmetrical and unsymmetrical faults in the electrical utility. Moreover, its credibility is evaluated compared with that of the BFCL and the FRT control schemes. Simulations have been performed using the MATLAB/SIMULINK software. The results illustrate that the proposed SRFCL augments significantly the dynamic behavior and the transient stability of the hybrid power system during the fault events. Also, when the optimal SRFCL is employed, the injected active power by the hybrid system and the grid voltage profile are improved considerably under the grid disturbances. Furthermore, the comparison confirms the superiority of the SRFCL performance to both the BFCL topology and the FRT control scheme in every aspect.
