This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to the studied power system. The effectiveness of the proposed PRBFCL in improving the transient stability and enhancing the dynamic performance of the hybrid power system is verified by applying both balanced and unbalanced faults in the power network. Also, its performance is compared with that of the bridge type fault current limiter (BFCL) and the fault ride through (FRT) schemes, i.e. FRT schemes of PV, DFIG, and with the AVR and governor of synchronous generator (SG). Some indexes are used to quantify the system performance. Simulation results obtained from the Matlab/Simulink software show that the proposed PRBFCL is effective in maintaining stable operation of the PV, wind generator, and synchronous generator during the grid fault. Moreover, the performance of the PRBFCL is better than that of the BFCL and the FRT methods in every aspect.
