Optimal Shunt-Resonance Fault Current Limiter for Transient Stability Enhancement of a Grid-Connected Hybrid PV/Wind Power System

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