Fulfillment the Low-voltage ride-through (LVRT) is required for wind farms (WFs) connected to the power system. This paper proposes simultaneous using both superconducting magnetic energy storage (SMES) and R-type solid-state fault current limiter (SSFCL) for enhancement the LVRT capability of WFs. The WFs is modeled with a doubly-fed induction generator (DFIG). The drive-train system is modeled by two-mass drive system. The analytical and simulation studies of using both SCES and R-type SSFCL for improving the LVRT capability of WFs are presented and compared with the impact of the Using the SMES alone. The simulation results show that simultaneous using both SCES and SSFCL effectively improves the LVRT capability of WFs connected to weak grids. Simulation were performed in PSCAD/EMTDC software environment.

Considering the outstanding use of renewable energy sources, most of industrial countries secure a main part of their required energy from renewable energy resources. Solar panels and wind turbines are the most important sources for the scattered production based on Renewable energies. In this study the optimized design of a solar panel, wind turbine hybrid system with superconductive magnetic energy storage (SMES), separated from network, to provide for the load demand of a military site is considered. The aim of a system optimization is specifying the number of solar panels, wind turbines, and SMESs with minimizing the cost of system's energy production. In hybrid systems, due to fluctuations in energy production of solar panels and wind turbines, accumulation systems are used in order to provide for a perpetual load. This system is also used to minimize annual costs of energy production for a system of load demand of a military site with the use of TLBO algorithm on a basis of teach-learn is being studied.
