Abstract
The environmental problems such as global warming and contamination have prompted the usage of renewable energy sources (RES) as well as storage units in the modern power systems. Among several RES, the WECS is considered as a highly efficient system due to its numerous benefits such as ease of availability as well as pollution free. In this chapter, a switched-reluctance generator-based wind energy conversion system is proposed that reduces switching burdens in the grid and improves the average output power with reduced error. The system utilizes a DC-DC converter that generates improved efficiency with reduced switching stress thereby solving the problem of reverse voltage polarity. Further, an improved grey wolf optimization (GWO)-based PI controller is employed to reduce the error of mean power. The proposed approach is simulated as well as validated generating an enhanced efficiency of 98% and reduced THD of 2.2%. The obtained results clearly indicate a dynamic response with reduced harmonic content and low power factor that assures sustainable energy.
