A Power Quality Improved Wind Energy Harvesting System For Standalone E Vehicle Battery Charging Applications

Abstract

The proposed battery charging method, which uses wind energy, is designed specifically for highway areas without access to the national grid, and its effectiveness has been shown in this study. The system under consideration is useful for charging stations located in remote places in highways and used for charging E vehicle batteries plying for long distances. This system design includes a permanent magnet synchronous generator (PMSG) that successfully absorbs wind energy and stores the harvested energy in a battery storage facility..The consumer’s E vehicle battery can be charged from the station batteries. The station batteries are charged throughout the day, whenever wind with sufficient wind velocity is available. The proposed system uses a controlled Active front end three phase converter so that the current drawn from the PMSG is sinusoidal and The power factor remains at unity, independent of the frequency associated with the AC voltage output generated by the Permanent Magnet Synchronous Generator (PMSG)., which is a function of the speed of the PMSG. Maximum power point tracking is achieved using the sliding mode controller methodology, which integrates wind speed with turbine speed, estimated indirectly through PMSG voltage output..The proposed system, developed using the MATLAB SIMULINK framework, has been validated through simulation outcomes, confirming its effectiveness.
