Abstract
ABSTRACTWith the proviso that the nature of wind energy is intermittent, therefore, the usage of energy storage devices is vital to ensure continuous supply to loads and in particular when used in isolated grids. In this article, a permanent magnet synchronous generator (PMSG) driven by a wind turbine is used complete with lead-acid batteries. A topology of AC–DC–AC structure is adopted which is controlled by an efficient zero-current switching quasi-resonant boost converter for rechargeable batteries. This proposed configuration reduces the charging current ripples, and maximising battery life without enlarging the volume of the converter. A control scheme based-on a maximum power point tracker incorporated with PMSG is proposed to realize maximum power while maintaining the power balance, high efficiency power energy conversion and constant voltage and frequency at a three-phase load. The time-domain simulations and numerical results prove that the proposed scheme ensures maximum power, system stability and low ripples in the charging current compared to other conventional switching methods.
