Abstract :
This study presents the design, development and comprehensive analysis of voltage and frequency controllers (VFCs) for standalone wind energy conversion systems (SWECSs). An isolated asynchronous generator, a synchronous generator (SG) and a permanent magnet SG are used with these SWECSs. These VFCs are developed with three-phase generators driven through a wind turbine to feed three-phase and single-phase loads. A battery energy storage system is used invariably with each system configuration to facilitate load leveling under change in wind speeds and consumer loads. The performance of VFCs are demonstrated to validate its operation as a load leveler, load balancer, phase balancer, neutral current compensator and an active filter along with a VFC.
