“…The intermittency in the power generated by WECSs has prompted the development of methods to mitigate frequency variations at a PCC. These methods include the maximum-power-point-tracking (MPPT) control and collector systems for multiple WECSs [7]- [9]. Other methods have proposed the use of energy storage units (fly-wheels, battery banks, etc.)…”

“…The fast response, modular structure, high efficiency, and cost effectiveness are sample advantages that can be offered by BSUs [13]. The advantages of BSUs have made them a good candidate for PMG-based WECSs, as discussed in references [9]- [16]. These works provide a common theme of wind farm sized BSUs, where BSUs can support centralized storage capacities.…”

This paper develops and tests the performance of a new structure for grid-connected permanent magnet generator (PMG)-based wind energy conversion systems (WECSs) that have battery storage units (BSUs). The new structure is called the split dc-bus, and it is designed to reduce the pulsations in PMG developed torque and fluctuations in the power delivered to the grid. The reduction in PMG torque pulsations is achieved by employing a 5-level ac-dc power electronic converter (PEC) as the generator-PEC, whose dc outputs are processed by a two-port active dc-link. This active dc-link charges the BSUs and supplies the discharging PEC. The reduction of fluctuations in the delivered power is achieved by discharging the BSUs at point-of-common-coupling (PCC). The generator-side PEC, dc-link, grid-side PEC, and discharging PEC, are operated by a supervisor droop controller. The split-dc bus PMG-based WECS is implemented for performance testing under different wind speeds and levels of power delivery. Test results demonstrate reductions in PMG torque pulsations, along with reductions in the power delivered to the grid. These features of the split-dc bus PMG-based WECS are found to be complimented with a minor sensitivity to the changes in wind speed and changes in the power delivered to the grid.

Summary A novel dual mode wind turbine driven hybrid energy storage scheme with electromagnet based mode changing operation is proposed in this article. The hybrid storage system includes a pump storage hydroelectric system (PSH) and a vanadium redox flow battery. The proposed system provides uninterrupted energy at stable voltage to consumers in an isolated microgrid. The system is capable in handling different effects of wind speed‐related uncertainties at the load end, up to a certain limit. Advantages of the system lie in its reliability, operation simplicity, robustness, and energy output at stable voltage irrespective of normal wind speed variation. The proposed system also provides an idea of efficient usage of renewable energy. This article documents the proposed system structure, operation strategy, mathematical modeling, and simulation result using real wind speed data. The proposed system is found to be viable, upon simulation with a variable loading pattern.
