Adaptive DC bus voltage control for renewable energy production systems with uncertainties
This paper introduces an adaptive DC bus voltage control strategy for renewable energy systems, combining different energy storage devices, i.e., batteries, fuel cells, and supercapacitors. Multiple bidirectional DC-DC converters accurate control is achieved with no source voltage sensing, which reduces the number of sensors. Unlike many adaptive controllers, the proposed strategy uses a single adaptive parameter, which yields reduced complexity. The proposed approach is compared to a classical PI-based cascaded control scheme. The adaptive control strategy achieves better performance, which yields a high-efficiency operation of the overall system.
