Abstract

The increasing global demand for energy has popularized wind and solar photovoltaics, yet their reliance on climate conditions necessitates energy storage solutions like batteries or hydroelectric reservoirs. While large hydro projects face high costs and stringent regulations, hydro microgeneration systems offer a cost-effective alternative with reduced environmental impact. This paper introduces a microgrid design incorporating three converters combining solar PV and hydro sources, meeting grid standards. It presents the system's design, control methods, and validation through hardware-in-the-loop testing. The proposed Hydro-PV microgeneration system outperforms standard systems, especially during rainy periods, by ensuring off-grid operation without the need for additional batteries due to its dispatchable characteristics. This innovative approach enhances sustainability, efficiency, and grid compatibility while optimally utilizing both hydro and photovoltaic resources. Furthermore, the average model developed in the paper can be used to compare this method's benefits regarding battery storage in different regions.
