- Pico-hydropower systems typically operate independently in off-grid locations, networking can increase cost, complexity and introduce instability. This is the first paper proposing and demonstrating stable control for an off-grid microgrid powered only by pico-hydropower. The paper introduces an original approach to share power dependent on the water flow availability and proposes a novel output harmonic voltage suppression method. This work has led to a British Academy grant (£196,000) with the microgrid group at Federal University of Pará, Brazil. A pilot implementation (https://youtu.be/JCslqoFK6Ms), published at European PV Solar Energy Conference, proved off-the-shelf components can be used to create a micro-grid.
