Solar fridges for the developing world
As climate change leads to more electricity blackouts and brownouts, the reliability of everyday refrigeration is at risk. A new IEC Standard, together with solar innovations in Africa and Asia, demonstrates how cooling can continue when power grids falter.
Optimal sizing for AC multi-bus microgrids based on solar, storage
A French–Moroccan research group has developed a two-stage hierarchical techno-economic model to optimize AC multi-bus microgrids in remote areas. This microgrid configuration is more complex than that of standalone systems but offers several advantages in terms of cost efficiency and energy reliability.
