Optimizing power generation from clusters of fluid turbines like wind turbines by coordinating their operations to improve efficiency and grid compliance. The method involves using sensors, controllers, and storage devices in each turbine to monitor and regulate power output. When turbines generate below a threshold, excess power is stored. When grid conditions allow, the stored power is released. This allows turbines to keep generating even in low wind conditions, while avoiding grid issues. The method also involves coordinating rectifier inputs, DC-DC converters, and AC inversion to balance voltages across turbines.

An impeller for wind turbines that maximizes power output at lower wind speeds and reduces blade size compared to conventional wind turbine rotors. The impeller has a rear ring with a central axis that the blades attach to.
