Unlike a traditional generator, a DFIG is fed with electrical power on both the rotor and stator sides, allowing for two-way power flow.

For compact, grid-connected setups, expect $3,000–$8,000 per installed kilowatt in many markets, with higher-end projects exceeding that when weatherproofing, control systems, and long-distance interconnections are required. Assumptions: region, specs, labor hours.

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity.

A microturbine (MT) is a small with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. Heavy gas turbine generators are too large and too expensive for distributed power applications, so MTs are developed for small-scale power like electrical power generation alone or as combined cooling, heating, and power (CCHP) systems. The.
