This project explored flywheel energy storage R&D to reach commercial viability for utility scale energy storage. This required advancing the design, manufacturing capability, system cost, storage capacity, efficiency, reliability, safety, and system level operation of flywheel energy storage technology.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
Installing 100 MW’s worth of flywheels used for distribution can reduce demand charges by $36 million and provide $8 million of energy savings a year since the FESS can eliminate mid-day peak and evening peaks of electricity use. Lithium battery technology can only do one peak reduction a day.
Furthermore, a multi-objective optimization scheme is proposed to minimize the flywheel energy losses along with the violated peak power of the feeder. Three different objective functions for applying peak shaving are presented and their efficiency is investigated in the simulation results.
