Abstract
A power generation system includes a vanadium redox battery that interfaces with a control system to optimize performance and efficiency. The power generation system may include one or more wind turbine generators and one or more diesel fuel generators. The control system manages the vanadium redox battery's absorption and power generation to control system stability and system frequency. The control system further manages the operation of the wind turbine generators and diesel fuel generators to control system stability and voltage.
