A power generation system with a predetermined rating limit includes one or more wind turbine generators and a vanadium redox battery. The vanadium redox battery absorbs excess energy to ensure that the rating limit is not exceeded, provide system stability, and improve power generation availability. The power generation system may further include a control system to manage the vanadium redox battery's absorption and power generation to control system stability and system frequency.
