The flywheel energy storage system topology studied in this paper is shown in Fig. 1, and consists of a flywheel with large inertia rotor, bearing system, vacuum chamber, housing, PMSM (motor/generator), machine-side converter, DC bus voltage stabilization capacitor, grid-side converter, filtering inductors, and other components.
Block diagram of the machine-side charge and discharge control of the flywheel energy storage system. The grid-side control strategy of the flywheel energy storage system combines grid voltage-oriented vector control and SVPWM (Space Vector Pulse Width Modulation) 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.
Most current research on SMO algorithms primarily focuses on motor control 30, whereas flywheel energy storage systems exhibit a more complex back-to-back structure, high operational speeds of the flywheel and motor, large system inertia, fast charging and discharging rates, and frequent switching of control strategies 31, 32.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
