Coordinated Optimization Control Strategy for Thermal-Flywheel Multi-Machine Systems Considering Losses

To address issues such as resource wastage in flywheel scheduling and difficulties in practical implementation within current flywheel energy storage array power distribution strategies, this paper proposes a multi-array loss optimization control model. The controller allocates array reference power commands based on the nonlinear scale decomposition algorithm, while optimizing the control of flywheel units to achieve coordinated control within the array. Additionally, an optimization strategy based on the equal incremental rate algorithm is designed for the flywheel unit loss model. Simulation results demonstrate that compared to traditional power distribution strategies, the proposed approach enhances the array's ability to track commands over long time scales, achieves coordinated control of the flywheel array, reduces unit operational losses, and effectively prevents excessive disparities between arrays from affecting operational efficiency, showcasing practical engineering significance and value.
