Abstract
This paper describes the topology of dual-stage T-type three-level energy storage Power Conversion System (PCS), analyzes the control objectives under on-grid/off-grid conditions, and proposes a multi-objective control strategy based on dual-stage T-type three-level PCS. It also assigns the control strategy of the two-stage converter and the switching logic in the on-grid/off-grid switching process. An optimal control strategy of on-grid current/off-grid voltage waveform based on Vector Proportional integral (VPI) controller is proposed. The experimental results show that the proposed control strategy achieves relevant control objectives and has good control effect.
