The system not only converts DC storage energy to the loads or the grids bidirectionally, but also supplies high quality power, such as low total harmonic distortion (THD) current to the girds or the
Contact UsIn order to design PCS with capabilities of high quality, high power and parallel connection operation to meet the large-scale energy storage system, the hybrid control scheme is proposed in this paper. This paper is structured as follows.
Bidirectional DC/DC converters enable charging of the battery in the forward mode of operation and facilitate flow of power back to the grid from the battery during reverse mode of operation, which can be used to stabilize the grid during peak load periods.
The following four popular topologies were considered for analysis. Based on this study, the dual-active bridge was chosen for implementation in this reference design, owing to the ease of bidirectional operation, modular structure, competitive efficiency, and power density numbers with respect to other competing topologies.
The maximum power transfer in a dual-active bridge occurs at a phase shift of 90°. However, a high phase shift requires a high leakage inductance for power transfer. Using a high inductor leads to increased RMS currents in the primary and secondary side, which affects the efficiency of the converter.
