Abstract

The neutral point clamped （NPC） three-level energy storage converter is studied by using simulation software and experimental equipment. Firstly, 1500 V HVDC energy storage system is established, which has high energy density, high power density, high system cycle efficiency, low cost and less floor area, and is gradually becoming the mainstream; Then, the model of single NPC three-level power conversion system （PCS） is established. Combined with the energy storage system, filter circuit and transformer, the basic structure of the power station is formed, and the model of energy storage power station is established by connecting multiple equipment in parallel; Finally, the full decoupling control strategy in dq coordinate system is used to control the output power of PCS, so as to realize the power interaction with the power grid. The simulation and experimental results show that the battery energy storage station can quickly switch the charging and discharging working states, accurately track the target power, and output the grid connected voltage with good waveform and low distortion rate, so as to realize the regulation of the power grid.
