| 摘要: |
| 为提高储能系统利用率，实现多目标控制，提出一种基于比例矢量比例积分（PVPI）控制的分频协调控制策略。利用PVPI控制所具有的频率选择特性，理论上实现对特定次频率分量的零稳态误差控制，使储能变流器提供功率的同时有选择性地补偿谐波、无功和不平衡电流，从而有效利用了储能系统，改善了微电网电能质量，减小了微电网接入对低压配网电能质量的影响。仿真结果证明了所提多目标分频控制策略的有效性。 |

| Abstract: |
| A strategy of frequency-dividing control based on PVPI（Proportional Vector PI） control is pro-posed to enhance the utilization rate of energy storage system and achieve its multi-objective control. The frequency selection characteristics of PVPI control are used to theoretically realize the zero steady-state error control of a special frequency component，by which，the energy storage system supplies power while compensates selectively the harmonic，unbalance and reactive currents，resulting in the improvement of microgrid power quality and the suppression of its impact on low-voltage distribution grid. Simulative results verify the validity of the proposed control strategy. |
