摘要:
针对配电网中的谐波、无功、三相不平衡问题以及可再生能源发电需求,提出一种新型的三相四线制光伏系统。针对光伏阵列及储能介质采用一种新型的三电平DC/DC变换器,分析其控制方法、调制策略以及中点电位不平衡抑制方法。双向并网变流器采用三相四线二极管钳位三电平变换器,为实现电能质量调节及有功功率双向流动,提出一种改进型的指令电流运算方法。在理论分析基础上,利用MATLAB/Simulink对该光伏系统进行了建模仿真,验证了新方案的可行性及有效性。
Abstract:
In this paper, a novel three-phase four-wire photovoltaic system is proposed for the compensation of harmonic, reactive and three-phase unbalance in the distribution network and the demand for renewable energy generation. A novel three-level DC/DC converter is adopted for photovoltaic arrays and energy storage, and its control method, modulation strategy and neutral-point potential imbalance suppression method are provided. Three-phase four-wire diode-clamped three-level converter is adopted for the bidirectional grid-connected converter. In order to realize power quality condition and active power bidirectional flow, an improved reference current calculation method is proposed, and the grid-connected current tracking control method is analyzed. Based on the theoretical analysis, the photovoltaic system is modeled and simulated by MATLAB/Simulink, which verified the feasibility and validity of the novel scheme.
