To fully consume the distributed photovoltaic (PV) while reducing the impact of electric vehicle charging on the distribution network, PV-storage-charging integrated systems are rapidly developing. However, the secondary harmonic current of the DC bus in a PV-storage-charging integrated system will cause problems such as oscillations of PV output power and an increase in the current stress on the switching tube. To ensure the efficiency and power density of the system while suppressing the secondary harmonic current, the performance of different power decoupling circuits is evaluated from several dimensions at first. Then, based on the selected circuit topology, a soft-switching modulation method and the corresponding closed-loop control strategy are proposed, which can effectively improve the harmonic current suppression capability while realizing the full-range zero-voltage switching (ZVS). Finally, the effectiveness of the power decoupling circuit and the proposed control strategy was verified by simulation and experimental results.

为充分消纳分布式光伏PV(photovoltaic)同时减小电动汽车充电对配电网的影响,光储充一体化系统迅速发展。光储充系统直流母线的二次谐波电流会造成光伏输出功率振荡、开关管电流应力增大等问题。为在抑制二次谐波电流的同时保证系统的效率和功率密度,首先从多个维度对不同功率解耦电路的性能进行评估。然后基于选定的电路拓扑,提出了一种软开关调制方法及相应的闭环控制策略,能够有效提高谐波电流抑制能力,实现全范围零电压开通ZVS(zero-voltage switching)。最后,通过仿真和实验验证了功率解耦电路及所提控制策略的有效性。

为充分消纳分布式光伏PV(photovoltaic)同时减小电动汽车充电对配电网的影响,光储充一体化系统迅速发展。光储充系统直流母线的二次谐波电流会造成光伏输出功率振荡、开关管电流应力增大等问题。为在抑制二次谐波电流的同时保证系统的效率和功率密度,首先从多个维度对不同功率解耦电路的性能进行评估。然后基于选定的电路拓扑,提出了一种软开关调制方法及相应的闭环控制策略,能够有效提高谐波电流抑制能力,实现全范围零电压开通ZVS(zero-voltage switching)。最后,通过仿真和实验验证了功率解耦电路及所提控制策略的有效性。

光储充一体化系统  /  功率解耦  /  谐波抑制  /  零电压开通

To fully consume the distributed photovoltaic (PV) while reducing the impact of electric vehicle charging on the distribution network, PV-storage-charging integrated systems are rapidly developing. However, the secondary harmonic current of the DC bus in a PV-storage-charging integrated system will cause problems such as oscillations of PV output power and an increase in the current stress on the switching tube. To ensure the efficiency and power density of the system while suppressing the secondary harmonic current, the performance of different power decoupling circuits is evaluated from several dimensions at first. Then, based on the selected circuit topology, a soft-switching modulation method and the corresponding closed-loop control strategy are proposed, which can effectively improve the harmonic current suppression capability while realizing the full-range zero-voltage switching (ZVS). Finally, the effectiveness of the power decoupling circuit and the proposed control strategy was verified by simulation and experimental results.
