| 摘要: |
| 配电网中谐波失真问题日趋严峻。然而，目前谐波治理的有关研究通常只聚焦于单一设备的谐波抑制，忽略了设备间的协同优化，导致谐波治理存在效率有限、经济性不足的问题。因此，提出一种三相不平衡配电系统中电动汽车与光伏协同调度的多目标最优谐波潮流模型，在减小功率损耗与电压不平衡度的同时降低谐波失真度。然而，谐波变量的引入会增加非凸模型的收敛难度。为了解决该问题，将原最优谐波潮流模型解耦为最优潮流子模型与二次规划子模型，并利用交替优化的思想实现模型的快速求解。最后利用IEEE34节点系统与IEEE123节点系统验证了所提方法的有效性。 |

| Abstract: |
| Harmonic distortion in distribution networks is becoming increasingly severe. However, existing studies on harmonic mitigation typically focus on harmonic suppression from individual devices, neglecting coordinated optimization among multiple devices. This results in limited effectiveness and insufficient economic performance of harmonic mitigation strategies. To address this issue, a multi-objective optimal harmonic power flow model for three-phase unbalanced distribution systems based on collaborative scheduling of photovoltaic (PV) systems and electric vehicles (EV) is proposed. The model reduces power losses and voltage unbalance while simultaneously lowering harmonic distortion. However, the introduction of harmonic variables increases the convergence difficulty of the non-convex model. To overcome this challenge, the original optimal harmonic power flow model is decomposed into an optimal power flow sub-model and a quadratic programming sub-model, and an alternating optimization approach is employed to achieve fast and efficient solution. Finally, the efficacy of the proposed methodology is verified using the IEEE 34-bus and IEEE 123-bus systems. |
