| 摘要: |
| 现有电动汽车有序充电控制均聚焦于对有功充电负荷的时空迁移而非消除，仍存在一定的运行越限风险；同时现有研究多基于三相平衡网络模型，而实际配电网是显著不平衡的。为此基于逆变器的无功注入和三相选择，提出了一种新型不平衡主动配电网电动汽车有序充电控制策略。首先定义了电动汽车充电控制的多目标优化模型，以实现最小化网损和充电成本、最大化无功收益的整体优化；接着计及逆变器无功注入和三相选择，提出了一种电动汽车优化协调控制策略，以实现电网24 h范围内运行的优化；最后基于某澳大利亚真实配电网开展详细仿真分析，验证所提电动汽车有序充电优化模型和协调策略的正确性和有效性。 |

| Abstract: |
| Current studies of PEV(Plug-in Electric Vehicle) coordinated charging control mainly focus on the shifting feature of charging instead of eliminating, and the risk of worse operation still exists. Also existing studies on PEV charging are commonly based on three-phase balanced network model, but practical distribution networks are obviously unbalanced. A novel coordinated strategy of PEV charging in unbalanced distribution networks is proposed based on the inverter’s reactive power support and three phase switching. A multi-objective optimization model of PEV charging is firstly proposed to minimize network loss, charging cost while maximizing user benefit from providing ancillary reactive service. Secondly, a coordinated control strategy of PEV considering the inverter’s reactive power support and three phase switching is presented to improve the network operation within 24 hours. Finally, detailed simulations based on a real Australian distribution network verify the correctness and effectiveness of the proposed coordinated PEV charging model and strategy. |
