| 摘要: |
| 针对有源配电网发生故障后的快速供电恢复需求，提出基于多代理技术的自愈恢复系统。该系统采用分层协调的恢复模式，由下层区域代理为本区域发起供电恢复进程，上层馈线代理协调处理下层代理间的冲突。提出功率平衡度和转供容量裕度指标，基于该指标，当配电网故障隔离后，非故障失电馈线被分解为多个独立的区域，自愈系统能通过微网聚合恢复失电区域的供电，还可利用联络开关对孤岛区域进行负荷转供，达成综合恢复供电的目标。在供电恢复过程中，同时考虑馈线电压和电流的约束限制，保证系统在故障恢复后的安全稳定运行。在DIgSILENT软件上搭建含分布式电源的4馈线配电系统，仿真结果验证了所提策略的可行性和有效性。 |

| Abstract: |
| Aiming at the fast service restoration requirement of active distribution network after fault, a self-healing service restoration system based on multi-agent technology is proposed. A hierarchical coordinated restoration mode is adopted in the system, and the regional service restoration process is initiated by the region agent of lower layer, while the conflict between the region agents is coordinated by the feeder agent of upper layer. The power balance and transfer capacity margin indexes are proposed, on this basis, the non-fault outage feeder is decomposed into several independent zones after the fault of distribution network is isolated, the self-healing system can restore service of outa-ge zone through microgrid aggregation, and utilize tie switch to transfer load of island zone, by which the service restoration can be comprehensively obtained. The voltage and current constraints of feeder are considered in the service restoration process to ensure the secure and stable system operation after fault restoration. A four-feeder distribution system with distributed generators is built in software of DIgSILENT, and the simulative results verify the feasibility and effectiveness of the proposed strategy. |
