| 摘要: |
| 为消除花瓣式配电网的故障阻塞，实现花瓣式配电网与园区综合能源系统(PIES)协同优化运行，提出了一种基于双层优化模型的故障自愈策略。分析了花瓣式配电网发生故障阻塞的原因及其与PIES功率交互的过程。设计了基于“重构-激励”双层优化模型的动态故障自愈策略流程。其中，考虑负载均衡度、网络损耗及开关操作简便性，建立了基于网络重构的上层优化模型；考虑配电系统运营商与PIES聚合商的利益均衡，引入主从博弈思想，通过激励电价实现双方博弈互动，建立了基于激励型需求响应的下层优化模型。使用MATLAB软件搭建算例模型进行仿真，结果表明所提策略有效消除了故障阻塞，实现了花瓣式配电网故障后快速自愈及优化运行。 |

| Abstract: |
| In order to eliminate fault congestion in petal-shaped distribution network and achieve coordinated and optimized operation between petal-shaped distribution network and park-level integrated energy system(PIES),a fault self-healing strategy based on a two-layer optimization model is proposed. The causes of fault congestion in petal-shaped distribution network and the power interaction process between petal-shaped distribution network and PIES are analyzed. A dynamic fault self-healing strategy process based on a “reconstruction-incentive” two-layer optimization model is designed. Considering load balancing, network loss and the simplicity of switch operations, an upper-level optimization model based on network reconstruction is established. Taking into account the balance of interests between petal-shaped distribution system operator and PIES aggregator, a master-slave game theory is introduced. Through incentive pricing, mutual game interaction between both parties is achieved, and a lower-level optimization model based on incentive-based demand response is established. MATLAB software is used to build an example model for simulation. The results demonstrate that the proposed strategy effectively eliminates fault congestion, achieving rapid self-healing and optimized operation of the petal-shaped distribution network after a fault. |
