| 摘要: |
| 综合能源系统(IES)可以通过内部调度调节向电网购/售电功率，大量IES接入对配电网故障恢复的支援能力随之增强。针对当前配电网故障恢复未充分考虑IES主体利益需求的问题，提出了一种均衡综合能源聚合商与配电公司利益的配电网故障恢复方法。建立了配电网故障功率缺额计算与分配模型，实现了综合能源聚合商内部配电网功率缺额在各个IES之间的最优分配；考虑负荷损失量、网络损耗以及对综合能源聚合商的补偿费用，提出了综合能源聚合商与配电公司不同利益主体的博弈策略。算例仿真结果表明所提方法在满足综合能源聚合商利益的前提下能实现配电网故障最优恢复，同时表明电网与综合能源聚合商之间的电价补偿机制、IES接入规模对配电网故障恢复效果影响显著。 |

| Abstract: |
| Integrated energy system(IES) can adjust the power purchase/sale injected to power grid through internal flexible dispatching, and a large number of IES integration can improve the fault recovery capability of distribution network. To address the problem that the economic requirement of IES is not fully considered in fault recovery of distribution network, a distribution network fault recovery method that takes into account the benefits of both integrated energy aggregator(IEA) and distribution company is proposed. The calculation and distribution models of fault power gap in distribution network are developed, which provides the optimal distribution of power gap in distribution network within IEA among various IESs. The game strategy between IEA and distribution company is proposed, in which load shedding, network losses and compensation costs of IEA are comprehensively considered. Simulative results show that the proposed method provides a better fault recovery under the premise of satisfying the interests of IEA, as well as the price compensation mechanism between the power grid and IEA. |
