摘要
日益频发的极端自然灾害可能会造成海岛配电网长时间停电,通过卡车等交通工具将电池灵活配置在需要的站点有助于保障海岛配电网供电,减少停电损失。在恢复过程中极端天气可能会影响电池在各站点间的转移速度,导致站点之间的调度时间非整数小时。为了解决此问题,提出一种新的海岛配电网负荷恢复优化策略。首先,分析环境因素对可再生能源发电和电池传输时间的影响,在此基础上,提出一种协调调度步骤和非整数小时电池传输时间的双重状态决策方法;然后,基于小时调度步长提出一种集成电池调度决策和网络重构决策的最优海岛配电网负荷恢复模型;最后,通过仿真算例验证所提策略的有效性。
The high frequency of extreme natural disasters may cause long-term power outages in the island distribution network.The flexible deployment of batteries at the required sites through trucks and other vehicles can help ensure the power supply of the island distribution network and reduce power outage losses.During the recovery process,extreme weather may affect the transfer speed of batteries between sites,resulting in non-integer hours of scheduling time between sites.In order to solve this problem,this paper proposes a new optimization strategy for load restoration of island distribution network.First,the impact of environmental factors on renewable energy generation and battery transfer time is analyzed.On this basis,a dual-state decision-making method for coordinating scheduling steps and non-integer-hour battery transfer time is proposed.In addition,based on the 1-hour scheduling step length,an optimal island distribution network load recovery model that integrates battery scheduling decisions and network reconfiguration decisions is proposed.Finally,the effectiveness of the proposed strategy is verified by a simulation example.
