摘要

岛屿独特的自然环境和日益频繁的极端灾害，加之气候变化的加剧，必然导致岛屿综合能源系统（IIES）的高故障概率，并使其检查和恢复过程恶化，从而对IIES的运行安全提出了重大挑战。为了降低台风及其次生灾害下电力系统的风险，提出了一种新的风险优化的灾前防御策略，即配置储能系统。首先，考虑台风及其次生灾害的综合影响，计算IIES的失效概率，并采用级联失效模型对IIES的整体失效概率进行评估；其次，对工业园区的风险和弹性进行了比较和讨论。在此基础上，提出了一种新的ES优化配置策略，以最大限度地降低台风及其次生灾害联合影响下IIES的风险，并通过IIES试验系统进行了验证。结果表明，与基于弹性的优化策略相比，ES部署后风险降低了26.4 %，总成本分别降低了15 %和27 %。本研究有助于在合理投资的前提下提高IIES的运行安全性和抗风险能力。

A risk-optimized pre-disaster defense strategy for island integrated energy systems based on energy storage configuration

The unique natural environment of islands and the increasing frequency of extreme disasters, exacerbated by climate change, will inevitably lead to high failure probabilities of Island Integrated Energy Systems (IIES), and deteriorate its inspection and recovery process, thus posing substantial challenges to the operational safety of IIES. To reduce the risk of IIES under typhoon and its secondary disasters, a novel risk-optimized pre-disaster defense strategy is proposed by configuring energy storages (ESs). Firstly, the failure probabilities of IIES are calculated by considering combined effects of typhoon and its secondary disaster, and the cascading failure model is used to evaluate overall failure probability of IIES. Secondly, the risk and resilience of IIES is compared and discussed. Followed by this, a new ES optimal configuration strategy is proposed to minimize the risk of IIES under the combined effects of typhoon and its secondary disasters, which is validated by a test IIES system. Results show that the risk is reduced by 26.4 % after ES deployment, and the overall cost is 15 % and 27 % less than the results of resilience-based optimization strategy. This study contributes to improving the operational safety and risk resistance capability of IIES with reasonable investment.
