在高影响低概率极端事件发生前实施合理的规划策略可以有效提升配电网的韧性。首先,根据对极端事件掌握信息的多少将决策者分为有信息支撑的较为保守的决策者和无信息支撑的极度保守的决策者。然后,针对有信息支撑的较为保守的决策者,以因台风而导致的极端事件为例,建立其对配电网影响的模型。提出将随机优化与信息间隙决策理论相结合的配电网韧性提升规划方法,分析其优势及适用范围。针对无信息支撑的极度保守的决策者,研究基于信息间隙决策理论风险规避策略的配电网韧性提升规划方法,并对配电网固有韧性进行分析。最后,在中国某地区实际94节点配电网中进行仿真验证。结果表明
在有限的资金预算下,所提方法可以适应两类决策者规避极端事件风险的不同偏好,生成最佳配电网韧性提升规划策略,将重要性加权甩负荷水平控制在阈值之下。
Reasonable planning strategies before the occurrence of extreme events with high impact and low probability can effectively enhance the resilience of distribution networks. First
according to the amount of the information of extreme events
decision-makers can be divided into relatively conservative decision-makers with information support and extremely conservative decision-makers without information support. Then
for the relatively conservative decision-makers with information support
the extreme events caused by the typhoon are taken as an example to build the model of its impact on the distribution network. A planning method for resilience enhancement of distribution networks that combines the information gap decision theory with stochastic optimization is proposed
and its benefits and application scope are analyzed. Furthermore
for the extremely conservative decision-makers without information support
the planning method for resilience enhancement of distribution networks based on the risk averse strategy of the information gap decision theory is studied
and the inherent resilience of distribution networks is analyzed. Finally
the simulation is carried out in a real 94-bus distribution network in a region of China. The results show that under the limited capital budget
the proposed method can adapt to the different preferences of the two types of decision-makers for avoiding the risk of extreme events
generate the optimal planning strategy for enhancing the resilience of distribution networks
and control the weighted load shedding level below the threshold.
