针对地震灾害突发性、破坏性强,且次生灾害及余震等不确定因素持续干扰电力系统安全运行,影响电力市场稳定性与可靠性的问题,提出地震后电力市场恢复力评估及跨区域资源动态调配机制,为震后救援黄金窗口期高效响应提供技术支撑。从灾前、灾中、灾后三个维度选取23个电力市场恢复力评估指标,鉴于评估指标的模糊性,运用可变模糊算法计算各指标相对隶属度与综合权重,结合级别特征值向量确定电力市场恢复力指数,并依据指数范围划分恢复力等级。在此基础上,利用回归分析模型预测电力市场受灾点资源需求量,综合考虑需求量、供给量和地理距离,借助万有引力模型计算各受灾区域与物资储备点间的引力指数,以此确定资源调配优先级,构建跨区域资源动态调配机制。实验表明,方法对电力市场恢复力评估的决定系数超0.8,评估准确度高;对40个受灾点资源调度时,各区域资源周转周期低于3h,资源调配实时性较高,有效验证了方法的恢复力与资源调配效能。
In view of the sudden and destructive earthquake disasters, and the continuous interference of uncer‐tain factors such as secondary disasters and aftershocks on the safe operation of the power system,which affects the stability and reliability of the power market,the resilience assessment of the electricity market after the earthquake and the dynamic allocation mechanism of cross-regional resources are proposed to provide technical support for the efficient response during the golden window period of post-earthquake rescue. 23 resilience assessment indicators for the electricity market are selected from three dimensions of pre-disaster, during-disaster, and post-disaster. Given the fuzziness of the assessment indicators,the variable fuzzy algorithm is used to calculate the relative mem‐bership degree and comprehensive weight of each indicator. The resilience index for the electricity market is deter‐mined based on the level eigenvalue vector,and the resilience levels are divided according to the index range. On this basis,the regression analysis model is used to predict the resource demand of the disaster-stricken sites in the electricity market. Considering the demand,supply and geographical distance,the gravity index between the di‐saster-stricken areas and the material reserve points is calculated by using the gravity model, so as to determine the priority of resource allocation and establish the dynamic allocation mechanism of cross-regional resources. Ex‐periments show that the determination coefficient of the method for resilience assessment of the electricity market is over 0.8, and the evaluation accuracy is high. When scheduling resource for 40 disaster-stricken points, the re‐source turnover cycle in each region is less than 3 hours, and the real-time performance of resource allocation is high,which effectively verifies the resilience and resource allocation efficiency of the method.
