摘要:
相比传统电网,韧性城市电网展现出了出色的适应多种扰动和灾害的能力,但其复杂性也使得韧性城市电网风险预警面临更大的挑战,亟需大数据和机器学习等先进技术的引入。首先,构建韧性城市电网风险评估指标体系,采用主客观结合的综合赋权法对指标赋权,通过大数据技术获取的实时数据流得到韧性城市电网风险评估指标的动态权重;然后,构建韧性城市电网风险评估标准云,计算韧性城市电网风险等级隶属度,确定风险等级;最后,基于随机森林构建韧性城市电网风险预警模型,并进行算例分析,通过与其他模型对比,发现所构建的模型表现出高精度的特征。所建模型具有较好的风险预警效果,从而能够及时采取有效风险管控措施,保障韧性城市电网稳定运行。
