《天使不敢涉足的地方》是爱德华·摩根·福斯特的第一部小说。小说以英国寡妇莉莉娅与意大利小伙吉诺的爱情故事为线索展开情节。在此过程中,作为主人公之一的菲利普在两种文化的交锋中,开始了一段心路历程,人格结构在不同的阶段也产生了动态的变化,经历了从压抑本我、盲目偏执的超我到完善自我的转变的过程,最终实现了人格结构的完善。菲利普人格结构完善的心路历程的背后,也是福斯特本人对当时英国文化价值观念的反思,及对意大利开放文化的吸收借鉴。

Optimization of Convolutional Neural Network Based on Improved Sparrow Algorithm for Flywheel Energy Storage System Loss in Small Sample

引用

Dianwang Jishu/Power System Technology 2025年第1期49卷 366-372页

作者： Wei, Le li, Chenglin fang, fang liu, Yubin School of Control and Computer Engineering North China Electric Power University Changping District Beijing 102206 China

Flywheel energy storage systems have standby losses and are unsuitable for long-term energy storage. Aiming at the economic index of flywheel loss, based on the small sample data of the operation of the flywheel energy storage system, a flywheel loss calculation model combining a Logistic chaotic sparrow optimization algorithm and a convolutional neural network was proposed. Firstly, the causes of flywheel loss were analyzed. Next, the flywheel operation data of Ningxia lingwu Power Plant was preprocessed, and the adversarial generation network was used for small-sample enrichment. Then, the loss model is established based on the convolutional neural network, the improved sparrow algorithm is used to optimize the hyperparameters of the model, and the superiority of the model is verified by comparison. Finally, simulation experiments show that the model can optimize the output of the flywheel energy storage system and reduce the flywheel loss. © 2025 Power System Technology Press.
