基于参数自调节的电氢耦合系统调频控制策略研究

Gaoya dianqi
针对含质子交换膜燃料电池（proton exchange membrane fuel cell，PEMFC）的氢储能系统频率控制问题，为提高氢储能系统的频率稳定性，提出了一种基于虚拟参数自调节的系统频率控制策略。其中，电氢耦合系统以PEMFC为依托，光伏、储能电池为辅助，通过PEMFC、光伏、储能电池三者混合向系统综合负荷供电。通过数学模型构建，观察出系统内发生微小扰动后，PEMFC及储能电池的动态响应变化，改变虚拟控制参数，调整系统内的功率分配。由于PEMFC和储能电池动态响应时间不同 ...

基于C4.5决策树的国产化改造策略自适应评估模型

Dianxin kexue
信息技术发展推动国产化改造成为提升信息安全和自主可控能力的关键路径。提出了基于C4.5决策树与6R策略的国产化改造策略自适应评估模型，基于开发厂商、源码控制、CPU类型、操作系统及数据库等关键维度设计6R策略评估算法，结合C4.5决策树算法学习客户个性化配置方案，生成符合6R评估标准且满足需求的改造策略。实验表明该方法有效，整合6R策略与决策树算法，减少传统流程中手动调整环节，提升策略科学性与适配性。该方法精准识别系统特征与客户偏好关联，构建可复用技术框架，通过有限样本训练实现稳定输出 ...
