源荷储多类型灵活性资源协调的高比例可再生能源电源规划 [PDF]
全球能源互联网, 2019 未来高比例可再生能源电力系统愿景下，具有波动性和不确定性的风/光等可再生能源作为主要能源供应者，给电力系统带来了巨大的灵活性需求，考虑单一类型灵活性资源提供调节能力的规划模型和以净负荷包络线为基础的电源规划方法将不再适用。引入灵活性指标量化评估源荷储多类型灵活性资源的调节潜力并作为优化决策变量纳入到规划模型中，从而建立以全周期投资成本最小化为目标的高比例可再生能源电源规划模型。通过电源投资决策、生产模拟和灵活性评估3个流程模块，实现单位投资改善灵活性指标最优的电源规划方案求解。最后 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT In conventional piezoceramics, the coordinated change between the dielectric constant (εr) and the piezoelectric charge constant (d33) usually limits the piezoelectric voltage constant g33 (g33 = d33/εr), a critical figure of merit for piezoelectric sensors.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...
