| 1 | A soft actor-critic deep reinforcement learning method for multi-timescale coordinated operation of microgrids显示文摘This paper develops a multi-timescale coordinated operation method for microgrids based on modern deep rein-forcement learning.Considering the complementary characteristics of different storage devices,the proposed approach achieves multi-timescale coordination of battery and supercapacitor by introducing a hierarchical two-stage dispatch model.The first stage makes an initial decision irrespective of the uncertainties using the hourly predicted data to minimize the operational cost.For the second stage,it aims to generate corrective actions for the first-stage decisions to compensate for real-time renewable generation fluctuations.The first stage is formulated as a non-convex deterministic optimization problem,while the second stage is modeled as a Markov decision process solved by an entropy-regularized deep reinforcement learning method,i.e.,the Soft Actor-Critic.The Soft Actor-Critic method can efficiently address the exploration-exploitation dilemma and suppress variations.This improves the robustness of decisions.Simulation results demonstrate that different types of energy storage devices can be used at two stages to achieve the multi-timescale coordinated operation.This proves the effectiveness of the proposed method. | Chunchao Hu Zexiang Cai Yanxu Zhang Rudai Yan Yu Cai Bowei Cen | 2022 | Protection and Control of Modern Power Systems2022，7，1： | 2 |

| 4 | Controllable printing of large-scale compact perovskite films for flexible photodetectors显示文摘Perovskite materials are promising candidates for the next generation of wearable optoelectronics.However,due to uncontrolled crystallization and the natural brittle property of crystals,it remains a great challenge to fabricate large-scale compact and tough perovskite film.Here we report a facile method to print large-scale perovskite films with high quality for flexible photodetectors.By introducing a soluble polyethylene oxide(PEO)layer during the inkjet printing process,the nucleation and crystal growth of perovskite is well controlled.Perovskite films can be easily printed in large scale and patterned in high resolution.Moreover,this method can be extended to various kinds of perovskite materials,such as MAPbb(MA=methylammonium),MA_(3)Sb_(2)l_(9),and(BA)_(2)PbBr_(4)(BA=benzylammonium).The printed perovskite films show high quality and excellent mechanical performance.The photodetectors based on the MAPbBr3 perovskite films show a responsivity up to -1,036 mAA/V and maintain over 96.8%of the initial photocurrent after 15,000 consecutive bending cycles.This strategy provides a facile approach to prepare large-scale flexible perovskite films.It opens up new opportunities for the fabrication of diverse wearable optoelectronic devices. | Zhenkun Gu Ying Wang Shiheng Wang Ting Zhang Rudai Zhao Xiaotian Hu Zhandong Huang Meng Su Qun Xu Lihong Li Yiqiang Zhang Yanlin Song | 2022 | Nano Research2022，15，2： | 1 |

| 6 | A general method for growth of perovskite single-crystal arrays for high performance photodetectors显示文摘Perovskite single-crystal arrays have attracted intensive attention because of their great potentials for integrated optoelectronic devices.However,the traditional top-down lithography strategy requires complex processing and is detrimental to perovskite crystal structures,which is incompatible to directly pattern perovskite single crystals.Herein,we report a lithography-free method to realize the controllable growth of perovskite single-crystal arrays.Through introducing a printed hydrophilic-hydrophobic substrate into the crystallization system,the MAPbCl_(3) single-crystal arrays with precise location and uniform size are effectively fabricated.This method can be applied to prepare diverse perovskite single-crystal arrays,including MAPbBr_(3),CsPbCl_(3),CsPbBr_(3),Cs_(3)Cu_(2)I_(5),Cs_(3)Bi_(2)I_(9),and(BA)_(2)(MA)_(3)Pb_(4)I_(11).The perovskite single crystals can be selectively grown on the electrodes to fabricate ultraviolet photodetectors.The strategy demonstrates a facile approach to fabricate large-scale perovskite single-crystal arrays and opens a pathway to produce diverse perovskite optoelectronic devices. | Shiheng Wang Zhenkun Gu Rudai Zhao Ting Zhang Yunjie Lou Lutong Guo Meng Su Lihong Li Yiqiang Zhang Yanlin Song | 2022 | Nano Research2022，15，7： | 0 |
