Dual Active Bridge Bidirectional DC-DC Converter Modeling for Battery Energy Storage System

第37届中国控制会议

作者： Wei Chen yudi huang Xin Li Weiwei Zhang Ya Qiu Hefei University of Technology

Vanadium Redox Battery（VRB） has the advantages of large capacity, long life, safety and environmentally friendly. This paper proposes a double closed-loop charge-discharge control strategy of VRB based on cerebellar model arithmetic computer（CMAC） to ensure safe charge-discharge and shorten the charge-discharge time. The proposed control strategy consists of two main control loops: an outer voltage loop and an inner current loop. The outer control loop is designed as a voltage loop with CMAC controller which uses kernel voltage for feedback, and the inner current loop adopts PI regulator with amplitude limiting. In this paper, we first build a mathematical model of VRB of 5 kW/30 kW· h. Then, the proposed control strategy and conventional PID control strategy are respectively applied to VRB model and comparisons are made. Results show that under the proposed control strategy, charging time of VRB shortened by 3.03%, discharging time of VRB shortened by 9.37% compared with conventional PID control strategy, and the terminal voltage can be guaranteed in a safe range, thus realizing fast and safe charge-discharge of VRB.

“一带一路”国家基础设施状况对我国OFDI的影响——基于面板门槛模型的研究

第37届中国控制会议

作者： Xin Li Weiwei Zhang Wei Chen yudi huang Ya Qiu Hefei University of Technology

This paper studies the mathematical model of dual active bridge（DAB） DC-DC converter under the variations of bus voltage and battery voltage. In view of the fact that the DAB converter has a bounded change of the power supply voltage on the high-voltage side and a controllable change of the electromotive force（EMF） load on the low-voltage side, the power supply voltage on high-voltage side and the EMF load voltage on low-voltage side are taken as control variables. The states of DAB converter during a switching cycle are analyzed, and the averaged model（HL model） of the DAB converter under the condition of continuous conduction mode（CCM） is established as well as the small-signal model. The comparisons are made between the output voltage of the HL model and the topology circuit with simulation. And according to the small-signal model, the dynamic performance of the DAB converter is analyzed under the variations of the power supply voltage, the EMF load and phase-shift radio. The result shows that the proposed HL model has the same steady and dynamic performance as the circuit topology model. The relative error of the model at steady state is only 0.35%. Therefore, the applicability and the accuracy of the proposed model in battery energy storage system can be verified.

"一带一路"倡议的实施不仅标志着中国对外开放步入更高的经济开放水平,而且还强调了基础设施建设对于沿线国家与中国共同发展、实现共赢的积极意义。文章基于"一带一路"沿线60个国家的数据,将"一带一路"国家基础设施发展状况作为核心变量,利用面板门槛模型,分析其在吸引我国对外直接投资中所发挥的作用。研究结果表明:从整体上看,"一带一路"沿线国家基础设施发展状况较好,可以有效促进中国企业对外直接投资,但这种促进效应在一定程度上受限于门槛值。低基础设施发展水平地区对我国企业对外直接投资增长的贡献度达2. 658%,而高基础设施发展水平地区的贡献度仅为1. 967%。此外,东道国的经济发展水平和对外开放程度对我国企业对外直接投资有着显著的正向作用,自然资源丰裕程度与对外直接投资无显著关系。
