摘要：Besides grid-to-vehicle(G2 V) and vehicle-to-grid(V2 G) functions, the battery of an electric vehicle(EV) also has the specific feature of mobility. This means that EVs not only have the potential to utilize the storage of cheap electricity for use in high energy price periods, but can also transfer energy from one place to another place. Based on these special features of an EV battery, a new EV energy scheduling method has been developed and is described in this article. The approach is aimed at optimizing the utilization EV energy for EVs that are regularly used in multiple places. The objective is to minimize electricity costs from multiple meter points. This work applies real data in order to analyze the effectiveness of the method. The results show that by applying the control strategy presented in this paper at locations where the EVs are parked, the electricity cost can be reduced without shifting the demand and lowering customer's satisfaction. The effects of PV size and number of EVs on our model are also analyzed in this paper. This model has the potential to be used by energy system designers as a new perspective to determine optimal sizes of generators or storage devices in energy systems.

摘要：This paper presents the design method of hybrid drive system for the minibus with some limited conditions. The approach of design hybrid drive system is based on the dynamic modeling and simulation of the hybrid minibus with planetary gear system. The main target of the design is to obtain the optimal design with the proper hybrid drive configuration and control for a given set of design constraints. In oder to meet the design target, it's necessary to adjust some parameters such as mechanical ratios and parameters of battery pack as well as control by simulation. During simulation the transient operating process can be studied in details with the dynamic model in Matlab/Simulink. The control strategy can be optimized by running the simulation and monitoring the operation of each components: the operating area of internal combustion engine (ICE), fuel consumption (energy consumption), the power distribution, the torque and rotary speed of ICE and motor, the operating efficiency of motor, the alteration of battery state of charge (SOC), current and voltage. © by High Technology Letters Press.

摘要：氧化钨(WO_(3))是一种重要的光电化学分解水半导体,具有可见光响应好、无毒、稳定性好等优点,但低的电导率、高的起始电位以及缓慢的水氧化动力学等缺点也限制了其进一步应用。本文采用无晶种水热法在导电玻璃(FTO)上设计了一种钛掺杂的WO_(3)纳米片阵列,并研究了Ti掺杂浓度对光电化学分解水性能的影响。结果表明,在0.6 V(vs Ag/AgCl)的偏压下,Ti掺杂WO_(3)光电流密度最高,可达0.53 mA/cm^(2),比纯WO_(3)纳米片阵列的高110%。同时,Ti掺杂WO_(3)光电极的起始电位负移。X射线光电子能谱价带谱(XPS-VB)和紫外-可见吸收(UV-Vis)光谱显示,Ti掺杂WO_(3)光阳极的能带位置向上移动,导致了起始电位的负移。此外,电化学阻抗谱测试(EIS)表明,Ti掺杂WO_(3)光阳极的导电性显著增强,引起光生载流子的快速分离。研究成果有望提供一种高效、低成本光阳极的设计路线。
