This paper presents a planning and real-time pricing approach for EV charging stations(CSs).The approach takes the form of a bi-level model to fully consider the interest of both the government and EV charging station operators in the planning *** the perspective of maximizing social welfare,the government acts as the decision-maker of the upper level that optimizes the charging price matrix,and uses it as a transfer variable to indirectly influence the decisions of the lower level *** each operator at the lower level determines their scale according to the goal of maximizing their own revenue,and feeds the scale matrix back to the upper level.A Logit model is applied to predict the drivers’preference when selecting a ***,an improved particle swarm optimization(PSO)with the utilization of a penalty function is introduced to solve the nonlinear nonconvex bi-level *** paper applies the proposed Bi-level planning model to a singlecenter small/medium-sized city with three scenarios to evaluate its performance,including the equipment utilization rate,payback period,traffic attraction ability,*** result verifies that the model performs very well in typical CS distribution scenarios with a reasonable station payback period(average 6.5 years),and relatively high equipment utilization rate,44.32%.

轴承是最为常见且重要的机械零部件之一,机械轴承的故障诊断方法一直被广泛关注和研究。近年来,越来越多的研究者利用深度学习方法对机械轴承进行故障检测与诊断,但为取得较好的轴承诊断结果,提出的复合诊断模型往往过于复杂,表现为多层次、多步骤、多算法集成。这导致泛化能力欠佳,只对特定场景下的轴承故障诊断有效,且计算量大,实时性欠佳。故提出一种基于长短时记忆网络的端到端故障诊断模型e2e-LSTM,可以直接利用时域振动信号对轴承的运行状态进行诊断。该模型包含3个LSTM层、2个全连接层、1个softmax层。实验结果表明,该模型能够以端到端模式一次性诊断多种轴承故障,并识别故障尺寸,即使在不同场景下,对轴承故障和尺寸的识别率仍然可以接近100%。

Addressing the complexity and isolation of the blast furnace, field engineers generally operate the system according to their former experience. While stability and safety are the first priority, it is natural to see extra consumption of ores and *** the recent years, researchers have been searching for the optimal operation point within the blast furnace by mathematical methods that include mechanism and data-driven modeling. The reported models have seldom succeeded in offering proper operation parameters to optimize several goals at the same time, as the factors of the blast furnace are highly correlative, which cannot be analyzed separately. In order to get the conflicting targets such as the lowest production cost and coke ratio as well as the highest iron quality, a multi-objective optimization model for the blast furnace based on BP neural network and genetic algorithm is proposed. The model is basically constructed on two theories. One is the BP neural network which can provide a mapping rule for multiple inputs and multiple outputs, the other is the genetic algorithm whose core contents are NSGA-Ⅱ algorithm and Pareto optimality that are fit for the multi-objective optimization goal. By optimizing the blast furnace system with this model, the plant is feasible to keep the iron making process efficient and stable simultaneously.
