A three-dimensional(3D) embedded Eulerian-Lagrangian method is proposed to simulate the 3D fluid-structure interaction(FSI) problems subjected to explosion and impact loading. This method achieves a high-quality calculation of fluid and structure deformation by adding Lagrangian particles to Eulerian grids. The overall computational domain is solved by the Eulerian method, and the Lagrangian particles with specified volume and influence domains are used to track structural deformations. The bidirectional mapping of physical quantities is achieved using the weighted average of the influence domain, which are based on the topological relationship between Eulerian grids and Lagrangian particles. Then, the data dependence solution and parallel algorithm realization are presented for the large-scale numerical calculations of explosion and impact problems. Additionally, the corresponding parallel program is developed based on the message passing interface(MPI) standard, and the parallel efficiency of parallel hydrocode are tested. The numerical results of typical explosion and impact problems are compared with corresponding experimental data to verify the effectiveness of the method. These comparisons show that the embedded EulerianLagrangian method successfully combine the advantages of both the Eulerian and Lagrangian methods to efficiently calculate the processes of large deformation and dynamic damage to the materials. The results presented in this work provide a useful reference point for further research on explosion and impact problems.

This paper investigates an optimal day-ahead dynamic pricing problem in an electricity market with one electricity retailer and multiple customers. The main objective of this paper is to support the retailer to make the best day-ahead dynamic pricing decision, which maximizes its profit under the realistic assumption that mixed types of customers coexist in the electricity market where some customers have installed smart meters with the embedded home energy management system in their home whereas other customers have not installed smart meters. To this end, we propose a hybrid demand modelling framework which firstly uses an optimal energy management algorithm with bill minimization to model the behavior of customers with smart meters and secondly use a data-driven demand modelling method to model the behavior of customers without smart meters. Such a hybrid demand model can not only schedule usages of home appliances to the interests of customers with smart meters but also be used to understand electricity usage behaviors of customers without smart meters. Based on the established hybrid demand model for all customers, a profit maximization algorithm is developed to achieve optimal prices for the retailer under relevant market constraints. Under the condition of no growth of the revenue(i.e. no increase of total bill from all customers), simulation results indicate our optimization algorithm can improve the profit for around 5% on average.

针对现有的人工智能生成纹理和基于样图的纹理合成中存在的不可控、缺乏灵活性、低实时性等问题,运用过程纹理生成技术,提出一种基于柏林噪声和分形布朗运动的纹理生成算法,用于合成真实木制纹理特征。该算法首先将待生成的纹理空间划分为规则且均匀的网格点,同时在每个网格顶点处随机生成一个梯度向量,然后使用三线性插值方法对网格点上的梯度向量进行插值运算,同时将多频率、多振幅的噪声纹通过分形算法加权叠加处理,生成一个平滑的纹理图案,在此基础上对纹理进行缩放、扭曲、添加木眼来模拟真实的纹理结构。实验证明该算法能真实地模拟木制纹理的特征,且具有实时、高效、可定制性强等优点,在游戏、建模、虚拟现实等领域具有广泛的应用价值。

The evaluation problem with three-parameter interval grey number (T-PIGN) widely exists in real world. To select effective evaluation indicators of the problem, this paper puts forward evaluation index system selection principle of T-PIGN based on distance entropy model, and gives out evaluation index system selection judgment criterion of T-PIGN. Furthermore, for the redundancy of evaluation index system with T-PIGN, a selection method of evaluation index system with T-PIGN is proposed. Finally, the applicability of the proposed method is verified by concrete examples.

构建高比例新能源的新型电力系统指明了双碳背景下我国电力转型发展的方向。然而,由于新能源成本和出力特性与传统电源有显著差别,基于火电为主体的电力系统设计的现货市场机制不再适应新型电力系统的发展要求。为此,提出了新能源报价新机制,新能源每个时段申报一条先降后升的U型功率量价曲线,能够充分体现新能源边际成本为0、平均成本递减的成本特性和波动的出力特性,并相应提出了适应新型电力系统的现货市场和火电容量市场耦合机制。然而,这一报价模式将使得市场出清模型变为非凸函数,为此,提出了基于非凸报价的现货市场出清模型,引入一系列0-1变量,并通过不同报价段之间的耦合关系,将其转化为一个可求解的混合整数规划模型。算例验证了所提机制和模型的有效性。

新型电力系统迫切需要发展各种灵活性调节资源,必须要为灵活性调节资源设计合理的市场机制。但储能、调节式水电站等电量约束型机组的成本特性与传统电源有显著差别,基于火电为主体的电力系统设计的现货市场机制不适应电量约束型机组的特点。为此,分析了电量约束型机组的特性差异,发现其稀缺资源由电力转为电量,其成本与电量而非出力水平相关,进而论证了针对电量约束型机组特点、构建全新报价机制的必要性。在此基础上,提出了电量约束型机组在现货市场的报价机制,由申报功率量价曲线变为申报电量量价曲线,设计了考虑电量约束型机组的新型电力系统现货市场出清模型。为了激励储能参与现货市场,还提出了与现货市场相耦合的储能容量机制。算例验证了所提机制和模型的有效性。

“一带一路”倡议对中国制造业资源错配的影响

第43届中国控制会议

Short-term load forecasting is critical in energy management and grid operations. Traditional statistical learning methods lack fitting capability, and recent deep learning-based time series forecasting methods suffer from poor generalization. In this study, an ensemble learning algorithm is proposed based on the additive attention mechanism, seamlessly integrating the LSTM algorithm and the Prophet algorithm. Comparatively experimental results demonstrate that the proposed method reasonably allocates dynamic weights to the two models. Its predictive performance exhibits a substantial improvement over individual algorithms, and the ensemble algorithms with static weights. Furthermore, it also outperforms approaches employing Support Vector Regression, Ridge Regression, Extreme Gradient Boosting Regressor and Artificial Neural Network as ensemble learning algorithms.
