Dispatchable Capability of Aggregated Electric Vehicle Charging in Distribution Systems

This paper introduces a method for modeling the entire aggregated electric vehicle(EV)charging process and analyzing its dispatchable capabilities.The methodology involves developing a model for aggregated EV charging at the charging station level,estimating its physical dispatchable capability,determining its economic dispatchable capability under economic incentives,modeling its participation in the grid,and investigating the effects of different scenarios and EV penetration on the aggregated load dispatch and dispatchable capability.The results indicate that using economic dispatchable capability reduces charging prices by 9.7%compared to physical dispatchable capability and 9.3%compared to disorderly charging.Additionally,the peak-to-valley difference is reduced by 64.6%when applying economic dispatchable capability with 20%EV penetration and residential base load,compared to disorderly charging.

Accountable capability improvement based on interpretable capability evaluation using belief rule base

A new approach is proposed in this study for accountable capability improvement based on interpretable capability evaluation using the belief rule base(BRB).Firstly,a capability evaluation model is constructed and optimized.Then,the key sub-capabilities are identified by quantitatively calculating the contributions made by each sub-capability to the overall capability.Finally,the overall capability is improved by optimizing the identified key sub-capabilities.The theoretical contributions of the proposed approach are as follows.(i)An interpretable capability evaluation model is constructed by employing BRB which can provide complete access to decision-makers.(ii)Key sub-capabilities are identified according to the quantitative contribution analysis results.(iii)Accountable capability improvement is carried out by only optimizing the identified key sub-capabilities.Case study results show that“Surveillance”,“Positioning”,and“Identification”are identified as key sub-capabilities with a summed contribution of 75.55%in an analytical and deducible fashion based on the interpretable capability evaluation model.As a result,the overall capability is improved by optimizing only the identified key sub-capabilities.The overall capability can be greatly improved from 59.20%to 81.80%with a minimum cost of 397.Furthermore,this paper also investigates how optimizing the BRB with more collected data would affect the evaluation results:only optimizing“Surveillance”and“Positioning”can also improve the overall capability to 81.34%with a cost of 370,which thus validates the efficiency of the proposed approach.

Optical trapping capability of tornado circular Pearcey beams

We systemically investigate optical trapping capability of a kind of tornado waves on Rayleigh particles.Such tornado waves are named as tornado circular Pearcey beams(TCPBs)and produced by combining two circular Pearcey beams with different radii.Our theoretical exploration delves into various aspects,including the propagation dynamics,energy flux,orbital angular momentum,trapping force,and torque characteristics of TCPBs.The results reveal that the orbital angular momentum,trapping force,and torque of these beams can be finely tuned through the judicious manipulation of their topological charges(l_(1)and l_(2)).Notably,we observe a precise control mechanism wherein the force diminishes with|l_(1)+l_(2)|and|l_(1)-l_(2)|,while the torque exhibits enhancement by decreasing solely with|l_(1)+l_(2)|or increasing with|l_(1)-l_(2)|.These results not only provide quantitative insights into the optical trapping performance of TCPBs but also serve as a valuable reference for the ongoing development of innovative photonic tools.

Influence of the mechanical properties of materials on the ultimate pressure-bearing capability of a pressure-preserving controller

The pressure-preserving controller is the core part of deep in-situ pressure-preserving coring(IPP-Coring) system, and its pressure-preserving capability is the key to IPP-Coring technology. To achieve a good understanding of the influence of mechanical properties of materials on the ultimate pressure-bearing capability(UPB-Capability) of the pressure-preserving controller, the IPP-Coring experimental platform was developed to test the UPB-Capability of pressure-preserving controllers of four different materials. The experimental results show that the UPB-Capability of pressure-preserving controllers with different material varies greatly. A numerical model of the pressure-preserving controller was developed to study the influences of mechanical parameters of materials on the UPB-Capability of the pressurepreserving controller after the accuracy of the numerical model is verified by experiments. The results indicate that the yield strength(YS) and Poisson's ratio(PR) of the material have little effect on the UPB-Capability of the pressure-preserving controller, whereas the elastic modulus(EM) of the material has a significant effect. A generalized model of the UPB-Capability of the pressure-preserving controller is developed to reveal the mechanism of the influence of material properties on the UPB-Capability of the pressure-preserving controllers. Considering these results, the future optimization direction of the pressure-preserving controller and material selection scheme in practical engineering applications of the pressure-preserving controller are suggested.

基于概率的震级完备度方法评估云南地震台网的监测能力

为了科学评估云南地震台网的监测能力,分析云南地区的地震监测能力时空分布特征,采用基于概率的震级完备度(PMC)方法,利用2009-2023年云南地震台网地震目录、震相和台站信息等数据,计算了云南地震台网在云南地区的平均地震监测能力和在不同深度的监测能力,得到滇中、滇西局部地区的基于概率的完备性震级M_(P)=1.5,云南全境基本都能监测到2.5级地震。评估了研究时段内云南地震台网台站监测能力的演变,发现部分台站的监测能力持续下降。但自2018年增加20个台站后,云南2.0及2.5级地震的监测范围有一定的扩大,但微震监测能力提升不明显,可能是因为2018年以来云南一直处于小震弱活动状态。最后,对应用PMC方法规划提升台网监测能力进行了展望。

市域基层灾害治理能力评估:基于五力模型建构的分析

今天我国绝大多数的市行政区域,不但包括城区,还包括大量乡村区域,市域的概念更好地反映了这种城乡一体化的特征。从市域灾害治理的特征来看,其治理重点应在基层,而且当前的薄弱环节也主要在基层。为更好地做好我国市域基层灾害治理能力建设工作,开展市域基层灾害治理能力评估是必要的。我国市域基层灾害治理能力涉及防灾减灾救灾过程中的多种能力,主要包括领导能力、参与能力、应对能力、保障能力和科技能力。市域基层灾害治理能力评估应该对这“五力”做出全面评估。这一评估工作需要城乡各级政府及其主管部门给予一系列的政策支持,如将能力评估纳入市域基层灾害治理能力建设的工作体系,构建和完善科学的评估机制和方法,强化应急管理部门在市域基层灾害治理能力评估工作中的主导作用,加强市域基层灾害治理能力数据共享平台建设,并重视对评估结果的运用,以实现市域基层灾害治理能力评估的应用价值。

文化参与推动文化治理:社会治理现代化的新视角

文化治理能够通过文化的独特属性,渗透到社会治理的方方面面,发挥无可取代的重要作用。文化治理作为社会治理的重要取向日益受到重视,但人们对文化治理概念的理解仍存在分歧。围绕文化治理的含义和实践路径的争论,其实是对国家治理体系和治理能力现代化命题的回应。文化治理本质上是以人为主体的治理,人是文化治理中的核心主体。而在文化治理的现有实践取向中,恰恰对民众主体性的认知和发挥仍存在不足。要真正实现现代化意义上的文化治理,解决公共管理失灵的问题,不仅需要摆脱传统的文化管理方式,更需要发挥文化参与的作用。促进文化参与,将有助于提升公众在文化治理过程中的积极性,有效促进公共文化资源的匹配,从而提高文化治理水平,为国家治理体系和治理能力现代化作出更大贡献。

Capability matchmaking of semantic web services with preconditions and effects

In order to solve the problem that the current matchmaking methods for semantic web service mainly focus on the matchmaking of IO （inputs, outputs） descriptions which may result in one-sidedness, a description-logic-based IOPE （inputs, outputs, preconditions, effects） description and matchmaking method is proposed for semantic web service. The description logic concept is used to annotate service IO and the description logic assertion is employed to describe service PE（preconditions, effects）. TBox subsumption checking is used to measure the subsumption relationship between IO descriptions of service request and advertising; ABox consistency checking is used for checking the logical implication between PE descriptions of service request and advertising. Based upon the logical implication, four kinds of PE matching degrees are proposed to measure and compare the pros and cons of the results of matchmaking. They are the exact, perfect, side-effect and common match. Experiments show that the method has a higher precision rate under the same recall rate compared with the existing method.

信息流网络是一个描述作战体系从发现目标到打击目标过程中信息在平台内部和平台之间进行处理和传输的有向加权网络,研究信息流网络的抗毁性对于提高作战体系效能有着重要意义。为此,首先将作战平台所包含的搜索、跟踪、制导和攻击功能模块划分为多个节点,同时考虑节点对信息的处理能力和节点之间的信息传输能力,构建一个有向加权信息流网络,并提出改进的节点度、连边介数和网络连通性计算方法以适用于有向加权信息流网络的性能评估。然后,在传统对节点和连边的攻击方式基础上,提出针对节点和连边的蓄意软杀伤和随机软杀伤2种攻击方式。最后,对比分析了不同攻击方式对信息流网络的影响,有效模拟了有向加权信息流网络的抗毁性评估过程。
