Smart Grid's vision is about a bold program of research, development and demonstration that charts a course towards an electricity supply network that meets the needs of Europe's future. The Smart Grid will include automation software and intelligent electronic hardware systems that control the transmission and distribution power grids. For developing distribution management and functionality of electricity market one essential objective is to make the customer active for efficient use of energy. The evolution from grid to Smart Grid is based on different functions and on the complexity of the nodes starting from interconnection between local control and central control and arriving to the Smart Grid control hub with a great level of independence and a complex functionality. The Smart Grid of the future will act much more like an interactive web, or “energy Internet,” with two-way communication, multi-directional power flow, distributed intelligence including close-loop control, stability and balance performed on site and optimization at its core. The paper presents the authors view about Smart Grid state of the art and point out the stage in standardization and practice. The contribution is on defining the functions performed by each development stage of equipment: bridge, gateway, node and control hub, the control hub architecture and the demonstrator for the gateway and protocol converter.
智能电网的愿景是一个大胆的研究、开发和示范项目,为满足欧洲未来需求的电力供应网络指明了方向。智能电网将包括控制输配电电网的自动化软件和智能电子硬件系统。为了发展配电管理和电力市场的功能,一个重要的目标是使客户积极有效地利用能源。从局部控制和中央控制之间的互联,到具有高度独立性和复杂功能的智能电网控制枢纽,电网向智能电网的演变是基于不同的功能和节点的复杂性。未来的智能电网将更像一个交互式网络或“能源互联网”,具有双向通信、多向潮流、分布式智能(包括闭环控制)、现场执行的稳定性和平衡以及核心优化。本文介绍了作者对智能电网发展现状的看法,指出了智能电网在标准化和实践方面所处的阶段。其贡献在于定义了设备的每个开发阶段所执行的功能:桥接器、网关、节点和控制集线器、控制集线器体系结构以及网关和协议转换器的演示。

This paper proposes a modern approach for the methodology that supports the measure the audience for outdoor poster advertising. The classic approach of conducting complex, limited and expensive studies about human daily routes, related just to a limited type of advertising poster may be enriched using the data that resides in the monitoring infrastructure of the cellular telecom operators over digital maps. Well segmented, this kind of data may reveal important features of the population activity at a large scale. Finally, the fine tuning options in analyzing this kind of data are discussed for future improvements.

The modeling, identification and control of distributed parameters systems, represent one of the important directions of theoretical and practical research, due to the large class of applications in which they can be involved[3-14, 33-37]. This paper proposes, an identification solution for a system with distributed parameters, represented by a heat exchanger with encasing, using open-loop identification techniques, based on whitening of the prediction error: Recursive Least Square(RLS), Extended Least Square (ELS), Recursive Maximum Likelihood (RML) and Generalized Least Square (GLS)[1,15,16,17,18]. By the discretization of the analytical model of the plant, the open-loop identification techniques, are tested for all the possible amplification gains and an optimal model with minimal order is chosen in order to chose a simple control solution.
分布式参数系统的建模、识别和控制是理论和实践研究的重要方向之一,因为它们可以涉及大量的应用[3- 14,33 -37]。本文提出了一种基于预测误差白化的开环辨识方法,针对以带壳换热器为代表的分布式参数系统:递推最小二乘(RLS)、扩展最小二乘(ELS)、递推最大似然(RML)和广义最小二乘(GLS)[1,15,16,17,18]。通过对分析模型的离散化,对开环辨识技术进行了所有可能的放大增益测试,并选择了最小阶数的最优模型,以便选择简单的控制解。

For the attractor determination, we propose in this paper a new approach based on the definition of a comparison system by special description of the linearized model of the process around an operating state which correspond to a diagonalization or if it is not possible to the description with a matrix on the arrow form, and the use of aggregation techniques. As an illustration, this approach is applied with success for the case of a third order non linear system.

Intrusions detections systems from point of view of security policy are a second line of defense; they have a supervisory role to observe the activities of our network or hosts to identify attacks in real time. In our days, electronics attacks can cause a very destructive damage for nations which make necessary the use of completed security policy to minimize the potential threats. IDS it is a very important element to resist against this vulnerability, in our works, we use a wired data base Knowledge Discovery Data Mining (KDD) CUP 99 and a Data Mining Tools Waikato Environment for Knowledge Analysis (WEKA) to combine the advantages of an intrusion detection algorithm (PART) and two techniques of Dimensionality Reduction(best first search and genetic search), to evaluate our works, we applied the proposed combined technique, and we check the results by using a several evaluations parameters. The results show that a very high detection rate for certain attacks types and highest sensitivities with the hybrid dimensionality reduction method.
从安全策略的角度来看,入侵检测系统是第二道防线;他们有一个监督的角色,观察我们的网络或主机的活动,实时识别攻击。在我们这个时代,电子攻击可以对国家造成非常破坏性的破坏,因此有必要使用完整的安全政策来最大限度地减少潜在的威胁。在我们的工作中,我们使用有线数据库知识发现数据挖掘(KDD) CUP 99和数据挖掘工具怀卡托知识分析环境(WEKA),结合入侵检测算法(PART)和两种降维技术(最佳第一搜索和遗传搜索)的优点,对我们的工作进行了评估,我们应用了提出的组合技术。我们通过使用几个评估参数来检查结果。结果表明,混合降维方法对某些攻击类型具有很高的检测率和较高的灵敏度。

The objective of this paper is to design a real-time control solution for chemical processes, namely the ethylene reactor, the key-installation in the petrochemical industry. The controller used is lag or lead controller, a simple yet suitable control tool. This article deals with the problem of finding all first order controllers that stabilize a given LTI continuous time or discrete time plant and attain various performance specifications. The main tool for the controller design is Neimarks D-decomposition, which was originally introduced in 1949 in the Russian control literature. The process data have been measured from an assembly of pyrolysis reactors on the petrochemical platform from Pitesti, Romania.

Liapunov functionals for systems with time delay and propagation 具有时滞和传播系统的Liapunov泛函
Pub Date : 2013-08-01 DOI: 10.1109/IcConSCS.2013.6632043
V. Răsvan
Starting from some recently analyzed controlled models with propagation i.e. described by hyperbolic partial differential equations, it is shown that a Liapunov functional may be attached in a natural way by using development of the energy integral. As known from the general theory of the hyperbolic partial differential equations, the energy integral is a useful tool for obtaining uniqueness theorems. On the other hand, existence theorems may be obtained either starting from difference schemes (the approach of S.K. Godunov) but also by associating some functional differential equations (the approach of A.D. Myshkis, K.L. Cooke and their followers). Due to the one to one correspondence between the two mathematical objects, the counterpart of the Liapunov functional deduced from the energy integral is obtained for the functional differential equations. Using these mathematical tools some process applications are discussed: flexible beam (manipulator), flexible overhead crane and to applications of controlling the oil drilling plants. The outcome of the analysis is given by control structures and stability criteria.
从最近分析的一些用双曲型偏微分方程描述的具有传播的控制模型出发,利用能量积分的发展,证明了李雅普诺夫泛函可以自然地附加。从双曲型偏微分方程的一般理论可知,能量积分是获得唯一性定理的有用工具。另一方面,存在性定理既可以从不同的格式出发得到(S.K. Godunov的方法),也可以通过关联一些泛函微分方程得到(A.D. Myshkis, K.L. Cooke及其追随者的方法)。由于两个数学对象之间的一一对应关系,对泛函微分方程得到了由能量积分推导出的对应的李雅普诺夫泛函。利用这些数学工具讨论了柔性梁(机械手)、柔性桥式起重机以及在石油钻采设备控制中的应用。通过控制结构和稳定性判据给出了分析结果。

A container terminal is a complex set of logistics systems with dynamic and random interactions. Information related to the container flow is often uncertain. This modification is due to inaccuracies in the arrival, departure dates of ships and arrival times of customers' trucks. Indeed, the container storage problem becomes a dynamic problem which was the subject of this work. In this paper, a heuristic method for re-marhaling outbound and inbound containers is presented. With this method, we can overcome the uncertainties of departure, arrival time of container and improve the container storage planning. This problem is studied with different container types (regular, open side, open top, tank, empty, refrigerated). The objective is to find an optimal container storage plan which respects the departure dates of container and minimize their re-handling operations at their departure time. Some experimental results are presented and discussed to verify the performance of the proposed approach.
集装箱码头是一个复杂的物流系统集合,具有动态和随机的相互作用。与容器流相关的信息通常是不确定的。此修改是由于船舶到达,离开日期和客户卡车到达时间不准确。实际上,集装箱存储问题成为了一个动态问题,这也是本研究的主题。本文提出了一种启发式的出站和入站集装箱重新编组的方法。该方法可以克服集装箱离港、到港时间的不确定性,改进集装箱的仓储规划。研究了不同的集装箱类型(常规、开边、开顶、罐式、空罐、冷藏)。目标是找到一个最优的集装箱存储计划,该计划尊重集装箱的离港日期,并最大限度地减少集装箱在离港时间的再装卸作业。给出了一些实验结果,并对其进行了讨论,以验证该方法的性能。

Indeed, the container storage problem becomes a dynamic problem which was the subject of this work. In this paper, a heuristic method for re-marhaling outbound and inbound containers is presented. With this method, we can overcome the uncertainties of departure, arrival time of container and improve the container storage planning. This problem is studied with different container types (regular, open side, open top, tank, empty, refrigerated). The objective is to find an optimal container storage plan which respects the departure dates of container and minimize their re-handling operations at their departure time. Some experimental results are presented and discussed to verify the performance of the proposed approach.","PeriodicalId":265358,"journal":{"name":"2nd International Conference on Systems and Computer Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120952086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
