The urban population growth and rapid urbanization are the key issues many of the European cities are currently dealing with. Vienna, as the one of the leading cities, embodies the smart cities goals and values. The new Smart City Wien Framework Strategy is more than a technological approach, furthermore, it emphasises importance of the social innovation. Nevertheless, the strategy lacks concrete goals for academic research and smart cities integration into educational programs. Little to no academic research discusses smart cities oriented study programs. This paper aims to close existing gap and proposes exemplary practical approach to integrate smart cities concepts at the academic level. Starting with the basic evaluation of the existing smart cities relevant study programs in the European area, we elaborate three interacting tracks for implementation: educational Web platform, postgraduate program and cross-departmental study programs including student projects. A practical, professional field-oriented and diversity-fair approach is chosen. The paper describes the status quo of the implementation process and in particular a cross-departmental study program. This exemplary implementation concept of smart cities may serve as a basis for universities with practice-oriented education to utilize own smart cities related studies.
城市人口增长和快速城市化是当前许多欧洲城市面临的关键问题。维也纳作为世界领先的城市之一,体现了智慧城市的目标和价值观。新的智慧城市维也纳框架战略不仅仅是一种技术方法,而且它强调了社会创新的重要性。然而,该战略缺乏学术研究和智慧城市融入教育项目的具体目标。几乎没有学术研究讨论智慧城市导向的学习项目。本文旨在缩小现有差距,并提出在学术层面整合智慧城市概念的示范性实践方法。从对欧洲地区现有智慧城市相关研究项目的基本评估开始,我们阐述了三个相互作用的实施轨道:教育网络平台、研究生项目和包括学生项目在内的跨部门研究项目。选择了一种实用的、专业的、面向领域的、多样性公平的方法。本文描述了实施过程的现状,特别是一个跨部门的研究计划。这一智慧城市的示范性实施理念,可以作为实践型教育高校利用自身智慧城市相关研究的基础。

The main goal of smart cities is to improve the traditional services that are provided to the citizens and also create new and more challenging ones. This vision aims not only to citizens' prosperity, but also to economic progress and sustainability of the city. It is feasible to achieve this goal through the use of technologies and architectures which purpose is to integrate the various elements of the city and help them interact in an effective manner. In this paper, we discuss the key technologies and architectures that have already been proposed in the literature in order to find the appropriate ones to be implemented for the development of smart cities.
智慧城市的主要目标是改善为市民提供的传统服务,并创造新的更具挑战性的服务。这一愿景不仅是为了市民的繁荣,也是为了城市的经济发展和可持续发展。通过使用技术和建筑来实现这一目标是可行的,其目的是整合城市的各种元素,并帮助它们以有效的方式相互作用。在本文中,我们讨论了文献中已经提出的关键技术和架构,以便找到适合智慧城市发展的技术和架构。

Smart grid is the next generation of electricity production, transmission and distribution system. This is possible through an overlayed communication layer with the power delivery layer. Due to this communication layer smart grids produce enormous amounts of data. This data may be analyzed for improving the quality of service of smart grids. However, handling such enormous amount of data is a challenge. LZMA and BZIP2 are two industrial strength compression techniques. In this paper we present an enhanced version of these two schemes specifically targeted to smart grid data through a pre-processing step. Our results show that while the original LZMA is able to compress the data size to around 80% our enhanced scheme using the preprocessing is able to reduce the size of the smart grid data to 98% on average.
智能电网是下一代电力生产、输配电系统。这可以通过与电力传输层叠加的通信层来实现。由于这个通信层,智能电网产生了大量的数据。这些数据可以用于分析,以提高智能电网的服务质量。然而,处理如此庞大的数据是一个挑战。LZMA和BZIP2是两种工业强度压缩技术。在本文中,我们提出了这两种方案的增强版本,通过预处理步骤专门针对智能电网数据。我们的结果表明,虽然原始的LZMA能够将数据大小压缩到80%左右,但我们使用预处理的增强方案能够将智能电网数据的大小平均减少到98%。

In the smart grid and smart city context, the energy end-user plays an active role in the operation of the power system. The rapid penetration of Renewable Energy Sources (RES) and Distributed Energy Resources (DER) requires a higher degree of flexibility on the demand side. As commercial and Industrial buildings (C&I) buildings represent a substantial aggregation of loads, the intertwined operation of the electric distribution network and the built environment is to large extent responsible for achieving energy efficiency and sustain-ability targets. However, the primary purpose of buildings is not grid support but rather ensuring the comfort and safety of its occupants. Therefore, the comfort level needs to be included as a constraint when assessing the flexibility potential of the built environment. This paper proposes a decentralized method for flexibility allocation among a set of buildings. The method uses concepts from non-cooperative game theory. Finally, two case of study are used to evaluate the performance of the decentralized algorithm, and compare it against a centralized option. It is shown that flexibility requests from the grid operator can be met without deteriorating the comfort levels.
在智能电网和智慧城市背景下,能源终端用户在电力系统的运行中发挥着积极的作用。可再生能源(RES)和分布式能源(DER)的快速渗透要求需求侧具有更高程度的灵活性。由于商业和工业建筑(C&I)代表了大量负载的聚集,配电网络和建筑环境的相互交织运行在很大程度上负责实现能源效率和可持续发展目标。然而,建筑的主要目的不是支撑网格,而是确保居住者的舒适和安全。因此,在评估建筑环境的灵活性潜力时,舒适度需要作为一个约束因素。本文提出了一种分散的建筑柔性分配方法。该方法使用了非合作博弈论的概念。最后,用两个研究案例来评估分散式算法的性能,并将其与集中式算法进行比较。结果表明,在不降低电网舒适度的前提下,可以满足电网运营商的灵活性要求。

This paper introduces a way to verify a microscopic pedestrian simulator. The microscopic pedestrian simulator tested in this paper is developed by our group, which can be used to guide the crowd evacuation and prepare respond plans for emergent situations as reference to city council and law enforcement agency. It is important that the simulation results reveal the true behavior of pedestrian, for certain precaution actions can be taken in order to guarantee the safety of the crowd. Therefore, the simulator has to been tested and verified using different test scenarios. In this paper, we documented the performance of our simulator tested with all 14 scenarios proposed by the RiMEA (Richtlinie für Mikroskopische Entfluchtungs-Analysen) guideline. The test results show that our simulator passes all the tests. Moreover, our pedestrian simulator constantly improves its performance by cooperating with construction companies and government departments running on-site tests with first-hand data. Now it covers emergency scenarios such as fire / smoke and floods.
本文介绍了一种验证微型行人模拟器的方法。本文所测试的微型行人模拟器是我们小组开发的,可以作为市议会和执法机构的参考,用于指导人群疏散和制定紧急情况的应对方案。重要的是,仿真结果揭示了行人的真实行为,以便采取一定的预防措施,以保证人群的安全。因此,必须使用不同的测试场景对模拟器进行测试和验证。在本文中,我们记录了我们的模拟器在RiMEA (Richtlinie f r Mikroskopische entfluchtts - analysen)指南中提出的所有14种场景下测试的性能。测试结果表明,我们的模拟器通过了所有的测试。此外,我们的行人模拟器通过与建筑公司和政府部门合作,利用第一手数据进行现场测试,不断提高其性能。现在它涵盖了火灾/烟雾和洪水等紧急情况。

Heterogeneous smart grid systems operate with different and incompatible protocols. MIRABEL and Open-ADR are prominent examples, providing intelligent demand respond functionalities. In principle of operation as in complexity, both protocols differ significantly, which results in a lack of inter-connectivity among themselves. Connecting these commonly used standards makes it possible to benefit from different protocol advantages and prevents from reconstructing whole smart grid systems for consolidation. Furthermore, it holds potentials for interoperability of individually produced smart grid components. This work contributes a conceptual mapping model between OpenADR and MIRABEL on the basis of a detailed protocol analysis, as well as an initial implementation.
异构智能电网系统采用不同且不兼容的协议运行。MIRABEL和Open-ADR是突出的例子,提供智能需求响应功能。在操作原理和复杂性上,两种协议差异很大,这导致它们之间缺乏互连性。将这些常用标准连接起来,可以从不同的协议优势中获益,并防止为了整合而重新构建整个智能电网系统。此外,它还具有实现单独生产的智能电网组件互操作性的潜力。这项工作在详细的协议分析和初始实现的基础上,提供了OpenADR和MIRABEL之间的概念映射模型。

This work aims at systematically characterizing urban mobility. There are several possible approaches to the problem but this work focus on reducing commuting times and emissions using the current infrastructures and without increasing the cost to the end user and doing so in an effective and sustainable way. A set of pairs of destinations and origins was chosen to represent usual commutes and cover a significant area of a city. These locations were connected by car, motorcycle, public transportation, cycling and walking. The routes were performed in both directions at three different times of day which allowed for a better understanding of daily traffic variations. For each route and for each mode of transportation the route and time taken were collected and the emissions and cost were estimated. The data was treated to adjust the route and gradient difference between the collected data and actual roads. Measurements and estimates were compared and averaged for all the routes and for each means of transportation providing an overall view of the commutes. The different means of transportation were compared and the limit to which one mode has the advantage over another was evaluated, this advantage is however dependent on the chosen route.
这项工作旨在系统地描述城市流动性。有几种可能的方法来解决这个问题,但这项工作的重点是利用现有的基础设施,在不增加最终用户成本的情况下,以有效和可持续的方式减少通勤时间和排放。选择了一组对的目的地和起点来代表通常的通勤,并覆盖城市的重要区域。这些地点通过汽车、摩托车、公共交通、自行车和步行连接起来。这些路线在一天的三个不同时间向两个方向行驶,以便更好地了解每天的交通变化。对于每条路线和每一种运输方式,收集了路线和时间,并估计了排放和成本。对数据进行处理,调整采集数据与实际道路之间的路线和坡度差异。对所有路线和每种交通工具的测量值和估计值进行了比较和平均,从而提供了通勤的总体视图。对不同的运输方式进行了比较,并对一种方式优于另一种方式的限制进行了评估,然而,这种优势取决于所选择的路线。

Generating the power necessary to run our future cities is one of the major concerns for scientists and policy makers alike. The increasing global energy demands with simultaneously decreasing fossil energy sources will drastically affect future energy prices. Strategies are already being implemented to develop solutions for the generation and efficient usage of energy at different levels. Involving citizens in the efficient planning and usage of power is a key. In this paper, we propose a game theory based power sharing mechanism between end-users in smart grids. We consider that citizens can produce some amount of electric power obtained from on-site renewable sources rather than just purchasing their whole demands from the grid. Simulation results show that consumers can achieve considerable cost savings if they adopt the proposed scheme. It is also noticed that the more the consumers cooperate, the higher the percentage of cost savings is.
为我们未来的城市提供必要的电力是科学家和政策制定者所关心的主要问题之一。全球能源需求的增加与化石能源的减少将极大地影响未来的能源价格。目前正在执行各种战略,为不同层次的能源产生和有效使用制定解决办法。让公民参与有效规划和使用电力是关键。本文提出了一种基于博弈论的智能电网用户间电力共享机制。我们认为市民可以从现场可再生能源中获得一定数量的电力,而不是仅仅从电网购买他们的全部需求。仿真结果表明,采用该方案可以为用户节省大量的成本。我们还注意到,消费者合作越多,节省的成本百分比就越高。

The Power grid evolves, but its structure presents several gaps with the new numerical technologies, renewable energies and electric vehicles. The literature introduces the concept of Smart Grid, a system which takes into account the behaviour and the action of its agents. Studying the smart grid through modelling and simulation provides us with valuable results which cannot be obtained in the real world due to time and cost related constraints. Nevertheless, due to the complexity of the smart grid, achieving global optimization is not an easy task. In this paper, we propose a complex system approach to the smart grid modelling, accentuating on the representation of the structure. Thanks to this combination, the optimization can be achieved on a dynamic graph taking into account changes and network errors over time, with the ability to detect them.
电网不断发展,但其结构与新的数字技术、可再生能源和电动汽车存在一些差距。文献介绍了智能电网的概念,这是一个考虑到其代理的行为和行动的系统。通过建模和仿真来研究智能电网,为我们提供了有价值的结果,而这些结果在现实世界中由于时间和成本的限制而无法获得。然而,由于智能电网的复杂性,实现全局优化并非易事。在本文中,我们提出了一种复杂系统的智能电网建模方法,着重于结构的表示。由于这种组合,可以在考虑变化和网络错误的动态图上实现优化,并能够检测到它们。

Thanks to this combination, the optimization can be achieved on a dynamic graph taking into account changes and network errors over time, with the ability to detect them.","PeriodicalId":408526,"journal":{"name":"2015 International Conference on Smart Cities and Green ICT Systems (SMARTGREENS)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134195914","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}

The transport sector is constantly growing as well as its complexity and energy consumption. One way to reduce the involvement and the volume of data to evaluate and monitor the energy efficiency of the sector for cities authorities is by using Key Performance Indicators (KPIs). This paper describes a set of KPIs to measure and track energy efficiency in the transport sector. The KPIs that are summarized in this paper were identified based on a literature review of mobility projects/strategies/policies that had been implemented in cities around the world. Future applications, which are presented at the end of this article, will give a better understanding of the systems and its components.
交通运输部门在不断增长,其复杂性和能源消耗也在不断增加。为城市当局减少参与和评估和监测该部门能源效率的数据量的一种方法是使用关键绩效指标。本文描述了一套衡量和跟踪运输部门能源效率的关键绩效指标。本文总结的关键绩效指标是根据对世界各地城市实施的交通项目/战略/政策的文献综述确定的。本文最后介绍的未来应用程序将更好地理解系统及其组件。
