To deal with frequent power outages in developing countries, people turn to solutions like uninterruptible power supply (UPS), which stores electric energy during normal operating hours and use it to meet energy needs during rolling blackout intervals. Locally produced UPSs of poorer power quality are widely accessible in the marketplaces, and they have a negative impact on power quality. The charging and discharging of the batteries in these UPSs generate significant amount of power losses in weak grid environments. The Smart-UPS is our proposed smart energy metering (SEM) solution for low voltage consumers that is provided by the distribution company. It does not require batteries, therefore there is no power loss or harmonic distortion due to corresponding charging and discharging. Through load flow and harmonic analysis of both traditional UPS and Smart-UPS systems on ETAP, this paper examines their impact on the harmonics and stability of the distribution grid. The simulation results demonstrate that Smart-UPS can assist fixing power quality issues in a developing country like Pakistan by providing cleaner energy than the battery-operated traditional UPSs.
为了应对发展中国家频繁的停电,人们转向不间断电源(UPS)等解决方案,UPS在正常工作时间储存电能,并在滚动停电间隔期间使用它来满足能源需求。电能质量较差的本地生产的ups在市场上广泛使用,它们对电能质量有负面影响。在弱电环境下,ups电池的充放电会产生大量的电能损耗。smart - ups是我们为配电公司提供的低压消费者提出的智能能源计量(SEM)解决方案。它不需要电池,因此不存在因相应的充放电而产生的功率损失和谐波畸变。本文通过对传统UPS系统和智能UPS系统在ETAP上的负荷潮流和谐波分析,考察了它们对配电网谐波和稳定性的影响。模拟结果表明,Smart-UPS可以通过提供比电池供电的传统ups更清洁的能源,帮助解决巴基斯坦等发展中国家的电能质量问题。

The technology and innovations introduced by information systems have revolutionized how public institutions use their infrastructures and manage their assets. Even more, the need to carry out maintenance and to guarantee adequate standards of safety, efficiency, and quality of the services provided has prompted administrations and managers to integrate, in their management plans, the use of Information Computer Technologies (ICT). They are used as a tool through which it is possible to ensure the transition between the previous management and the new needs in the context of Smart mobility and, in general, Smart City. In this sense, this paper introduces a remote monitoring system built at the port terminal of Tremestieri (located in the city of Messina, Italy) that exploits deep learning to perform an Automatic Number Plate Recognition (ANPR) of vehicles transiting the area. Using a set of cameras installed at the terminal, this system allows to compute synthetic traffic indicators (e.g., arrival distribution, travel time, platooning and queuing phenomena) that can be used to infer the traffic conditions and the overall operability of the infrastructure in a non-invasive manner, highlighting daily peak hours and trends in the use of the terminal, also achieving an estimation of congestion phases.
信息系统带来的技术和创新彻底改变了公共机构使用其基础设施和管理其资产的方式。更重要的是,由于需要进行维护和保证所提供服务的安全、效率和质量的适当标准,这促使行政当局和管理人员将信息计算机技术的使用纳入其管理计划。它们被用作一种工具,通过这种工具,可以确保在智能移动和智能城市的背景下,从以前的管理到新的需求之间的过渡。从这个意义上讲,本文介绍了一个建立在Tremestieri港口码头(位于意大利墨西拿市)的远程监控系统,该系统利用深度学习对通过该地区的车辆执行自动车牌识别(ANPR)。该系统利用安装在客运大楼的一组摄影机,计算综合交通指标(例如到达分布、行车时间、排队和排队现象),以非侵入式的方式推断交通状况和基础设施的整体可操作性,突出显示每日高峰时间和客运大楼的使用趋势,并实现对拥塞阶段的估计。

Green electrification and carbon neutrality are of critical importance for the future of the Mediterranean area (MED) because it is expected to suffer more than other areas from climate change. The path to decarbonization requires the electrification and digitalization of the power infrastructure with the deployment of innovative energy systems. Future energy solutions must be based on Renewable Energy Sources (RES) to replace the existing fossil fuel-based power generators. To increase the RES share and accelerate this transformation to a more sustainable energy future, it is required to develop decentralized systems with a high level of operational flexibility. Solar energy is abundant in the MED area, but due to its intermittent nature, solar Photovoltaics (PVs) cannot satisfy electrical energy demand as standalone systems. A possible way to increase self-sufficiency and RES share is to couple PV modules with Energy Storage Systems (ESS) and Demand Side Management (DSM). The BERLIN project has been created with the aim of materializing these targets, and to create a new paradigm under the concept of hybrid nanogrid PV-ESS-DSM systems. The current paper describes the components, configurations, and operating principles of the hybrid PV-ESS-DSM nanogrid demonstration systems that are currently under development.
绿色电气化和碳中和对地中海地区(MED)的未来至关重要,因为预计地中海地区比其他地区更容易受到气候变化的影响。脱碳之路需要电力基础设施的电气化和数字化,并部署创新的能源系统。未来的能源解决方案必须基于可再生能源(RES),以取代现有的以化石燃料为基础的发电机。为了增加可再生能源的份额并加速向更可持续的能源未来的转变,需要开发具有高度操作灵活性的分散系统。中东地区太阳能资源丰富,但由于其间歇性,太阳能光伏发电(pv)作为独立系统无法满足电力需求。增加自给自足和可再生能源共享的一种可能方法是将光伏模块与储能系统(ESS)和需求侧管理(DSM)相结合。柏林项目的目的是实现这些目标,并在混合纳米电网PV-ESS-DSM系统的概念下创建一个新的范例。本文描述了目前正在开发的混合PV-ESS-DSM纳米电网演示系统的组成、配置和工作原理。

Towards a Digital Twin for Air Quality Monitoring Networks in Smart Cities 迈向智慧城市空气质量监测网络的数字孪生

In the context of smart cities, high-resolution air quality monitoring with low-cost sensor systems has seen remarkable interest. These systems, however, need frequent recalibration to maintain metrological traceability. Air pollution models based on partial differential equations offer an arbitrary spatial and temporal resolution, but they require some experimental data as initial and boundary conditions in order to be solved. This theoretical paper makes considerations that air quality monitoring networks and air pollution models could be combined into one single measurement instrument. Not only would this allow a high resolution with a lower number of network nodes but it would also result in a simple method for recalibration, given the traceability of simulations. At the same time, the performed measurements would serve as input for the solution of the differential equations. While all necessary parts for a potential realization are available, challenges such as low data quality and computational burden have to be overcome first.
在智慧城市的背景下,低成本传感器系统的高分辨率空气质量监测引起了人们的极大兴趣。然而,这些系统需要经常重新校准以保持计量可追溯性。基于偏微分方程的空气污染模型提供了任意的空间和时间分辨率,但它们需要一些实验数据作为初始条件和边界条件才能求解。这篇理论论文考虑了空气质量监测网络和空气污染模型可以合并成一个单一的测量仪器。这不仅可以在较少的网络节点数量下实现高分辨率,而且还可以提供一种简单的重新校准方法,考虑到模拟的可追溯性。同时,所进行的测量将作为微分方程解的输入。虽然潜在实现的所有必要部分都是可用的,但必须首先克服诸如低数据质量和计算负担等挑战。

Smart city implementation, including various smart solution projects, is widely applied to solve urban problems such as traffic, environment, safety, etc. However, many smart solutions fail to solve urban problems when implemented. This study proposes a living lab approach to help achieve the goals of smart city development. Furthermore, if another living lab approach only talks about one problem, our study discusses how the living lab integrates multiple problems into one platform that evaluates and monitors the living lab. This study also introduces and discusses DDG as an area that integrates multiple services. The DDG area is a pilot project of the integrated living lab that can manage some issues such as waste, mobility, and economy in an integrated living lab platform that provides information for decision making.

In virtual worlds such as those realized through virtual reality technologies, the participants usually use the third-person perspective to see a wider area because the third-person perspective provides a variety of benefits. In this study, we propose an approach using both the first-person and third-person perspectives in real world applications, such as in smart city services, and evaluate the potential opportunities to offer more advanced digital services. We collect use cases and opinions for designing the prototype system's video presentation methods. Then, we implement prototype systems that enable the users to see from both the first-person and third-person perspectives by using webcams and a head-mounted display. Our approach makes it possible to develop new types of game-inspired smart city services that offer more opportunities through the multiple perspectives.

A novel single static-camera multiple pedestrian detection and tracking system, which could be succesfully used by the Smart City technologies, is introduced in this article. The moving person detection process is performed by applying a combination of advanced computer vision and machine learning solutions, such as Gaussian Mixture Models (GMM), Histogram of Oriented Gradients (HOG), Support Vector Machines (SVM) and Aggregate Channel Features (ACF), to each frame of the color video sequence. An instance matching-based tracking technique that uses a deep learning-based multiscale analysis of the subimages of the detected pedestrians is then proposed. Its scale-space is created by applying the numerical approximation algorithm of a well-posed nonlinear anisotropic diffusion-based model that is introduced here. The results of the pedestrian detection and tracking experiments are described in the end.

The results of the pedestrian detection and tracking experiments are described in the end.","PeriodicalId":277015,"journal":{"name":"2022 IEEE International Smart Cities Conference (ISC2)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114490832","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}

Planning mobility solutions that are tailored to the users needs, while being sustainable and energy efficient, will be crucial for the development of the Smart Cities of the future. This is especially true nowadays, given the environmental and political issues characterizing this historical time. Sharing mobility can be an asset in increasing the sustainability of daily transportation in urban areas, allowing more people to move around, while leading to energy and resource savings. At the same time, there are several barriers preventing the adoption of this mobility solution. In this work, we introduce the steps leading to the construction of the Sharing-DNA, a novel data-driven tool to understand the main levers of individual attitudes towards sharing services. By compactly embedding relevant information on the socio-economic profile and mobility preferences of potential adopters, this new tool can be of use for the design of incentive policies in the future Smart Cities. This is proven by the preliminary results obtained by exploiting the Sharing-DNA to detect clusters of sharing-oriented and less sharing-enthusiast individuals within Europe. The characteristics of these clusters allow us to shed a light on the attributes of the final users (or potential ones) of sharing services, providing a useful machinery for the design of common fostering policies.
规划适合用户需求的移动解决方案,同时保持可持续和节能,对未来智慧城市的发展至关重要。考虑到这一历史时期的环境和政治问题,这一点在今天尤其正确。共享交通可以成为提高城市地区日常交通可持续性的一项资产,允许更多的人四处走动,同时节省能源和资源。同时,还存在一些阻碍采用这种移动性解决方案的障碍。在这项工作中,我们介绍了构建共享dna的步骤,这是一种新的数据驱动工具,用于理解个人对共享服务态度的主要杠杆。通过紧凑地嵌入有关潜在采用者的社会经济状况和出行偏好的相关信息,这个新工具可以用于设计未来智慧城市的激励政策。通过利用共享dna来检测欧洲范围内以共享为导向和不那么热衷于共享的个体群,所获得的初步结果证明了这一点。这些集群的特征使我们能够阐明共享服务的最终用户(或潜在用户)的属性,为设计共同的培育政策提供有用的机制。
