Prototyping a software defined Utility
Energies, 2017Co-Authors: Ramon Martin De Pozuelo, Agustín Zaballos, J Navarro, Guiomar CorralAbstract:The smart grid can be seen as a hybrid system composed by many systems. From a large scale point of view, it combines the electric power system itself and a heterogeneous information and communication technology (ICT) Infrastructure. Additionally, these systems are composed by many building blocks that are designed and managed as separated systems which are hard to fully integrate between each other. Relying on the experiences arisen and the knowledge gathered from the partners during the development of the FP7 European projects INTEGRIS (intelligent electrical grid sensor communications) and FINESCE (future internet smart Utility services), this paper presents the software defined Utility (SDU) concept for the management of the smart grid and its security, which advocates for the migration of the Utility Infrastructure to software systems instead of relying on complex and rigid hardware based systems. Following this approach, SDU proposes the evolution of power systems' ICT and the usage of programmable commodity hardware, low-cost sensors, and reliable high-speed IP-based communications underneath. More concretely, this paper proposes some building blocks for the deployment of the SDU (flexible data management Infrastructure, context-aware security and web of things interface) and evaluates their functionalities and benefits for the smart grids of the future.

planning Utility Infrastructure requirements for smart cities using the integration between bim and gis
Sustainable Cities and Society, 2020Co-Authors: Mohamed Marzouk, Ahmed A OthmanAbstract:Abstract Rapid urbanization is one of the present characteristics in both developed and developing countries. It is projected that by 2050 around 68 % of the world’s population shall live in urban areas. As a result, many city development initiatives are proposed by various research centers or through academia to aid in managing the process. One of the most evolving concepts through the past two decades is Smart Cities. The concept of smart cities has been defined and formulated by many research efforts and organizations. However, most of these definitions and initiatives focus on the operation stage of the city. This paper proposes an inclusive framework for integrating Building Information Modeling (BIM) and Geographical Information System (GIS) to plan and forecast the Utility Infrastructure needs for expanding and emerging cities to highlight the concept of “smartness” during the planning stage. The considered Infrastructure needs are freshwater consumption, sewage capacity and electrical energy requirements. Firstly, the city is broken down into several districts, lands and plots. Afterwards, through the assignment of relevant land use, building type information and various other information, an interactive tool is originated to allow for the formulation of different city development schemes and the representation of their respective resulting Infrastructure needs. The framework is targeted to be flexible enough in order to be applied to any city, not just a single case as smart city solutions need to adopt to diverse cities’ needs. The proposed framework is advocated to enforce the concept of both smart and sustainable cities by taking a closer look at the city’s planning and development stages and Infrastructure requirements which shape a sizable part of the city’s performance throughout its expansion and development. It can also serve as a decision support tool for better planning and management of smart city Infrastructure requirements. Finally, a case study is represented to demonstrate the practical features of the proposed framework.

CSCS - Storage Solution of Spatial-Temporal Data for Water Monitoring Infrastructures Used in Smart Cities
2017 21st International Conference on Control Systems and Computer Science (CSCS), 2017Co-Authors: Catalin Negru, Mariana Mocanu, Valentin CristeaAbstract:Smart Cities make use of complex Utility Infrastructure systems such as water distribution. These Infrastructures have raised management costs due to improper resource utilization and maintenance or aging Infrastructure. New innovative information systems are essential to overcome these issues. Due to the continuous growth of Infrastructure systems of smart cities in scope and scale, led to the usage of spatial-temporal networks. The data generated have to be stored in an efficient and scalable way in order to be used by applications such as spatial and temporal analytics or monitoring applications.

Development of wide-band low-frequency MEMS vibration energy harvester for Utility Infrastructure core monitoring system
Symposium on Design Test Integration and Packaging of MEMS MOEMS DTIP 2017, 2017Co-Authors: Lan Zhang, Ryohei Takei, Natsumi Makimoto, Jian Lu, Takeshi Kobayashi, Toshihiro ItohAbstract:An aluminum-nitride (AlN) based energy-harvesting MEMS sensor is developed. We aimed at realizing energy-harvesting sensor with functional feature of wide-band response at low-frequency vibration domain, owing to the high-power density of vibration sources energy in a particular low frequency with several Hz deviations. By simplifying and analyzing the vibration module of the sensor structure, a special design was implemented for the first time. The given wide-band vibration energy-harvesting sensor has a disk proof mass attached to three sandwiched-AlN spring-system flexures. By MEMS techniques, the given sensors were fabricated well with the single die size of 7×7 mm and observed by the scanning electron microscopy (SEM) comprehensively. The functional feature of electrical performance of the energy-harvesting sensor was evaluated. The results demonstrated that a low resonant frequency of 57 Hz at central with wide band of 10 Hz and the voltage output of 2.5-4 mV at acceleration of 0.1-0.6g can be typically achieved. We look forward the low-frequency vibration sensor with wide-band response function can be used for many industrial and civilian applications to eliminate the restriction on power source. © 2017 IEEE.
