Transactive Demand Response Operation at the Grid Edge using the IEEE 2030.5 Standard Article

Javad Fattahi, Mikhak Samadi, Melike Erol-Kantarci, Henry Schriemer

Engineering 2020, Volume 6, Issue 7,   Pages 801-811 doi: 10.1016/j.eng.2020.06.005

Abstract:

This paper presents a transactive demand response (TDR) scheme for a network of residential customers with generation assets that emphasizes interoperability within a transactive energy architecture. A complete laboratory-based implementation provides the first (to our knowledge) realization of a comprehensive TDR use case that is fully compliant with the Institute of Electrical and Electronics Engineers (IEEE) 2030.5 standard, which addresses interoperability within a cybersecure smart energy profile (SEP) context. Verification is provided by a full system integration with commercial hardware using IP-based (local area network (LAN) and Wi-Fi) communication protocols and transport layer security (TLS) 1.2 cryptographic protocol, and validation is provided by emulation using extensive residential smart meter data. The demand response (DR) scheme is designed to accommodate privacy concerns, allows customers to select their DR compliance level, and provides incentives to maximize their participation. The proposed TDR scheme addresses privacy through the implementation of the SEP 2.0 messaging protocol between a transactive agent (TA) and home energy management system (HEMS) agents. Customer response is handled by a multi-input multi-output (MIMO) fuzzy controller that manages negotiation between the customer agent and the TA. We take a multi-agent system approach to neighborhood coordination, with the TA servicing multiple residences on a common transformer, and use a reward mechanism to maximize customer engagement during the event-based optimization. Based on a set of smart meter data acquired over an extended time period, we engage in multiple TDR scenarios, and demonstrate with a fully-functional IEEE 2030.5-compliant implementation that our scheme can reduce network peak power consumption by 22% under realistic conditions.

Home location inference from sparse and noisy data: models and applications

Tian-ran HU,Jie-bo LUO,Henry KAUTZ,Adam SADILEK

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 5,   Pages 389-402 doi: 10.1631/FITEE.1500385

Abstract: Accurate home location is increasingly important for urban computing. Existing methods either rely on continuous (and expensive) Global Positioning System (GPS) data or suffer from poor accuracy. In particular, the sparse and noisy nature of social media data poses serious challenges in pinpointing where people live at scale. We revisit this research topic and infer home location within 100 m×100 m squares at 70% accuracy for 76% and 71% of active users in New York City and the Bay Area, respectively. To the best of our knowledge, this is the first time home location has been detected at such a fine granularity using sparse and noisy data. Since people spend a large portion of their time at home, our model enables novel applications. As an example, we focus on modeling people’s health at scale by linking their home locations with publicly available statistics, such as education disparity. Results in multiple geographic regions demonstrate both the effectiveness and added value of our home localization method and reveal insights that eluded earlier studies. In addition, we are able to discover the real buzz in the communities where people live.

Ahsan Noor Khan, Young-ok Cha, Henry Giddens, Yang Hao

Engineering 2022, Volume 11, Issue 4,   Pages 27-41 doi: 10.1016/j.eng.2021.10.019

Abstract:

Highlights Bioelectronic devices have revolutionized the course of therapeutic treatment with their ability to harness neuronal activities in the human body. Recent advances in the field of soft, stretchable and biocompatible materials have enabled the development of bioelectronics to treat wide range of chronic ailments and disorders. Such treatments involve the confluence of electronics with neuronal cells or tissues, and mostly require surgical operation to implant the bioelectronic device. For recording neural activities and programming the device non-invasively, copious amount of research is in progress to devise wireless technology enabled bioelectronics. This paper discusses the latest developments in wireless bioelectronic devices for organ specific treatments, including gastrointestinal tract monitoring, retinal prosthesis, auditory nerve and brain stimulation. Major highlights include seminal components that mediate the overall wireless operation, such antennas, rectifiers, amplifier and integrated circuits. Moreover, the constituting materials of antennas, operational frequency and their integration with other electronic components are discussed. Replete perspective on the strategies to energize bioelectronics using wireless power transfer is explained. Communication protocols for biotelemetry are also discussed.The integration of electronics and biology has spawned bioelectronics and opened exciting opportunities to fulfill the unmet needs of therapeutic treatments. Recent developments in nanoelectronics and soft and biocompatible materials have shown potential applicability to clinical practices, including physiological sensing, drug delivery, cardiovascular monitoring, and brain stimulation. To date, most bioelectronic devices require wired connections for electrical control, making their implantation complicated and inconvenient for patients. As an alternative, wireless technology is proliferating to create bioelectronics that offer noninvasive control, biotelemetry, and wireless power transfer (WPT). This review paper provides a comprehensive overview of wireless bioelectronics and ongoing developments in their applications for organ-specific treatments, including disorders and dysfunctions. The main emphasis is on delineating the key features of antennas, namely their radiation characteristics, materials, integration with rest of the electronics, and experimental setup. Although the recent progress in wireless mediated bioelectronics is expected to enhance the control of its functionalities, there are still numerous challenges that need to be addressed for commercialization, as well as to address ever-expanding evolving future therapeutic targets.

Cantonese porcelain classification and image synthesis by ensemble learning and generative adversarial network Special Feature on Intelligent Design

Steven Szu-Chi CHEN, Hui CUI, Ming-han DU, Tie-ming FU, Xiao-hong SUN, Yi JI, Henry DUH

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 12,   Pages 1632-1643 doi: 10.1631/FITEE.1900399

Abstract: Accurate recognition of modern and traditional porcelain styles is a challenging issue in Cantonese porcelain management due to the large variety and complex elements and patterns. We propose a hybrid system with porcelain style identification and image recreation modules. In the identification module, prediction of an unknown porcelain sample is obtained by logistic regression of ensembled neural networks of top-ranked design signatures, which are obtained by discriminative analysis and transformed features in principal components. The synthesis module is developed based on a conditional generative adversarial network, which enables users to provide a designed mask with porcelain elements to generate synthesized images of Cantonese porcelain. Experimental results of 603 Cantonese porcelain images demonstrate that the proposed model outperforms other methods relative to precision, recall, area under curve of receiver operating characteristic, and confusion matrix. Case studies on image creation indicate that the proposed system has the potential to engage the community in understanding Cantonese porcelain and promote this intangible cultural heritage.

An overview and recent advances in electrocatalysts for direct seawater splitting

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 6,   Pages 1408-1426 doi: 10.1007/s11705-021-2102-6

Abstract: In comparison to pure water, seawater is widely accepted as an unlimited resource. The direct seawater splitting is economical and eco-friendly, but the key challenges in seawater, especially the chlorine-related competing reactions at the anode, seriously hamper its practical application. The development of earth-abundant electrocatalysts toward direct seawater splitting has emerged as a promising strategy. Highly efficient electrocatalysts with improved selectivity and stability are of significance in preventing the interference of side reactions and resisting various impurities. This review first discusses the macroscopic understanding of direct seawater electrolysis and then focuses on the strategies for rational design of electrocatalysts toward direct seawater splitting. The perspectives of improved electrocatalysts to solve emerging challenges and further development of direct seawater splitting are also provided.
