Software toolchain to enhance the management and integration of a sustainable campus model

The aim of this article is to describe a novel ICT-centred methodology and software toolchain to enhance the management of a Smart Campus. The project will be implemented at the University of Campinas through a partnership between UNICAMP, CPFL (local Utility Distribution Company) and the University of Southern Denmark. This project was recently submitted to a strategic and priority call from the Brazilian Regulatory Agency (National Electric Energy Agency – ANEEL, acronym in Portuguese). The project integrates energy efficiency with research and development in distributed generation with an innovative IoT-based DMS energy management tool. These actions comply with the ISCN/GULF Sustainable Campus Chapter policies, signed by UNICAMP a few years ago. This paper is important because it will result in a replicable model for sustainable campuses, with a detailed step-by-step procedure covering local mini-grid EMS, IoT DMS, Mobility, real-time retrofitted efficiency and institutional energy governance.

Power Quality Improvement in Distribution Network using D-STATCOM with Battery Energy Storage System

End-user equipment fails or malfunctions because to power quality issues. Outages and service interruptions affect utility distribution networks, sensitive industrial loads, and important commercial operations, resulting in considerable financial losses for everybody involved. With the restructuring of power networks and the transition towards distributed and scattered generation, the issue of power quality will take on new dimensions. Take positive efforts in this area in developing countries like India, where the volatility in power frequency and many other variables of power quality are serious concerns. As a result of this study, measures that can improve the quality of power are advised. Three-stage control transmission framework with wide compensation range was proposed for Hybrid Static Synchronous Compensator (half and half D-STATCOM) by this technology. Due to these distinct properties, the cost of the framework can be drastically reduced. The circuit design of mixed D-STATCOM is provided first in this proposal. Its V–I trademark is then dissected, studied, and compared to D-STATCOM, which is more common. Finally, a parameter configuration for framework is provided, taking into account the range in which the compensating power is available and avoiding the potential reverberation issue. As a result of this, a control methodology is proposed for half-and-half D-STATCOM to allow operation under diverse voltage and current situations, such as unequal current flow, a voltage plunge, and a voltage shortfall As a final step, a reenactment and test results are provided to verify the planned half breed D-large STATCOM's pay range and high level of performance.

Forensic Identification and Root Causes of Hot Socket Problems Found in Electrical Meters

Electric meters play a critical role in electric utility distribution systems, especially for residential customers. Because it occurs so infrequently, forensic engineers may not recognize a dangerous condition within these meters known as a “hot socket.” This condition exists where the meter blades make insufficient electrical contact with the socket jaws. This paper reviews methods for forensically examining, diagnosing, and explaining the hot socket phenomenon while exploring smart meters’ incident trends.

Smart Metering in Infrastructure-Less Communication Environments and Applicability of LoRa Technology

Advanced-Metering-Infrastructure (AMI) is an integral part of Smart-Grids (SGs). It enables accurate consumer billing in presence of dynamic pricing, and improves efficiency and reliability of electricity distribution in presence of distributed generation. Value-added features of AMI such as diagnostics and maintenance service can identify the anomalous power consumption patterns of appliances at the end of their life cycle. Water and gas utility distribution networks in smart cities will incorporate AMI as an application of Internet-of-Things (IoT). The communication infrastructure plays a crucial role in enabling two-way communication between Smart-Meters (SMs) and the utility. AMI’s bi-directional communication facility supports precise modeling of load information and data management system facilitating demand-response applications to reduce energy wastage. Researchers have investigated the role of wireless technologies in Home-Area-Networks (HANs), Neighborhood-Area-Networks (NANs) and Wide-Area-Networks (WANs) in AMI. The arrival of new Low-Power-Wide-Area-Networks (LPWANs) technologies has opened up new technology integration possibilities in AMI. However, it is essential to understand the AMI architecture, envisioned application types, network requirements, features and limitations of existing technologies to determine a technology’s integration suitability in an application for smart metering technology. This chapter discusses LoRa for smart metering in infrastructure-less environments and the possible use of our multi-hop routing scheme.
