MERGE – Microgrids for Efficient, Reliable and Greener Energy

Prof. Dr. Luiz Carlos Pereira da Silva

University of Campinas, UNICAMP

Microgrids are a strong alternative for the evolution of traditional electrical systems towards a more flexible and resilient network. Although microgrids are often deployed in remote communities and military bases to provide energy independence and continuity, these benefits can easily be extended to local communities, university campuses, and even manufacturing centers. In the Brazilian case, these benefits are even more relevant, as electricity consumers suffer interruptions in supply for an average of 14.35 hours per year (2017). These supply interruptions are estimated to have an impact of U$ 84,5 million. Microgrids are a clear alternative to combat interruption and have the potential to improve other aspects of the electricity supply. A microgrid, properly planned and operated, can reduce losses, increase the efficiency of renewable energy and create new business models. It is estimated that around U$ 570 million will flow into the microgrids market in Brazil by 2025, and spending on global implementation is expected to reach almost US$ 112 billion by 2026. The different technologies related to distributed renewable sources, energy storage, demand management, smart metering and sensing, electric vehicles, advanced communication systems, management systems, and optimization of distributed resources; appear independently and with different technical and commercial maturity levels. Microgrids emerge with the primary function of coordinating and merging different technologies in a single platform. As a result of this coordinated operation, operating the micro-grids in isolation from the main network is possible since the design of a micro-network already includes physical and management resources to make this operation feasible. In this context, this project seeks to develop knowledge to anticipate opportunities, support norms, suggest standards, face threats and generate added value through the study of the implementation of real applications. Microgrids will be developed, tested, and operated in both normal (connected) and emergency (island) modes. In addition, the distribution network will be integrated to increase efficiency, reliability, service quality, and energy quality. The integration will also allow reducing losses, greenhouse gas emissions, and maximizing renewable resources.

Distribution System Resilience: Modeling and Optimization

Dr. Anamika Dubey

WSU Pullman, USA

Extreme weather events threaten the power delivery infrastructure causing an extended disruption of electricity supply to the critical services. Recent fire-related damages caused by high-voltage transmission lines coupled with dry weather are costing billions of dollars annually, with the only practical solution being de-energizing the lines and disrupting the power supply to millions of customers. Most impacts are observed at the mid and low voltage distribution systems due to inadequate incorporation of resilience at the distribution level. The changing nature of the grid and extreme weather events motivate new mechanisms to manage grid operations by leveraging smart grid technologies. For example, the recent extended outage in Texas due to resource adequacy concerns from an unusual cold front motivates new operational solutions to partially support critical and non-critical services.  This tutorial will introduce the approach to model and quantify the impacts of extreme weather events on the power distribution grid and discuss planning and operational solutions to improve the distribution grid resilience. The use cases will be demonstrated using standard distribution test feeders.

Datasets and Standardized Artificial Intelligence for 5G and 6G with Applications in MIMO Beamforming, Sensing and Smart Grids

Prof. Dr. Aldebaro Klatau

UFPA, Brazil

Artificial intelligence (AI), such as machine learning (ML) methods using deep neural networks, will be increasedly used to optimize the performance of future mobile networks.
In 5G and 6G networks, AI/ML will be used together with network slicing and other techniques to support use cases with very different requirements. But AI/ML for communications has not reached the maturity observed in other areas. Different from, e.g., computer vision and speech recognition, communications heavily rely on standards (3GPP, ITU, etc.) and design and assessment methodologies for model-based algorithms. To make AI/ML for communications vigorously expand, these two aspects need to be taken in account. Therefore, this talk discusses ongoing standardization efforts to facilitate AI/ML in 5G/6G, as well as data-driven methodologies to generate realistic datasets and design ML algorithms that outperform model-based ones in rigourous benchmarks. A brief introduction to deep supervised and reinforcement learning is also provided. The talk is concluded with selected examples of AI/ML in 5G/6G for MIMO beamforming, sensing using communication systems, digital twins and smart grids.

Aldebaro Klautau received the bachelor (Universidade Federal do Pará, UFPA, 1990), M. Sc. (Universidade Federal de Santa Catarina, UFSC, 1993) and Ph. D. degrees (University of California at San Diego, UCSD, 2003) in Electrical Engineering. Since 1996, he has been with UFPA and is now full professor, the ITU Focal Point, and directs the LASSE Research Group. He was a visiting scholar at Stockholm University, UCSD and The University of Texas at Austin. He is a researcher of the Brazilian National Council of Scientific and Technological Development (CNPq) and INESC Brazil. He is also a senior member of the IEEE and of the Brazilian Telecommunications Society (SBrT). His work focuses on machine learning and signal processing for communications and embedded systems.

A Walkthrough MTC evolution toward 6G: key drivers, requirements, and use-cases

Prof. Dr. Hirley Alves

University of Oulu

Machine-type Communication (MTC) has revolutionized the wireless communications industry by shifting the focus from broadband towards the Internet of Things (IoT). Initially, within 5G, two service modes were introduced to cover a large number of use-cases: massive MTC (mMTC) and critical MTC (cMTC) (often referred to as ultra-reliable low-latency communication (URLLC)). mMTC focuses on providing connectivity to several devices that are often battery constrained with limited computational capability and heterogeneous and sporadic traffic patterns. On the other end is cMTC aimed at ultra-reliable low latency communication stringent needs on resilience and dependability. However, despite the accomplishments achieved so far with 5G, these service modes are not enough. As a result, we are experiencing the emergence of novel service classes mixing massive and critical MTC requirements with the broadband ones, creating a palette of novel services. Such services will be prominent in the next generation, 6G. Therefore, in this keynote, we will walk through the MTC (r)evolution and present key drivers, requirements, and use-cases towards 6G.

Hirley Alves (S’11–M’15) is Assistant Professor and Head of the Machine-type Wireless Communications Group at the 6G Flagship, Centre for Wireless Communications, University of Oulu. He is actively working on massive connectivity and ultra-reliable low latency communications for future wireless networks, 5GB and 6G, full-duplex communications. In addition, he leads the MTC/URLLC activities for the 6G Flagship Program. He has received several awards and has been the organizer, chair, TPC, and tutorial lecturer for several renowned international conferences. He is the General Chair of the ISWCS’2019 and the General Co-Chair of the 1st 6G Summit, Levi 2019, and ISWCS 2021.

Spectrum access evolution to enable next mobile networks generations

Dr. Fabiano Chaves

Increasing demand and use of spectrum is a trend that has been observed since the first generations of mobile networks, and their communication channels some hundreds of kilohertz-wide, up to 5G and its capability of operating with gigahertz-wide blocks of spectrum. There is no indication of a change in this trend – on the contrary, the envisaged future mobile networks and applications have as one of their enablers the use of more spectrum in a more efficient way. In this talk we will discuss ongoing and future developments in the spectrum management domain for enablement of next generations of commercial mobile networks.
