Through the Grid Joint Communication and Sensing.
Abstract: Probing the environment and teleconnecting nodes in a communication network are two usage scenarios for wave-propagation signals. Historically they have been treated separately, most prominently as radio detection and ranging (radar) and radio communication in wireless systems. A new trend referred to as joint communication and sensing sees the convergence of the two functionalities. It has attracted a lot of attention in the wireless community, as it holds the promise to create new services for users of wireless communication technology. We believe that a similar amalgamation is meaningful for communication over power lines. In particular, the through-the-grid feature of power line communication (PLC) signals makes them a natural candidate for integrating infrastructure monitoring tasks into PLC networks. In this talk, we will reflect on the notion of joint communication and sensing, considering different signal classes and environments. We will then overview the use of PLC signals for sensing tasks and compare this with classical cable-health monitoring methods. We argue that sensing tasks can be formulated as function inversion problems, which are challenging to model and to solve algorithmically. This makes machine learning based methods attractive. We will present some of our recent work in this direction, and end with some thoughts for future research. We hope that this talk stimulates discussion on the topic between academic researchers, PLC equipment vendors and power utilities.

Need of communication for process data management and a possible role of powerline – challenges of broadband powerline in electricity grid.
Abstract: Climate change and the associated need to decarbonise society have an immense impact on our industry. The energy supply companies and network operators are particularly affected by this. By replacing fossil primary energy sources, we are experiencing a dramatic change in the type and location of energy generation. In addition, the need for “clean” electricity in the lower grid levels is constantly increasing. In order to meet these requirements, the need for transparency and control options in the power grids increases considerably, especially in the lower voltage levels. This transparency, which is the basis for monitoring and controlling the networks, is only possible with the appropriate communication technologies and operating models which, in addition to adequate performance, also guarantee the security and availability of the communication networks. Broadband powerline is one of these technologies. However, as with any technology that is being used for the first time for a new purpose and on a large scale, there are still some challenges here that have to be mastered. In the presentation we will address some of them.

Can Machine Learning Bring Disruptive Innovation in PLC ?
Abstract: Significant innovation to power line communication (PLC) has been introduced in the last 20 years. PLC has reached high technology maturity, but moderate market penetration w.r.t. the expectations facing competition of wireless systems and the perduring (to some extent unjustifiable) criticism about its massive adoption in smart grids. The pace of innovation of PLC appears decreased, despite some recent IEEE and ITU standardization endeavors that leverage existing solutions through optimization and better customization to specific application domains. Improvements are still possible at all protocol stacks and it would be desirable they were not limited, at least in theory, by fundamental bottlenecks (which is a catchy selling point of wireless). Machine learning (ML) has powerfully penetrated many research fields including communications. It has proven to be disruptive in several domains, but the added value is still unclear when it comes to communication networks. There are two main aspects that need to be considered: a) the identification of the problems to be better solved with ML, b) the design of ML architectures tailored to communications.
In this keynote, we elaborate on both a) and b) looking at all PLC layers. Starting from the physical layer, we report recent results about learning methods for the statistical characterization of the channel response and noise in multiple conductor power lines revealing intriguing new features. Synthetic channel and noise modeling exploiting generative adversial networks (GANs) is presented. A novel methodology to learn the channel capacity (which is still unknown in PLC) exploiting the notion of autoencoders is illustrated. New modulation techniques and ML detection mechanisms are discussed. Then, moving to the upper layers, the challenge of improving routing in large PLC access networks using ML is discussed. Finally, we briefly argue on what ML can bring w.r.t. to model-based signal processing approaches for power grid diagnostics. In reference to b), we present recent work on segmented generative neural networks with data generation in the uniform probability space, which is a flexible/scalable architecture for the considered applications.
