Keynote Talk : Energy Informatics in Cyber Physical Systems : Challenges and Opportunities

Abstract :

Cyber-physical systems (CPS) are comprised of interconnected distributed sub-systems that utilize information and communication technologies (ICT). These systems are often controlled by human beings, leading to the term human-centered CPS (HCPS). An example of an HCPS is Smart Grid where the human involvement is through the Grid Operator. In the last decade, governments and regulatory bodies have been actively seeking ways to decrease our carbon footprint. Thus, the first part of this talk will provide a brief introduction to human-centered cyber physical systems, the process of feedback control loop in HCPS, the change of paradigm in the power grid, the new emerging field of Energy Informatics and its underlying challenges.
The second part of the talk will focus on showcasing three specific use cases of Human-centered CyberPhysical Systems (HCPS) within the context of Smart Grid. These use cases include Data Centers (DC), Smart Buildings, and Electric Mobility. The talk will delve into energy minimization and peak power reduction techniques related to DCs. The implementation of a feedback loop will be clarified, and a high-level overview of each technique will be provided. The talk will demonstrate that it is indeed possible to reduce energy consumption and peak power demand in DCs, both in single-site and federated-site scenarios. In the realm of Smart Buildings, certain challenges will be addressed, such as the optimal charging of energy storage systems using PVs (photovoltaics) and the prediction of temperature setpoints for Smart Thermostats using peer-to-peer (P2P) learning scheme. Additionally, the Electric Mobility System Architecture Model (EMSA) will be introduced as part of the discussion. The talk will be concluded with some key learnt lessons and some future perspectives.
