Abstract
The electricity consumption in residential buildings is on the rise due to the increasing incorporation of heating and cooling loads along with the increasing penetration of electric vehicles. According to the Internal Energy Agency (IEA) word energy outlook 2020, the residential sectors account for 26.9% of the world’s final total electricity consumption. With changing house loads dynamics to DC, a significant amount of energy is lost due to AC to DC conversion. While the utility grid is AC in nature, it is high time to evaluate more efficient building level distribution to cater to the changing load dynamics, as highly efficient DC loads are replacing the conventional AC loads in modern buildings. But even with higher efficiency with DC systems, the shift from AC to DC residential network is likely to be gradual with a utility distribution grid at AC. It is therefore imperative to integrate the legacy AC networks with upcoming viable DC-based technologies. In this talk first I will discuss the method to evaluate the legacy AC networks with increasing DC-based penetration to enhance their utilization factor with the optimum solar PV operation with Uninterrupted power supply (UPS) charging. Then, a framework for analyzing the impact of various DC voltage levels based upon the loss analysis is developed and will be discussed. I will further talk about the techno-economic analysis of the DC distribution system to further emphasizes the benefits of the DC-based residential architecture. At the end of the talk, I will briefly discuss the design of a residential energy management system (REMS) with the combined objectives of energy cost minimization and battery lifetime enhancement, and the possibility of bidirectional power transfer to the utility grid is also presented to assess future directions in this area.
