Abstract/Summary

In pursuit of supporting the global efforts in reducing carbon footprint and reliance on fossil fuels, this project seeks to continue the development of a hybrid AC/DC house prototype at Cal Poly State University. To enhance the power flow to DC loads, a dedicated 48 V DC bus will be constructed to replace the impractical multiple DC buses in the previous system. This iteration will also add a key feature that enables users to monitor real-time AC and DC powers. Another new functionality will involve the provision of a mix of latching and non-latching relays to switch between sources, thus ensuring that both AC and DC loads receive power. This new feature will further enable users to conveniently observe the system status and select which sources are utilized from a touchscreen. Other proposed improvements entail the integration of a control system with a Raspberry Pi and Arduino Nano and a touchscreen human-machine interface to control main components in the system. When fully completed, the hybrid AC/DC house will not only serve as a living laboratory to educate students and the community on residential electrical systems but will also serve as a demonstration site of a future Net-Zero Energy Home.
