Abstract
This thesis covers the design and simulation of a model for a distributed network of DC Houses in MATLAB Simulink. The model will allow for sharing of power between houses within the network. The developed model consists of five separate DC House branches with local power generation. Each branch consists of a PV MPPT charge controller subsystem, a resistive load, and a bidirectional buck-boost converter subsystem. The high voltage side of every bidirectional buck-boost converter is connected together through the transmission line at a single high voltage DC bus. The performance of the individual components of the model is verified before constructing the network. The power sharing capability of the network was evaluated by measuring the efficiency transmission at varying wire gauges, distances, and high-end voltages. Results of the study show that for the most part, higher transmission voltage resulted in higher efficiency. However, this was not the case at some configurations due to different methods of power sharing. Overall, the proposed design provides a viable model for a distributed network of DC Houses, which serves as a basis model for future designs of DC House network for different parameters such as capacity, size and price points.
