Modeling of DC House Distribution Network

This paper presents modeling and simulation of a distributed network of DC Houses using 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 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.
