Abstract:
Design and development of a DC nanogrid for residential application AUTHOR: Ruben Marcos SUPERVISORS: Ángel Cid ruben.marcos@estudiants.urv.cat Abstract. This project consists on the design of a domestic DC nanogrid that afterwards is going to be connected to the AC grid using an inverter. The Boost topology is going to be operated as a Loss Free Resistor (LFR) and we will explain step by step the design criteria considered. To make sure our system is stable, we have calculated the stability margins and we have obtained the small signal transfer functions that will allow us to study deeply the performance against a specific output perturbation. After the analysis, the system has been simulated using PSIM and after that, we run the set up on the laboratory bench to verify the results obtained by the simulations. In the ‘Future Tasks’ chapter, we are going to explain all the tests done in relation with the connection of two cascaded LFR controlled by a MPPT module that will deliver the energy from a PV panel to the nanogrid. Finally, we are going to explain all the conclusions obtained through the project. Study Program: Industrial Electronics and Automatics Engineering Degree Defense Date: September - 2015
