Renewable energy microgrid: design and simulation

Abstract

This project designs, models and simulates a microgrid with the next characteristics: - Grid-connected - Zero Net-Metering with the grid (Zero Energy Building concept) - Low Voltage Direct Current (LVDC) distribution system - Solar generation - Storage system  battery - Other components: loads, electrical vehicle… This paper presents the basic theoretical principles and equations to model the main components of the system (PV panels, converters, control systems, etc) and displays the Simulink models of the different solutions found, and the graphical results obtained in the simulations. The project also discusses some very innovative issues in the power systems panorama, as the LVDC distribution system and the zero-energy building concept.
