Control of Renewable Distributed Energy Sources in Microgrids

Abstract

This thesis studies and designs a microgrid with the following characteristics: alternative current, low voltage and grid-connected, features photovoltaic power generation, a suitable storage system and dynamic loads, able to manage zero-net metering with the main grid to which is interfaced. This project also discusses main components of the microgrid providing theoretical principles on how it is modelled using software MATLAB/Simulink, showing graphical results of main simulations operated throughout the work. Particular focus has been given to describe main control techniques of the power electronic devices needed in the model. A suitable control system for each component object of the study is provided for the correct operation of the microgrid.
