Abstract

This article investigates the transient performance of a stand-alone home-microgrid with similar components in three different configurations. The home-microgrid includes a set of residential loads, which are supplied with a wind turbine, a solar photovoltaic, and battery storage systems. The proposed configurations are based on the DC and AC connection of the components and the location of the battery storage. First configuration proposes a distributed battery in which each of the distributed generators is equipped with a battery in their DC links. Second configuration considers a centralized battery in the AC bus of the system in which all the components are equipped with inverters. Third configuration proposes a centralized battery in the DC bus of the microgrid in which a single inverter is used for all the components. An appropriate control system based on maximum power point tracking is provided for the renewable-based distributed generators. The voltage is controlled through a direct control of the load side converter. Simulation models are developed using MATLAB/Simulink and the transient performances of the configurations are compared in terms of voltage, frequency, and total harmonic distortion (THD).
