    Abstract

    This paper presents the modelling and load flow simulation of a low-voltage distribution DC microgrid which is developed in the test area of the Group of Studies and Development of Energy Alternatives (GEDAEUFPA).
    This microgrid is intended to serve as a basis for conducting tests of operation modes, power conditioning devices, control strategies, among other possibilities, as well as applications related to low voltage direct current
    distribution systems, and to validate mathematical models of related processes. The simulated microgrid structure is composed of three photovoltaic generators of 500 Wp each, a battery bank of 4.8 kWh, three charge controllers
    forming a 24 V DC bus, and load banks distributed along a grid with a total length of 200 m. The modelling of microgrid components are presented in detail, and the load flow study used is derived from the traditional Newton-
    Raphson power flow algorithm used in AC systems.
