AB Direct current microgrids (DCMGs) are currently presented as an alternative solutionfor small systems that feed sensitive electrical loads into DC. According to the scientific literature,DCMG maintains good voltage regulation. However, when the system is in islanded mode, verypronounced voltage variations are presented, compromising the system"s ability to achieve reliableand stable energy management. Therefore, the authors propose a solution, connecting the electricalnetwork through a grid-tied voltage source converter (GVSC) in order to reduce voltage variations.A coordinated control strategy between the DCMG and GVSC is proposed to regulate the DCvoltage and find a stable power flow between the various active elements, which feed the load.The results show that the control strategy between the GVSC and DCMG, when tested underdifferent disturbances, improves the performance of the system, making it more reliable and stable.Furthermore, the GVSC supports the AC voltage at the point of common coupling (PCC) withoutreducing the operating capacity of the DCMG and without exceeding even its most restrictive limit.All simulations were carried out in MATLAB 2020.
