Recently direct current (DC) microgrids have drawn more consideration because of the expanding use of direct current (DC) energy sources, energy storages, and loads in power systems. Design and analysis of a standalone solar photovoltaic (PV) system with DC microgrid has been proposed to supply power for both DC and alternating current (AC) loads.
Solar energy is an important part of a DC microgrid, with the main goals to save energy costs and reduce dependency on the AC power grid. A dedicated power converter conditions the variable voltage from the solar panels to a stable DC link voltage.
DC microgrids are localized energy systems operating from a DC bus within a defined voltage range. These systems can vary greatly in size and power, from small islands with several motors on a shared DC bus up to large-scale applications, such as entire factories or data centers with combined loads reaching up to the megawatts.
The performance of the adopted method for minimizing battery energy utilization in a stand-alone DC microgrid system is investigated through simulations carried out in MATLAB 2014a on a system with an i7 processor, 3 GHz frequency, and 8 GB of RAM.
