The integrated standalone DC microgrid is modeled, which contains PV, hybrid energy storage system EV charging. For the PV power generation unit, an MPPT control based on a variable step perturbation observation method is proposed to increase the tracking speed at the maximum power point and reduce the power oscillation during the tracking process.
The energy storage unit is essential to maintain the stable operation in the standalone mode of the integrated DC microgrid. When the system power changes, the bus voltage will also change. An effective control strategy for the energy storage unit in the microgrid is needed to stabilize the bus voltage within a specific range.
Direct Current (DC) microgrids are increasingly vital for integrating solar Photovoltaic (PV) systems into off-grid residential energy networks. This paper proposes a design methodology for standalone solar PV DC microgrids, focusing on Battery Energy Storage System (BESS) optimization and adaptive power management.
In reference, the paper discusses a DC microgrid control equipped with a hybrid energy storage system comprising batteries and supercapacitors.
In this grid forming mode, the PV functions as the primary power generation source, and the energy storage systems adapt their operations to reinforce the grid voltage and sustain stability.
