Compared with AC microgrids, DC microgrids have no problems in reactive power, phase and frequency, and DC voltage has become an important indicator of system stability . In DC microgrid system, in order to ensure the stability of DC voltage, it is necessary to coordinate the control of multiple microsources.
In DC microgrid system, in order to ensure the stability of DC voltage, it is necessary to coordinate the control of multiple microsources. Reference proposed a voltage-layered coordination control strategy.
Microgrids (MG) take a significant part of the modern power system. The presence of distributed generation (DG) with low inertia contribution, low voltage feeders, unbalanced loads, specific X/R ratio and the low short-circuit power values makes the observation of the MG stability aspects different from the conventional bulk power system stability.
This article critically reviews two main aspects of DC microgrids: voltage control and power management. The challenges and opportunities for voltage control and power management in DC microgrids are discussed.
