HOME / Photovoltaic all-DC microgrid - CAPTURED ENERGY SOLAR (PTY) LTDThe power of photovoltaic (PV) and electric vehicles (EV) charging in integrated standalone DC microgrids is uncertain. If no suitable control strategy is adopted, the power variation will significantly fluctuate in DC bus voltage and reduce the system's stability.
Abstract: The increasing prominence of DC microgrids (MGs) in modern power systems necessitates effective power control and management frameworks, particularly for integrating renewable energy sources such as photovoltaic (PV) systems.
Some of the renewable energy sources such as solar and fuel cells produce DC power which is suitable for most of the existing equipment and devices such as computers, phones, LED lamps, and even electric vehicles work on DC power, DC microgrid presents itself as a more feasible alternative over AC microgrid.
The main goal of incorporating a control system within a DC microgrid is to ensure several actions such as voltage regulation, proper current sharing, import and export of power, management energy storage, protection of equipment, decreasing the loss of power, minimizing the cost of operation (Yang et al., 2017).
The ANN–PSO controller is integrated within a PV-battery microgrid system and enables efficient tracking of the maximum power output while minimizing oscillations.
The increasing prominence of DC microgrids (MGs) in modern power systems necessitates effective power control and management frameworks, particularly for integrating
The “dual carbon” strategy has drawn attention to distributed PV systems for their flexibility and variability, but the rising need for direct-current (DC) loads on the load side has created
