The reason for microgrid current sharing is
The control objective is guaranteeing voltage stability in the DC microgrid while delivering power to the loads and extracting energy efficiently from renewable sources. However, a key challenge arises when connecting these converters to a common DC bus: maintaining voltage regulation and accurate current sharing. It highlights the importance of proper current sharing to avoid overloading converters and circulating currents in microgrids.Read More Download PDF
DC microgrid bus voltage fluctuation
This study proposes an integrated control method for the bus voltage of the DC microgrid to solve the abovementioned problems. As a result, DC bus voltage suffers from rapid changes, oscillations, large excursions during load disturbances, and fluctuations in renewable energy output. Energy storage devices can provide equivalent inertia. To enhance the inertia and response speed of the DC bus interface converter, this paper proposes a power allocation. . Aiming at the problem of bus voltage control in DC microgrid, a dynamic compensation control strat-egy based on a residual generator is designed to complete the voltage compensation of DC-DC con-verter.Read More Download PDF
