Autonomous Power Management for Interlinked AC-DC Microgrids
1 like246 views
The document proposes an autonomous power management scheme for interlinked AC-DC microgrids. It aims to efficiently manage power deficits in the DC microgrid while maintaining good voltage regulation. The scheme prioritizes reducing the number of converters in operation to avoid unnecessary losses. Simulation results under different scenarios demonstrate the scheme's effectiveness in autonomously regulating the DC microgrid voltage and sharing power based on loading conditions. The performance was validated for variable load conditions.

CONCLUSION:
An autonomous power management scheme has been presented for interlinked AC-DC
microgrids having different configurations. The proposed scheme manages the power deficit in
the DC microgrid efficiently and autonomously. The number of tie-converters in operation has
been reduced with the proposed prioritization to avoid unnecessary operational losses. The
scheme has demonstrated better voltage regulation in the DC microgrid. The performance and
robustness of the proposed scheme have been validated for two different scenarios of the DC
microgrid at variable load conditions.

Some of the existing control schemes are designed with the main objective of sharing power among the interlinked microgrids based on their loading conditions, while other schemes regulate the voltage of the interlinked microgrids without considering the specific loading conditions. However, the existing schemes cannot achieve both objectives efficiently. To address these issues, an autonomous power management scheme is proposed, which explicitly considers the specific loading condition of the DC microgrid before importing power from the interlinked AC microgrid. This strategy enables voltage regulation in the DC microgrid, and also reduces the number of converters in operation. The proposed scheme is fully autonomous while it retains the plug-nplay features for generators and tie-converters. The performance of the proposed control scheme has been validated under different operating scenarios. The results demonstrate the effectiveness of the proposed scheme in managing the power deficit in the DC microgrid efficiently and autonomously while maintaining the better voltage regulation in the DC microgrid.
