Email this article New Control Strategy of Interconnected Micro grids for Enhancing Power Sharing Capability
Abstract
In this paper, Due to some operational barriers to existing power management systems the AC-DC connected grids are only involved in power sharing or power control but not in both, in order to overcome these problems this paper is proposed. This proposed autonomous power control system will look at the specific state of the DC grid loading before importing power from a interlinked AC micro grid. This strategy not only converts power to a DC micro grid but also reduces the number of active converters that will reduce energy transfer losses. The proposed system is completely self-contained as it adheres to the plug-n-play features of generators and tie-converters. The effectiveness of the proposed control system is guaranteed under various operating conditions. The results reveal the usefulness of the proposed system for managing DC micro grid power shortages efficiently autonomously, while maintaining better power control and voltage regulations over the DC Micro grid. Results are verified by MATLAB / SIMULINK environment.
