Enhanced Power Sharing Accuracy in Islanded Microgrids with Local Loads: An Approach to Droop Control Techniques

Droop-based control is widely used in islanded microgrids to regulate power sharing among distributed generators (DGs) according to their ratings, without the need for communication. However, simultaneous and accurate active and reactive power sharing regulation represents a key challenge for droop-based techniques. This issue arises due to the inconsistent voltage drops in feeder lines and the distinct local loads distributed across the microgrid DGs. To this end, this paper introduces a new solution for droop-based approaches to enhance power sharing accuracy in the context of local loads, without relying on any communication means between DGs. The proposed solution effectiveness is demonstrated through MATLAB/Simulink and is validated for conventional, inverse, and angle droop control.
