A novel robust communication algorithm for distributed secondary control of islanded MicroGrids

Distributed secondary control (DSC) is a new approach for MicroGrids (MGs) such that frequency, voltage and power regulation is made in each unit locally to avoid using a central controller. Due to the constrained traffic pattern required by the secondary control, it is viable to implement dedicated local area communication functionality among the local controllers. This paper presents a new, wireless-based robust communication algorithm for DSC of MGs designed to avoid communication bottlenecks and enable the plug-and-play capability of new DGs. Real-time simulation and experimental results are presented to evaluate the feasibility and robustness endowed by the proposed algorithm.
