Consensus-Based Distributed Primary Control for Accurate Power Sharing in Islanded Mesh Microgrids

In this paper, a consensus-based distributed control strategy for mesh microgrids based on droop control approaches is proposed. The proposed control is based on a communication among local controllers capable of exchanging informations with the neighbouring distributed generators (DGs) through local low-speed communication network. It allows the DGs' active and reactive power sharing in islanded mesh reconfigurable microgrids. The efficiency of the proposed control strategy is validated based on the simulation results obtained from Simulink/Simscape of matlab and the experimental ones using Hardware-in-the-Loop (HIL) real time simulator of opal-rt and dSPACE platforms. The robustness of the proposed control is also investigated with respect to loads' variation, microgrid topology changes and communication time delays. Also, the effect of the proposed primary control on voltage and frequency deviation is investigated
