Abstract
The plug-and-play nature of distributed generation (DG) units in converter-interfaced microgrids imposes significant challenges from the control point of view, mainly caused by the time-varying microgrid structure. In this paper, we propose a systematic plug-and-play decentralized voltage control solution for DC microgrids. The proposed control approach guarantees the stable operation and satisfactory performance of microgrids under the arbitrary interconnection of DG units. Based on the Lyapunov method, concise stability and L2 gain voltage tracking performance certificates for DC microgrids are derived. The main feature of the proposed control approach is the decentralized design of local voltage controllers in DC microgrids. The proposed voltage control framework is applied to a case study of a multiple-DG DC microgrid in MATLAB/Simscape Electrical environment.
