Abstract:

This paper presents a robust resilient sparse voltage control framework for low-voltage DC microgrids consisting of multiple distributed generation (DG) units with uncertain loads. To this end, a multiple-DG DC microgrid with arbitrary topology is cast as a linear time-invariant (LTI) interconnected system subject to structured uncertainty. By means of this modeling framework, a systematic convex-optimization-based approach for the design of sparse voltage control is proposed. The proposed voltage control strategy regulates the voltage of DG units at the point of common couplings and is simultaneously robust, resilient, and sparse. The effectiveness of the proposed sparse control scheme is verified through detailed simulation case studies.

I. Introduction

DC microgrids have received increasing attention due to the high depth of penetration of renewable energy sources with DC output type such as photovoltaics (PV) and fuel cells, DC loads, and energy storage systems. Moreover, the significant advantages of DC microgrids compared to their AC counterparts in terms of higher efficiency, reliability, and simpler control mechanisms have enhanced their applicability in many critical applications such as aircraft, trains, electric vehicles, naval ships, and telecommunication systems [1]– [3].
