The purpose of this paper is to explore the applicability of linear time-invariant (LTI) dynamical systems with polytopic uncertainty for modeling and control of islanded DC microgrids under plug-and-play (PnP) functionality of distributed generations (DGs). We develop a robust decentralized voltage control framework to ensure robust stability and reliable operation for islanded DC microgrids. ...

Abstract— In this paper, an H∞ current controller is proposed to maintain a balanced neutral point for a three-phase fourwire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional neutral leg and a split DC link. The neutral point is balanced with respect to the two DC source terminals (as required, e.g., in neutral-pointclamped three-level ...

Abstract With the rising popularity of DC microgrids, clusters such grids are beginning to emerge as a practical and economical option. Short circuit problems in microgrid can cause overcurrent damage power electronic devices. Protecting lines from large fault currents is essential. This paper presents novel localized detection classification technique for protection clusters. In this paper, va...

This paper proposes a robust DC microgrid (MG) operation scheme for intentional power routing (PR) within the MG or between and utility grid (UG). The consists of photovoltaic (PV) system, battery energy storage system (BESS), AC loads connected to UG via DC/AC conditioning system. is achieved by controlling converter BESS in slack mode with same different terminal voltages. In this way, bus vo...

AC/DC hybrid microgrids are becoming potentially more attractive due to the proliferation of renewable energy sources, such as photovoltaic generation, battery storage systems, and wind turbines. The collaboration AC sub-microgrids DC improves operational efficiency when multiple types power generators loads coexist at distribution level. However, voltage stability analysis software validation ...
