This article aims at addressing distributed averaging problems for signed networks in the presence of general directed topologies that are represented by digraphs. A new class improved Laplacian potential functions is proposed presenting two notions any digraph: induced unsigned digraph and mirror (undirected) graph, based on which protocols designed using nearest neighbor rules. It shown with ...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

Currently, manufacturing enterprises face increasingly fierce market competition due to the various demands of customers and rapid development economic globalization. Hence, they have extend their production mode into distributed environments establish multiple factories in geographical locations. Nowadays, systems been widely adopted industrial processes. In recent years, many studies done on ...

In this paper, a robust local controller has been designed to balance the power for distributed energy resources (DERs) in an islanded microgrid. Three different DER types are considered in this study; photovoltaic systems, battery energy storage systems, and synchronous generators. Since DER dynamics are nonlinear and uncertain, which may destabilize the power system or decrease the performanc...

This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...

with increasing the presence of microgrids (mgs) in the power systems, investigating the mg stability during transient faults is necessary. this study investigates the transient stability analysis of a mg supplied by multiple inverter interfaced distributed generations (iidgs) during fault. the transient stability of a mg is highly depends on the iidgs control strategy. a mg, simulated on matla...
