This paper describes the design and implementation of a Multi-Agent System (MAS) that provides a distributed algorithm for fault location and isolation in power distribution systems. The designed MAS locates and isolates the fault based on locally available information. Agents are implemented using power quality meters and rugged processors which communicate with MAS through serial and TCP/IP communication links.The system is intended for studying the fault location and isolation algorithm and analyzing the communication media performance.
Modeling, Simulation and Decentralized Control of Islanded Microgrids Farideh Doost Mohammadi This thesis develops a comprehensive modular state-space model of microgrids containing inverter-based Distributed Energy Resources (DERs). The model is validated and then used for small signal stability
Abstract-Appropriate control of high penetration renewable energies in power systems requires a complete modeling of the system. In this paper, a comprehensive state space modeling of voltage source inverters, networks and loads are studied. We have modeled a secondary voltage control that utilizes the nominal set points of the output voltage as the input for the controller design. A distributed control algorithm only requiring a sparse communication between neighboring distributed generators (DGs) is used. The proposed secondary voltage model is applied on a microgrid with three DGs and two loads to verify the results.
