TLDR
Depending on the type and depth of penetration of distributed energy resource units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems.Abstract:
The environmental and economical benefits of the microgrid and consequently its acceptability and degree of proliferation in the utility power industry, are primarily determined by the envisioned controller capabilities and the operational features. Depending on the type and depth of penetration of distributed energy resource (DER) units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems.read more

Control model for distributed generation and network automation for microgrids operation
Vinicius Cabral do Nascimento,Germano Lambert-Torres,Claudio Inacio de Almeida Costa,Luiz Eduardo Borges da Silva +3 more
TL;DR: In this article, the authors describe a model for power distribution grid simulation with distributed generation, designed to be a simulation environment of two proposed elements: (1) an algorithm to reconfigure the circuit topology to enable a microgrid during an outage of power supply, and (2) a specific limiter to allow safe operation of distributed generation in the network.
