Control of a utility connected microgrid
This paper describes the control algorithm of a utility connected microgrid, based on independent control of active and reactive power (PQ control) and working in centralized
operation mode. The microgrid under investigation is composed of three configurable units: a generation unit, a storage unit and a load. These units are interfaced with the microgrid through a
Voltage Source Converter (VSC) and are controlled by the nodes of the communication system by means of IEC 61850. A set of
tests have been conducted to evaluate the microgrid behavior.Postprint (published version

Design, management and comissioning of a utility connected microgrid based on IEC 61850
This paper presents an approach to microgrid
automation. The microgrid is composed of three different nodes connected to the public electric grid, which are hardware
emulated with back-to-back converters. The microgrid is a flexible and weather independent test bed for testing different
control algorithms. The intelligence of the automation system is split in three hierarchical layers: the RMU layer, the iNode
layer and the iSocket layer. Communications among iNode and iSockets are according IEC 61850 standard.
The aims of the project is to comission a set of technologies and acquire experience in microgrid automation, IEC 61850
communications and power control algorithms in DER systems
