The scope interdisciplinary and multi-user facilities for studying intelligent electrical networks is very diverse.
European Union studies indicate that “a research infrastructure is required to test prototypes and systems, to verify the interoperability of these new systems, to assess their performance and system-wide integration and also to certify their compliance with related standards as well as among the relevant standards “…” Only through well-defined research programs and environments capable of accurately reproducing real-life scenarios can the uncertainties of the application of these new technologies be minimized. “
It is in this scenario that the Lab-REI – Laboratory of Intelligent Electrical Networks is inserted, whose schematic design is indicated in the following figure.
With an installed capacity of 100 kVA, in addition to the availability of sources and programmable loads, which combine real loads and sources, connected by means of cables in real dimensions of low voltage distribution networks, the structure allows laboratory studies that reproduce with great fidelity real situations of this type of network, in which exist distributed sources, accumulators of energy and electronic loads. It has a network of communication between the agents and a data processing system that enables a centralized, coordinated and collaborative management of the various components of the system.
Equipment is expected to be in full operation at the end of 2018.
LabREI will be installed in the Faculty of Electrical Engineering and Computing of Unicamp.
An internet platform will be implemented to visualize electric power data as well as the active functions in each device that makes up the network (converters, meters, etc.). Such a platform will allow an external user to monitor the operation and results of the activities in LabREI.
With respect to the remote control of LabREI or its subsystems, it is expected to provide a section of the online platform that allows an accredited external user to change parameters of the network equipment (sources, converters, etc.) in order to control the operation and monitor results at a distance.
A roadmap to be followed by users outside UNICAMP who wish to use LabREI to validate related methodologies or experimental trials will be drawn up. Such procedure will contain technical information, scheduling form, responsibilities, maintenance costs, disclosure policy, among other relevant information, following FAPESP guidance.
