Description

The i-Sare microgrid has a peak installed generation power of 400 kW and consists of a load and generator system, as shown in the figure below, which can operate both when connected to the electric distribution grid or in isolation.

It is for this reason that it applies different integrated technologies based on renewable
energy production sources, in addition to conventional generation means, thus establishing smart management and storage systems for all the electric energy produced.
 
The grid has a total (peak) installed power of 400 kW. The nominal (emulator) power is of 60 kW. As shown in the general diagram below, the equipment is separated into different areas that are interconnected by means of 400 kW of triple-phase power and connected to Iberdrola’s grid through the electric grid’s transformation and connection centre. This centre houses the control systems, transformers and elements for re-connection to the medium vol- tage grid.
 
Services offered
 
The i-Sare project is an experimental microgrid in the shape of a testing bench. The aim is for it to act as a platform for developing new products, equipment, systems, and operating and maintenance procedures for the companies, universities and research centres that may require such services.
 
It can be, and indeed is, used in the consortium’s own research projects, but also serves as a testing platform and laboratory for technology companies and centres in general.
 


[1] It is understood that managed power that is able to manage the control of the infrastructure. In laboratories without physical equipment (simulators, systems) This field does not apply.
[2] Microrred function if there are loads in the same location, generators and optionally storage, with integrated management of the whole.

PROJECTS

 

Future plans

Although by now it is an experimental microgrid for demonstration of generation, storage and microgrid control technologies, in the future (from 2013) it will be extended with testing functions of microgrids components:
  • Renewable generation systems (different technologies, performance test, storage in- tegration, control evaluation of PQ, Vf , safety and security systems , ...).
  • Storage systems (idem).
  • Elements of Power Electronics (idem).
  • Testing of Electrical Machines (transformers , motors, generators , ...).
  • Long-term trials with different scenarios.
  • To test control strategies (central control, electric devices, distributed controls, har- monic control and load balancing , ...).
  • To test smart meters.
  • To test communications systems (Ethernet , RS485 , WIFI ...).
  • To test network protection elements: switches, relays.
