This project involves the development of electronic equipment, in laboratory testing phase, that can control voltage in an electricity substation and allows the frequency of an isolated system to be kept constant.
The aim and focus of the project is to design, manufacture, test and validate under laboratory conditions a modular and compact hybrid FACTS prototype device with integrated fast storage systems (ultracapacitors (UC) or other technologies with similar characteristics, such as Li Ion technology) with high charging and discharging rates applied to electricity transmission grids in order to manage voltage and frequency level, as essential parameters that provide stability to an electricity system.
The project is funded by the CDTI and the European Union through the European Regional Development Fund (ERDF) and supported by the Ministry of Economy and Competitiveness.
Using this type of FACTS devices is particularly relevant in certain locations in the transmission grid, where instabilities in voltage or frequency may happen and for which the possible solutions are to reduce grid meshing (thereby reducing the safety margin to handle fluctuations), apply generation redispatch measures or load sheddings (with the consequent additional costs for the system). Therefore it is necessary to have efficient and rapid response elements available in order to maintain stability.
The project is scheduled for completion in December 2017.
GreenPower Technologies is leading this project with the collaboration of Red Eléctrica of España and Cobra, as well as through subcontracted services from the University of Las Palmas de Gran Canaria and the Association of Research and Industrial Cooperation of Andalusia.
Applying these technologies will significantly change the electricity grid system as we know it today. While maintaining the same level of security, the grid will need less development, thereby reducing the impact on the environment as a result of the reduction in the number of new facilities that could be needed or by reducing the number of disconnections of renewable generation. The application of these new technologies will lead to an improved use of the grid, allowing the significant volume of existing renewable generation to be integrated into the electricity system.
