Result description
The methodology enables the evaluation of the required size of a BESS installed at the interconnection of a distribution grid with the transmission system in order to limit the active power ramp-rates to values commonly agreed between the TSO/DSO.
The methodology includes a specific control loop of the BESS to limit the ramp-rate to specific targets and to restore the state-of-charge of the BESS in a reasonable time frame (some minutes) so that the ramp-rate limitation can be subsequently performed either for positive or negative ramps. Based on the developed control and on the distribution grid data (load variation, topology, DRES penetration and DRES types) an analytical tool is also provided enabling the evaluation of the size (in terms of power and energy) of the BESS.
Addressing target audiences and expressing needs
- Grants and Subsidies
- Business partners – SMEs, Entrepreneurs, Large Corporations
Firstly, we are looking for partners (mainly utility-scale BESS manufacturers, DSOs, Aggregators and TSOs) to pursue demonstration projects to advance the maturity of the product to TRL6-8. Secondly, transfer the findings/ Intellectual Properties to BESS manufacturers and Aggregators.
- Public or private funding institutions
- Other Actors who can help us fulfil our market potential
- Private Investors
R&D, Technology and Innovation aspects
Currently the methodology has undergone successful testing in the lab of University of Seville, Spain. The test in relevant lab environment (reduced scale CIGRE benchmark gird) is to be finished in summer 2021. Next step required is the testing in actual relevant environment to reach TRL 6-7. Private investors and/ or public funding institutions are welcome to enable such demonstration.
The methodology is scalable because all the distribution grid elements that affect the control and the sizing are introduced as parameters.
The methodology is replicable because all the distribution grid elements that affect the control and the sizing are introduced as parameters.
BESS are already used for RRL in relatively weak electric systems (Ireland, Hawaii, Puerto Rico). Their use in stiffer systems is expected to expand in the future due to the increase of DRES penetration.
