Battery control models for frequency stability in power grids with renewables

Trabajo presentado en el IFISC Poster Party (online).-- The IFISC Poster Party is an annual activity where PhD students and postdoctoral researchers of IFISC present their research in a poster format.-- Dynamics and Collective Phenomena in Social and Socio-technical Systems.The ecological transition to cleaner energy production is a fundamental part in facing the challenge of climate change. Many renewables, such as solar and wind powers, have an intermittent nature as their outputs strongly depend on factors like the weather, time of the day, season etc. This may create issues to the stability of the power grid, in particular it may accentuate frequency fluctuations. A possible solution to this problem is the introduction of energy storage systems in the grid, such as batteries. In this study we propose two different algorithms for battery operations: one is based on an optimisation technique called model predictive control which aims at smoothing power from renewables, and another which acts as an additional primary and secondary control.We acknowledge funding from project PACSS RTI2018-093732-B-C22 of the MCIN/AEI/10.13039/501100011033/ and by EU through FEDER funds, from the Maria de Maeztu program MDM-2017-0711 of the MCIN/AEI/10.13039/501100011033/, and from European Commission under Horizon2020 Innovation Action VPP4ISLANDS (grant agreement 957852).Peer reviewe
