Lagring och flexibilitet för förbättrad kapacitet i elnätet

Forskningsprojekt, 2022 – 2026

A decrease in CO2 emissions is necessary to reduce the global warming. One component in thisreduction is to reduce the use of fossil-based fuels in electricity generation and shift productiontowards renewable energy sources such as wind-power and solar-power. The shift to such sourcescomes with additional challenges for the electricity system. One important issue is the inherentvariability of such energy sources as the level of possible production changes with meteorologicalfactors beyond our control. A fundamental property for an electrical power system in stationaryoperation is that the produced electric power must equal the electric power consumed in the loads.Uncontrollable variations in either load or production must hence be balanced by changes in otherparts of the system. This project aims to study how this balancing can be accomplished from twoperspectives. In the first perspective we study how energy storage systems can be places anddimensioned to obtain optimal reduction in variability. In the second perspective we study how energymarkets can be designed to promote loads to participate in balancing the variability of the renewablesources by aligning the load level with the production levels.
