5. Battery Storage as Grid Reinforcement for Peak Power Demands
University essay from Linköpings universitet/EnergisystemAbstract : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.
