Intelligent power conversion for smart grids | Danfoss energy storage improves power quality. Traditional grid: The consumer load creates peaks on the supply network. Smart grid: Battery storage removes the power peaks on the supply network, so the consumer load causes virtually no disturbance to the grid. This results in good power quality and ideally enables us to scale down the distribution infrastructure, saving cost.
