As the transition to alternative forms of energy such as sun and wind gains momentum, new challenges arise to integrate them into the grid. First one is to store exceeding energy when demand is low and reinject it when peaks of consumption arise. Second is the stability of the grid. Energy storage is part of the answer to those challenges and a key part of the standard power supply solutions of the future. AEG Power Solutions has the unique combination of expertise in power electronics, UPS, grid integration and battery to design and provide the core power electronics components of any battery energy storage system, which can match specific application needs from voltage regulation to full off-grid power generation.
