Solar and smart – that’s the future of modern energy supply. Decentralized photovoltaics installations and battery storage systems for domestic power supply will be combined in intelligent networks providing balanced power to the public grid. The devices and communication technology needed for the integration of these elements – small and large electrical storage systems, intelligent transformers and virtual power plants – will be presented at ees and Intersolar Europe 2017. Electric vehicles are also part of the power grid of the future, both as consumers and as energy storage devices. Predictive energy management systems will control air conditioning and heating, charge management for electric vehicles and the smart grid function for feeding power into the grid. Intelligent power grids, or smart grids, will control and monitor power generation, store, distribute and consume electricity.
