The SmartGrid concept stands for connection and control of energy sources; its storage and load owe to an “intelligent” power grid. Using Smart Grid technologies will assist in making the energy transition to 100% renewables more affordable.

The leXsolar-SmartGrid Ready-to-go kit allows the construction of a smart grid with a variety of renewable energy sources. It’s possible to choose different energy generation profiles and observe their effect on the system. The various available storage units and consumers make for a complex smart grid and a multitude of possible scenarios to analyse. The energy flows within the smart grid can be read directly from the displays of the smart meters. This enables the students to control the system manually. All necessary SmartControl components for measuring and control are already included. The package includes wind and solar power as well as fuel cell, storage technology and e-mobility components and, thus, also the foundation for a variety of basic experiments.
