The Energy Alliance deals with four key topics: While "system management within the distribution grid" covers the intelligent control of the distribution grid in view of the increasing supply from decentralized and fluctuating energy sources, "system management and stability of a hybrid transmission grid" investigates the structure and operation of a HVDC supergrid superimposed to the existing HVAC network. New technologies will be required to implement and manage the so far not existing HVDC grids. The latter topic, in addition, deals with the development of suitable equipment based on novel technologies, e.g., high temperature superconductivity. A further aspect is the development of innovative methods and technologies which ensure grid stability. As, due to the decrease of conventional power plants, the number of rotating masses of turbines and synchronous generators - which today provide the so-called instantaneous reserve that balances the difference between generated and consumed power - also decreases.
The topic "integration of storage systems into the future power grid" focuses on the interconnection of the electric power grid and the gas distribution network using the latter for storing that amount of electrical power, generated e.g. by wind power plants, which is not instantaneously consumed. Last, but not least, the Energy Alliance deals with "comparative technology evaluation" based on different criteria such as economic efficiency and contribution to the energy turnaround.
