goals

The students are able to select and design the best technical and economical storage system for the respective application. This applies in particular to storage systems for stochastically fluctuating energy sources (regenerative energies) and for low-emission traffic systems (hybrid vehicles).

content

The lecture 'Energy Storage Systems' deals with different types of storage for chemical, potential, kinetic and thermal energy and their use in power engineering systems. Building on the physical basis of the storage types, their functional principles are discussed. To structure the different types of storage systems, the performance is derived, based on the characteristic curves. For electrochemical energy storage, different types of accumulators are treated. Therefore, the different types of electrochemical processes in the accumulators will be discussed. Pumped storage systems act as a storage of potential energy and vary considerably depending on the morphological conditions of the site. In addition to the electrical subsystems, such as generators and motors, the hydraulic subsystems, such as piping systems and pumps are explained. Finally, the control of turbines, generators and motors will be discussed. Flywheel accumulators are used to store kinetic energy. Starting from the physics, the stationary and dynamic operating behavior of the electrical and mechanical subsystems as well as the entire system is considered. In addition, special technologies for the production of high-speed flywheels are introduced. For thermal energy storage systems, different principles of the storage process, such as sensitive, latent and chemical storage are presented. Furthermore, a subdivision into low and high temperature storage with examples of their different applications is given.
