English abstract:
Within the last 2 years more than 36,000 battery storage systems in combination with PV systems have been installed in Austria and Germany. These systems are mainly used to increase the on-site usage of PV energy. However, charging the battery without considering the feed-in power of the PV and the current state of the grid will not relieve the grid. Therefore, the benefit for the grid or the energy system of these battery storage devices is currently poor. Taking into account the subsidies from public authorities it seems to be economically feasible, to use these battery systems within a defined scope also for system or grid relevant applications.
A possibility to relieve the grid is to use battery storage systems to smooth the feed-in of PV. Another option is to use battery storage systems to smooth load peaks of a building, mainly caused by heat pumps or other electric heating or cooling systems. Within the research project "SPIN.OFF" a self-learning artificial neural network will be developed to predict the energy demand of buildings. Based on this consumption forecast as well as on the PV production forecast a charging/discharging schedule for the battery storage system, primarily focussing on the reduction of load peaks, will be created by a MPC controller.
Beside these local strategies, there are also system or grid relevant applications, which require coordination by certain stakeholders e.g. the grid operator. Such applications are e.g. the use of storage devices to balance generation schedule deviations within a balancing group or to relieve the grid by charging or discharging the battery storage depending on the current state of the grid. Within the research project "MBS+" a concept for a decentrally-organized battery-storage-network will be developed, to enable the usage of battery storage devices for such coordinated system- or grid relevant applications.
