In future, an increasing number of energy storages will be installed in buildings with PV systems. However, batteries with only local operation tasks do not use their complete technical potential. Using the available battery capacity in terms of power and energy to provide ancillary system services is therefore reasonable. Providing primary control reserve power in combination with increasing local self-sufficiency was identified as a promising option for decentralized PV-Battery systems. The main idea is to use part of the battery capacity to provide grid services and the remaining part for the management and optimization of local system operation. Simultaneous use of the battery to locally increase self-sufficiency reduces the need for external power sources to correct the storage level. Increasing self-sufficiency is permitted or prohibited depending on the current battery state of charge. In the following paper the operation concept, the technical solutions and a sensitivity analysis are presented.
