A power system that mainly bases on renewable energy sources leads to a higher demand on ancillary services. To ensure the stability of the network, new approaches need to be developed. This paper analyses the potential of small run-of-the-river hydro power plants for participation in the German balancing power market. For this, the necessary technical(More)
A high penetration of distributed energy resources results in an increasing network voltage in times of high feed-in. Therefore, an efficient voltage control is required. Small run-off-river hydro power plants offer the opportunity to control the network voltage by reactive and active power. Thus, these units have to be connected to a virtual power plant.(More)
Renewable energy sources as well as heat pumps become more important in the building sector. To analyze the operation of these units in a net zero-energy office building (nZEB), a case study was performed by Daikin Europe NV and Athoka GmbH. Thereby, a sufficient energy management system is used to coordinate the power supply and demand. For this reason,(More)
The increasing share of distributed energy resources, which will be connected to electrical networks in the future, requires innovative network structures to ensure a reliable energy supply. The integration of electrical energy storage devices will become more and more important in this context. Within this paper, an energy storage management system will be(More)
Due to the increasing share of distributed energy resources, which will be integrated into the electrical grid within the next decades, innovative grid structures and management concepts are required to ensure a reliable supply of electrical energy in the future. The integration of energy storage devices will become more and more important in this context(More)
