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, the effectiveness of the energy management...
The increasing number of Distributed Generation Units (DGs) in distribution grids is challenging the way electrical systems are designed and operated. For traditional power systems, Low Voltage (LV) networks play a passive role in voltage regulation, but when DGs are present the LV network may play an active role in voltage control. In this paper, a voltage control strategy using mini Combined Heat...
A high penetration of renewable energy sources leads to a higher demand on ancillary services. To ensure the stability of the network, new approaches need to be developed. Small run-of-the-river hydro power plants offer the opportunity to control the network voltage by reactive and active power. Furthermore, the units can participate on the power balancing market to ensure the operation of the transmission...
Because of the high energy efficiency of the coupled production of thermal and electrical energy, cogeneration is a key technology of the German climate protection plan.
