The constantly increasing electricity and energy demand in residential buildings, as well as the need for higher absorption rates of renewable sources of energy, demand for an increased flexibility at the end-users. This need is further reinforced by the rising numbers of residential Photovoltaic (PV) and battery-storage systems. In this case, flexibility can be viewed as the excess energy that can...
This study analyses the challenges of aggregating the flexibility of heat pumps in Austria. Flexibility can be provided by shifting electrical load to other points in time with the use of thermal storage systems. At first the potential and typical combinations of heat pumps, buildings and thermal storage systems are described. Afterwards different operation strategies and applications in smart-grid...
As the implementation of cross-border balancing markets has a lot of benefits for the participating countries and is one of the European targets, this paper focuses on harmonization issues for such balancing markets. Essential regulatory parameters for cross-border balancing markets - on national and international level - have been worked out. It is argued if these parameters need to be harmonized...
This paper discusses the impact of marked-based flexibility operation on distribution grids on both MV and LV level. Based on the gained experience in three research projects eBADGE, hybridVPP4DSO and IEA HPP Annex42, it is discussed how far market participation of flexibility resources in the distribution grid can cause grid congestions under consideration of current Austrian network planning practices...
The impact of stochastic available generation of wind power on system operation and planning gained rising importance due to the increasing amount of wind power plants. Many models used for synthetic wind speed time series are based on ARMA-GARCH processes or Markov chains. These two approaches are compared regarding their feasibility to depict the statistical properties of the original wind speed...
