ADRES-Concept - Autonomous Decentralised Renewable Energy Systems


The research project ADRES-Concept deals with the technical feasibility of fully autonomous-decentralized renewable energy systems.

On the production side, the project involves the enhancement of the predictability and forecasting technique of wind and photovoltaic for several Austrian regions. Furthermore, selected energy converters are analysed and tested in a simulation environment.

The project ADRES-Concepts addresses on the consumption side the segments: electrical household consumption, energy demand for heating buildings and energy needs of motorised individual transport. To analyse the electrical household consumption more precisely, a comprehensive database was created using a large-scale questionnaire survey. These analyses were accompanied by a series of measurements of about 40 total households, setting a new standard in terms of size and level of detail. A MATLAB simulation tool was developed, which allows to model load profiles of households according to various criteria (household size, type of building, day of week, seasonality). The building structure was integrated by modelling several types of buildings and the future thermal energy requirement was determined. In the field of “electric mobility” also a MATLAB simulation tool was developed to ascertain charging profiles of battery powered electric vehicles at different charging infrastructures and parameters.

Another focal point of the project ADRES-Concept is the energy and power balance of the stand-alone power system. In a first step, criteria for a favourable composition of the renewable energy mix (PV, wind, biomass, small hydro) and the storage size were identified. For the simulation and design of such energy systems of several residential areas in different regions of Austria an user-friendly and comprehensive power balance tool with graphical user interface was programmed in MATLAB, which helps to derive conclusions about the power-autonomous energy supply. Another section deals with the specific energy storage selection accordingly required properties. Of equal importance is the analysis of the feasibility of using frequency control, which is carried out in a real-time power balancing routine.

It has been shown that an autonomous full supply would be technically feasible on the assumption of current consumption behaviour, but considering the existing interconnected power grid it does not make sense from an economic point of view. The switch to a power supply system with a high proportion of renewable energy sources only seems reasonable together with increasing efficiency and saving energy at the same time. The synergy of sustainability and efficiency is of utmost importance. It is perfectly obvious that every unconsumed kilowatt hour which does not need to be produced or stored, automatically leads to the highest efficiency and of course facilitates energy balancing.


As part of the research project ADRES-Concept headed by the Vienna University of Technology (Institute for Energy Systems and Electrical Drives) a dataset of high resolution electric power and voltage profiles of Austrian households was generated. The measurements themselves were carried out by the network distribution provider Energie AG OÖ Netz GmbH. In addition to that the measurements were finally validated and formatted by the AIT - Austrian Insitute of Technology (Energy Department, Electric Energy Systems).

The ADRES-dataset includes the electric active and reactive power as well as the voltage levels of each phase. The measurements were taken for one week in the winter (between September to December 2009) and one in the summer (between May to October 2010) in 30 different households in Upper Austria. They were taken with a resolution of 1 secound (RMS values).
