Determination of load schedules and load shifting potentials of a high number of electrical consumers using mass simulation

The massive growth in the usage of renewable, but fluctuating energy sources in connection with the energy turnaround calls for a similar growth of the integration of flexible loads. This seems to be a vital aspect to maintain the balance between production and consumption in the transportation grid as well as in the distribution grid at low voltage level. In this regard the question of how to achieve a flexible and cost efficient mass integration of low power demand facilities like domestic heat pumps is of special interest. The Center for Demand Side Integration at the University of Applied Sciences Hamburg and Energie Baden-Wurttemberg (EnBW, the 3rd largest utility in Germany) developed and tested control algorithms in a simulation project in order to integrate a large number of distributed consumers (several 10.000) into an integrated system. The behaviour of the system was analysed with regard to load prediction, scheduling and shifting potentials. (4 pages)
