Market-driven flexibility of grid usage and network-oriented load balancing

In particular, the integration of renewable energies brings out new challenges for the operation and the design of power networks. Up to the year 2000 a clear vertical distribution structure and the corresponding load-flow was visible. Since that time, due to the increasing number of regenerative production plants in the lower distribution network levels, an additional horizontal utilization takes place at an increasing number of time intervals. As a result, the weaker, lower distribution structures, in which more than 75% of renewable energy systems feed in, are increasingly burdened. In combination with the lack of opportunities, e.g. the willingness of the population to demand side management and the still limited storage possibilities this means, that the network resources in these areas are partially heavily loaded. In the following paper, models and methods will be presented, which will open up opportunities to limit the load flow to the physically required by an intermittent localization of the energy usage.
