Grid-control - Implementation of the grid traffic light concept in a field test

The grid traffic light concept is an approach for the coordination of flexible units in distribution grids. The implementation and testing of this concept is addressed in the project grid-control. A quota model and a decentralized automation system are developed and introduced for the yellow and red traffic light phase. Both are tested and evaluated in a field test in a medium and low voltage grid section located in southern Germany. The results show that congestion can be efficiently avoided by the quota model. Furthermore, enhanced control methods for aggregated feed-in management can be demonstrated.
