Smart integration of distribution automation applications

摘要

Future electricity demand will significantly increase, while flexibility in supply will decrease, due to an increase in the use of renewable energy sources. The most effective way to prepare distribution grids for this increase in loading and decrease in supply-flexibility is to apply balancing, load-shifting, peak-shaving and other smart-grid related technologies. Without the implementation of smart grid technologies in distribution networks, it is almost impossible to keep the power supply at the current reliability and quality levels. An important factor in the success of smart grids, is the implementation of distribution automation systems (DAS). The ability to reconfigure networks, divert power flows, isolate faults and prevent overloading of network components all contributes to the optimal operation of self-healing distribution grids, which is necessary for future electricity demands. In this paper, a literature research on the status of distribution automation research is presented and an outlook towards future roles of distribution automation systems is explored. Emphasis is put on the integration of different applications in order to be able to grasp the full potential of DAS. Furthermore an elaborate case study is presented, considering the effects of DAS integration into the live distribution grid.
