摘要
The increasing share of renewable energy resources like wind or solar power opens up interesting options for a paradigmatic change of network operation strategies. On the one hand volatile generation principally endanger robust network operation. On the other hand there is an political and ecological pressure to maximize the in-feed of renewable energy resources, like photovoltaics. There is therefore a need for a cheap and scalable solution to meet these challenges. We claim that this requires more local intelligence associated with the network elements and communication between these units. Future grid operation system will have to provide features like state estimation, voltage control and load balancing irrespective of the voltage level. Scalability is achieved if the central control task is distributed among the distributed intelligent units.
