The CRISP project has investigated, designed and tested ways in which ICT innovation can be exploited for cost-effective and reliable monitoring, management and control of power networks. Software was designed for the development of interactive intelligent distribution networks with improved regional monitoring and control potential within a new integrated EU-distribution network. Numerous laboratory and field tests were conducted in various countries which resulted in practical advice for the use of intelligent ICTs in high-DG power networks. Following this, a detailed description of the power system was created to examine technical consequences and blackout countermeasures, mainly linked to transmission. It defines important events and defence plans. Furthermore, a specific criterion was suggested because of its ability to indicate the real time situation regarding stability. The real time evaluation of stability occurs cell by cell and is combined at a higher level. This enables a more intricate stability study with the use of a scalability parameter which simultaneously accounts for local and global constraints. Moreover, future demands for control and communication are specified for different types of power system applications on a local scale.
