The increasing amount of distributed generations (DGs) in today’s highly complex restructured power networks gives more options for distribution system operators under contingency conditions. A low voltage distribution network with large amounts of small sized DG can be operated as an isolated system if the distribution system is disconnected from the main grid due to contingency. In order to successfully operate in island mode, the possibility of small power islands within the distribution system needs to be considered. Clearly, the control and management of these small power islands are important, and overall network synchronism must be ensured in the isolated distribution system. In this paper, the modified IEEE 9 bus system was used to investigate the transient and steady state performance during islanding operation. The case study network was simulated with Real-Time Digital Simulator (RTDS). Also, some motivation for developing Distribution Network Islanding Ontology (DNIO) based on multi-agents systems and JADE is discussed. Despite its small size of the case study system, it mimics very closely the behavior of typical distribution networks in actual operation. Test results show that three DGs connected in the distribution networks are capable of operating in the islanding mode without sacrificing the system stability.
