Abstract [en]

The increasing amount of distributed generation (DG) in today's highly complex restructured power networks gives more options for distributionsystem operators (DSOs) under contingency conditions. A low voltagedistribution network with a large amount of DG can be operated as an islanded system if the distribution system is disconnected from the main grid due to the contingency. The control and management of the islandeddistribution system are important, and the overall network synchronism must be maintained in the islanded distribution system. In this paper, a multi-agentbased controller is proposed to stabilize the frequency and voltages of anactive distribution system after it enters into the islanding operation mode. The modified IEEE 9-bus system was used to illustrate the dynamic and steady state performance of the active distribution system during islanding operationwith the proposed multi-agent based controller. Case studies have been carried out using the RealTime Digital Simulator (RTDS). Case study results show that the proposed multi-agent controller can efficiently help stabilize the frequency and voltages of active distribution systems after switching toislanding operation.
