Summary: | The islanding operation of a distribution network connected with distributed generation may be a useful way to improve its power reliability. However, it requires a good control strategy for ensuring a safe operation of islanded system controlling voltage and frequency of the system within their permissible range. This paper proposed a centralized controller to coordinate the islanding operation with multiple islanding configurations for rotating type DGs. Multiple islanding configurations are introduced to maximize the benefit of islanded operation. The advantage of the proposed strategy is that DG will be able to operate in different islanding areas instead of energizing only one islanding area. The proposed controller regularly communicates with the governor and excitation controllers of the DG units with the utility grid to carry out action in case of an islanding event. The performance of the proposed controller is investigated for various simulations carried out on an existing Malaysia distribution network The simulation results show that the islanding operation for each configuration is dynamically stable. |
