Optimal Service Restoration Strategy for Smart Grid under Single and Multiple Fault Conditions

The distribution system plays an important role in the power system to meet out the power demands of the utility customer. It may lose its stability due to the influence of faults which leads to interruptions in supply to the utility customers. Therefore, the utility should take immediate necessary measures to ensure the quality of supply and restored the system to optimal that can satisfy all the constraints of the power system. This research work focuses on joined service restoration and optimization. Service restoration is done through restructuring and optimization is carried out through Stud Krill Herd Algorithm (SKHA). The distribution system optimization is achieved by reconfiguration and capacitor placement. SKHA is utilized for handling reconfiguration and optimal capacitor placement simultaneously. The effectiveness of the proposed strategy is validated by implementing two benchmark case studies namely IEEE 33 Bus Radial Distribution System (RDS) and Taiwan Power Distribution Company (TPDC) System.
