Parallel power system restoration after total or widearea blackout is commonly implemented by power utilities to speed up the restoration time. The procedure involves sectionalizing the affected system into a number of sub-systems or islands. This paper describes a heuristic based strategy to determine number of islands based on lowest total restoration time, TRT. The strategy involves a searching method to identify cut-set (set of transmission lines that separate blackout system to islands). The main objective of the strategy is to search the optimum lines of the cut-set which create islands with almost similar parallel restoration time. Thus, the total restoration time for complete system interconnection can be significantly reduced. Physical properties and operation data of affected system are employed in the proposed method to assist the searching process using the graph theory model. Other than that, restoration constraints such as load power generation balance and availability of black start generators are considered. Load flow analysis is carried out on the selected islands to ensure that the voltage profile stability performance is in the acceptable range. IEEE 39-bus and 118-bus system are used to demonstrate the effectiveness of the method in determining number of islands. Promising results in terms bf TRT was compared to other methods reported in the literature. |
