Introducing matrix in islanding operation

Splitting strategy is to ensure continuity of power system when islanding operation is unavoidable. Through the centralized control scheme, the dispatch center should decide which transmission lines to be opened to split original network into islands. This paper proposes a feasible splitting strategy by exploiting extended incidence matrix apart from neither random search nor the graph theory to determine the splitting strategy for the islanding operation. A concept using limited cutset elements was introduced with virtual network reconfiguration plan. The optimal system configuration is then to be chosen from those candidates to fulfill operational constraints. Operational constraints related to asynchronous generator, power imbalance and line capacity limits should be achieved. Simulation results on IEEE 30-bus test system show that this heuristic method is practical rather than analytical method.
