A New Searching Method for Intentional Islanding of Distribution Network

According to the distribution network with wind power formulated offline island plan and implementation with online island search. In the formulation of offline island plan only to ensure that important load power supply, alternative power supply path; when online search according to the real-time output power of wind turbines, under the premise of the power constraints, with the new online search algorithm to generate the most divided island trees, to maximize power supply area. As a case study, PG&E69-bus test system is used to divide island, the result proves that this proposed method is feasible and effective.
