Embodiment Construction
[0027] The optimal island division strategy can maximize the advantages of distributed power, so that important loads can be restored to power during failures, and at the same time maximize the total load to restore power. However, as the scale of the system increases, the solution to the optimal island division problem faces the "curse of dimensionality" problem, and it will become very difficult to obtain the optimal island. Therefore, the purpose of the present invention is to find a practical approximation algorithm to quickly determine the optimal islanding scheme.
[0028] The present invention adopts a two-stage strategy to deal with the island division problem involving distributed power generation: first, the initial island division scheme is obtained by using the island establishment and island merging process including multiple tree knapsack problems (Tree Knapsack Problem, TKP); analysis and adjustment to obtain the final island solution. The present invention ado...
