要約(日本語): “Coherent based” aggregation methods are preferred by utilities than “Eigenvalue based” method because of its definite physical expression in spite of its uncertain accuracy. Aggregation error of “Coherent based” methods consists of “Network aggregation error” and “Generator aggregation error”. The paper focuses on the former by regarding all generators to be aggregated as having the same character. The paper lists up physical variables that are desirable to preserve through aggregation, and arranges various network aggregation methods as selection of variables to be preserved through aggregation. Accuracy of various “Coherent based” network aggregation methods are assessed using four example systems considering induction motor load and load branch.
