摘要

Based on different grid development periods, this paper proposes a new method on how to select main electrical connection in different development periods. The annual investment cost function and minimal cut-set reliability model is combined in the proposed method. In different 110kV and 220kV grid development periods, the main electrical connection model based on much survey is helpful for grid planners to find the fragile part and enhance reliability. Thus, the research could provide some valuable help in decision-making process for planning in power system.
