Abstract:

To avoid the above problems, a collaborative planning method of flexible interconnection devices for distribution networks is proposed considering integrated profits. With the installation location and capacity of soft open point (SOP) optimized in multi-voltage level distribution networks, the operation in normal and the supply restoration in fault are both improved, promoting the system’s integrated indicators of economy and reliability. Finally, the case study is conducted based on an actual distribution network data in Hebei province, verifying the effectiveness of the proposed method and analyzing the improvement of economy, safety, and reliability.

Key words: distribution network, plan and design, flexible interconnection device, soft open point
