Taking into account the layout of UHV receiving point and regulation of receiving-end network structure simultaneously, a bi-stage optimization approach was proposed to deal with the problem of receiving-end UHV network planning. In the first stage, a tri-objective optimization model(TOOM)of the UHV receiving point planning was established to maximize the strength of receiving-end system and the static voltage stability, and minimize the active transmission power loss. Then, the normalization and scalarization methods were implemented to solve the TOOM. In the second stage, the short circuit current level and cost-performance ratio were utilized as indices and the network structure was regulated based on the BPA software to ensure the safe and reliable operation.
