UPFC can distribute the line transmission power rationally and improve the stability of power grid operation, which is not only the focus of the current attention of the engineering community, but also the hot spot in the academic field. Aiming at the application of UPFC in UHV power grid, this paper first introduces UPFC’s principle and function. Based on the analysis of the problems in UHV power grid planning, this paper proposes the UPFC application scenarios in UPFC power grid. Then using BPA simulation platform, this paper calculates and analyzes the feasibility of each UPFC alternative location in different scenarios. Finally, based on the fuzzy evaluation, the comprehensive evaluation of each scheme in technical level is carried out. The results show that UPFC has strong capability in improving the transmission capability and improving the system voltage, which can solve the problems that UHV Power Grid will face effectively.
