Abstract

Abstract: Due to the lack of guide tools for UPFC real-time operation optimization, the powerful power flow control capability of UPFC cannot be played flexibly. An UPFC operation optimization decision-making application function is designed based on the smart grid dispatching control system. According to the power flow calculation characteristics of UPFC project under actual quota working mode, the sensitivity of the UPFC control measures is solved. Parallel computing of the UPFC multi-control target set is carried out using the rich online computing resources, and the UPFC static security control measures and power flow optimization control measures are obtained. The designed application function makes full use of the UPFC control capability to improve the flexibility of power grid operation, and provides decision-making support for dispatching operators. The calculation process for UPFC online operation optimization is illustrated through a case study of the 500 kV UPFC project of Suzhou southern power grid. The results show that the proposed method can effectively solve the static security problem of the region near UPFC and optimize the near region network loss.

Key words: smart grid, dispatching and control system, unified power flow controller, static security, power flow optimization, cluster computing
