With the increase of the UHV transmission line plan and construction, UHV power grid has become an important part of modem grid and brings much more challenges to the modern grid operation and control. The key technologies of the UHV power grid control and operation were outlined and summarized in this paper. Focusing on the aspects of the power flow control and optimization as well as the stability and control of the UHV power grid, the transfer capability, the operation of the electro-magnetic ring, the optimization of the reactive power flow, the research of the stability and control were also summarized and outlined in this paper. The technical problems which needed to be studied and solved were put forward. Besides, in order to provide reference for the planning, dispatching, operating and control of the UHV power grid, the technology trend and future direction in the aspects of operating and control about the UHVAC power grid were pointed out.
