The invention relates to a power grid future operation trend estimation method and system based on power flow parameters. The method comprises the steps of collecting the current power grid power flowdata and the data corresponding to factors having influences on a current power grid; inputting the collected data into a pre-built relation model between historical power grid power flow and influence factors, and estimating the future operation trend of the power grid, wherein the relation model between the historical power grid power flow and the influence factors comprises the historical power grid power flow data weight occupied by the key characteristics. According to the invention, the influence of various uncertain factors on the safety and stability analysis conclusion in the power grid operation situation change process is analyzed, the key characteristics of uncertain information such as new energy power generation fluctuation, bus load prediction errors and scheduling plan abnormity are extracted, a power grid future operation trend power flow parameter estimation method considering uncertainty is studied, and a power grid operation trend data online forming technology comprehensively considering operation situation uncertainty and a control strategy is studied.
