As the urgency of grid dispatching operation to a grasp of future state security change is becoming increasingly important,an on-line trend analysis technology with operation mode arrangement for large power grid is proposed by referring to the development of intelligent dispatching support system and its dynamic security assessment technology.Based on the current operation mode of the power grid and on-line stability conclusion aided by dispatch operation adj ustment,dispatch scheduling,the data of new energy and load forecast is used to form the estimated power flow in a future moment.And the future security states and trend are rapidly assessed,with the auxiliary decision-making method for control given.This technology has been applied in Central China power grid and Heilongjiang power grid,providing technical support to pre-control methods of complex power grid dispatching operation and promoting power grid control transformation from empirical to intelligent.
