A load emergency control power grid simulation method and device for dealing with DC blocking

Abstract

A load emergency control power grid simulation method and device for dealing with DC blocking, the method obtains the power flow information of the DC line in the actual power grid and the state information of the precise load shedding device on the DC line, and according to the power flow information of the DC line in the power grid And the status information of the precise load shedding device on the DC line, in the event of a DC blocking fault, load reduction is performed on the specified load in the power grid simulation system. The load emergency control power grid simulation method and device provided by the present invention fully consider the operating state of the precise load shedding device configured with the DC line and whether the DC line meets the DC blocking fault condition, and can accurately and efficiently complete load shedding in the power grid simulation system , comprehensively and truly respond to the impact of precise load shedding device actions on the power grid.

Description

technical field [0001] The invention relates to the technical field of power grid system simulation, in particular to a load emergency control power grid simulation method for DC blocking. Background technique [0002] With the improvement of social production level, the stable operation of power grid has become a necessary factor for the development of social life. With the expansion of the grid scale, when any DC line in the grid fails, it will also have an impact on the operation of the entire grid; therefore, how to improve the emergency response capability of the grid fault has become the goal of experts and scholars. [0003] At present, the commonly used methods include measures such as DC boosting and pump cut-off in pumped-storage power stations, but the above-mentioned measures are still insufficient in the face of serious DC faults, and emergency load shedding measures are still necessary. With the gradual establishment of the market mechanism and incentive compe...
