Power grid dispatching operation real-time risk assessment method with equipment aging factors considered

Abstract

The invention discloses a power grid dispatching operation real-time risk assessment method with equipment aging factors considered. The method includes the steps that (1) the sequence of dispatching operation instructions to be operated is read, the dispatching operation states between the dispatching operation instructions in each step are determined, and meanwhile non-power information at the current moment is obtained, wherein the non-power information comprises the equipment operation information and the social state information; (2) expected fault scene sets of all the dispatching operation states are determined; (3) the real-time occurrence probability of each expected fault scene in the expected fault scene sets corresponding to all the dispatching operation states is calculated; (4) the load reduction quantity when the control expense for enabling the expected fault scenes to be recovered to a normal working state from a failure state is minimum is determined; (5) risk indexes under all the dispatching operation states are calculated; (6) risk control measures are formulated according to practical situations so as to guarantee normal execution of the sequence of the dispatching operation instructions, and the safe and stable operation capacity of power grids is improved easily.

Description

technical field [0001] The invention relates to the field of power grid dispatching operation, in particular to a real-time risk assessment method for power grid dispatching operation considering equipment aging factors. Background technique [0002] In order to ensure the safe, economical and reliable operation of the power grid, the dispatcher must take reasonable dispatching operation instructions. At present, the dispatcher mainly operates the power grid based on the real-time operation data of the power grid and personal experience. In practice, the scheduling operation instruction ticket is usually a scheduling operation instruction sequence, including several scheduling operation instructions, and the next instruction can be executed only after the previous scheduling operation instruction is normally executed. There is a dispatching operation state between two dispatching operation instructions, and factors such as bad weather and equipment failure during the execut...

AI Technical Summary

Problems solved by technology

There is a dispatching operation state between two dispatching operation instructions, and factors such as bad weather and equipment failure during the execution of the dispatching operation instruction may cause the risk level of the dispatching operation state to be too high, affecting the normal execution of the next dispatching operation instruction and threatening the system safe and stable operation

[0003] The current real-time risk assessment method for power grid operation security that has been put into use can only evaluate the established power grid operation mode, that is, the stable state of the power grid before or after the execution of a certain dispatch order ticket, and has not yet been able to evaluate the dispatch operation status in the dispatch operation order sequence Methodology for Risk Assessment
