Identification method of key transmission sections in power grid from the perspective of transient stability
The unreasonable selection of key transmission sections will increase the abnormal load of the power grid,thereby interfering with the stable operation of the power grid.Therefore,a method for identifying key transmission sections of the power grid from the perspective of transient stability is proposed.Based on the transient stability conditions,extract power grid characteristic information,and combine the electricity performance indicators to solve the transient stability model,completing the evaluation of the electricity performance of the power grid section from the perspective of transient stability.On this basis,define the key transmission cross-section,calculate risk assessment indicators,determine the value range of identification weight indicators,and complete the design of the identification method for the key transmission cross-section of the power grid from the perspective of transient stability.The experimental results indicate that under the application of the above identification methods,it can be ensured that the power grid load within the selected key transmission section does not exceed 5.2×1011 kW,effectively solving the problem of abnormal increase in power grid load caused by unreasonable selection of key transmission sections,can improve the stability of power grid operation.
