Description
Summary:In order to identify the critical edges in the grid more accurately, this paper synthesizes the structural vulnerability and state vulnerability of the grid to evaluate the grid edges comprehensively. Combining the improved power flow betweenness, weighted power flow transfer entropy, and variance loading ratio, the importance weighting metric of the grid edges is proposed, and the critical edges in the grid are obtained by rationally setting the optimal weights. Through simulation tests on the IEEE 39-node system, the top ten edges with comprehensive weighted values in the system are obtained, and the validity of the proposed comprehensive weighting metric is verified under different attacks.
