Embodiment
[0200] Based on the IEEE14 node system, the AC-DC hybrid system is constructed, and the AC line between the AC nodes 4 and 5 of the original system is replaced with a double-terminal DC transmission system, and the constructed AC-DC hybrid system is guaranteed to have the same characteristics as the original AC system. Same current situation. Among them, the converter station connected to node 5 is the rectification side, and the converter station connected to node 4 is the inverter side. The improved IEEE14 node system is as follows: image 3 shown.
[0201] The effectiveness of the present invention is illustrated by comparing the attack results and scheduling costs under no attack (scheme 1), optimal attack without considering commutation failure (scheme 2), and optimal attack (scheme 3) considering commutation failure, The results obtained through simulation are shown in the table below:
