Analysis on Security of Energy Networks Based on Current China’s Multiple Energy Situation

According to current China’s energy situation, multiple energy resources, autonomous and nonautonomous energy region and spatial distribution feature, we study network security by using n 2D lattices with multiple support-dependence relations, which are under random attack. The result suggests that lattice model becomes more robust and secure as the fraction of autonomous nodes increases. And, by decreasing the number of lattice networks, the multiple support-dependence network gets more secure. Interestingly, we find that the average supporting degree makes a significant impact on security for network composed of more than two networks, but for network composed of two networks, it has a little influence on the security. Therefore, by increasing the average supporting degree, energy network composed of more than two networks becomes more safer.
