Vulnerability analysis of power grid based on multi-agent complex systems

Modern power grid is a typical multi-level complex giant system. The conventional analytical methods based on reductionism can´t provide sufficient guidance for its operation and management. Complex system theory, based on holism, has its specific advantages in power grid´s research. But, it has some limitations. In this article, we improve complex grid by introducing new parameters which can describe the grid´s characters better and using multi-agent theory. As an application, the complex power grid constructed with actual data from North China grid is constructed and its vulnerability has been simulated and analyzed under different attacks.
