The Impact

Owing to more and more people concern about environment issues and reduction of fossil fuels, a growing number of distributed generations (DGs) are being interconnected to the power system. The active distribution network (ADN) provides an effective way to achieve the large scale connection and efficient utilization of them. This paper analyzes the vulnerability performance of active distribution network quantitatively and discusses the impact of DGs on the distribution network transmission efficiency under different grid structure through the application of complex network theory in power system. The example results show that meshed network structure can effectively promoting the consumption of DG and verify the feasibility of applying complex network theory to the distribution network for vulnerability analysis.

Complex Network Theory

As further development on the applications of CN (complex network) theory, evaluation of transmission line vulnerability requires the consideration of physical attributes of power system, instead of simply considering its topology features, which helps to deduce more precise predictions for the stability of power system. This paper introduces a novel and efficient evaluation method based on CN theory to evaluate influence of line faults to the static stability of power system, comprehensively considering the factors of system load level, power capacity utilization rate of transmission lines and worldlet features. The method is illustrated in the IEEE118 bus system.

Regional Vulnerability

Cascading failure of network features in power system is analyzed in this paper using complex network theory and method, and Central China power grid are analyzed in detail on the three kinds of attack forms (maximum load, the most generous attack and random attack) of regional vulnerability. It provides technical means for the prevention of cascading failure .
