With the cross regional interconnection of the power grid, it is more and more inconsistent with the actual development of the power grid to use a single sandpile to simulate the power grid. The multi-sandpile model is developed to simulate the evolution process of the whole power grid failure in the form of all the single sandpiles evolving synchronously. First of all, the modeling method of multi-sandpile...
According to the application of cellular automata theory in complex system, a new kind of cellular automata model of grid failure is proposed which starts from basic concept of cellular automata and defines the composition method of cell, cellular rules and neighbors and so on. By simulation of the model, it is able to get the evolution of grid failure and it comprehensively considers of structural...
In this paper, the risk measurement and early warning of future power blackouts are carried out, from the angle of the lost load. Based on the entropy theory which is used to characterize the degree of power blackouts, this paper proposes a lost load forecasting model based on maximum entropy, and uses the Gansu power grid to calculate and analyze the proposed model. The example shows that the proposed...
This paper employs the extended BLT equation to analyze the terminal response of lossy microstrip line illuminated by a plane wave. The paper yields the equivalent transmission line model of microstrip line by analyzing its distribution parameters. By treating the electromagnetic field coupling path as “tube” and considering coupled and scattered components of microstrip line, the paper advances original...
