Posterior probability locates faults under the influence of new energy resources

Energy is the power and foundation of social and economic development. The largest artificial real physical system is probably the modern power systems. And the operation of power system is near to limiting condition of its capacity. Under these circumstances, a minor fault may cause a series of extensive power failures. In this paper, posterior probability fault localization has been carried out by fully considering the intermittency and fluctuation of the access of new energies to power system. The results have confirmed that the posterior probability fault localization is accurate and reliable.
