The practice of urban power network planning in China is facing more and more complex risks. The nature of the risks themselves is unclear and uncertain. In order to ensure that urban power networks are planned in a scientific manner, a reasonable risk assessment needs to be performed. Based on extension analysis and the matter-element extension theory, a model of risk evaluation designed to be applied to urban power network planning is put forward in this paper. This model ha:; the advantage that it conveniently quantifies the qualitative indices. At the same time, it also overcomes the main limitation of the matter-element method, namely, that if the risk index exceeds the risk grading standard, it can not be calculated using the correlation function. Finally, taking a specific urban power network as an example, the empirical analysis results show that this model is credible and practical. (C) 2011 Elsevier Ltd. All rights reserved.
