Risk Assessment Model and Method of Urban Distribution Network Considering Real-time and Potential Factors
Authors: , , , , ,
Abstract: In order to make accurate assessment of the risk level of urban distribution network, this paper establishes the risk assessment model of distribution network and proposes a risk assessment method. The risk assessment model of distribution network is established in two aspects, which are operation risk and grid risk. Operation risk reflects the risk level of the current operation state of the distribution network, while grid risk reflects the potential risks resulting from defects of the grid structure. Then the corresponding risk assessment index system of distribution network is established, and the risk quantized values and risk rating are calculated according to the index values. The comprehensive risk level of distribution network is figured out based on the above calculation results, and variable weights and logarithm compound method are used in the process of calculation. Finally, a numerical example shows that the proposed risk assessment model is feasible and the risk assessment method is effective. The proposed risk assessment model has been adopted by Shenzhen Power Supply Bureau of China Southern Power Grid, and the application effect is good.
