— The urban power network planning is the premise of the power grid construction, so more and more attention has been paid to its scientific nature and rationality. However, the multifarious risks in the urban power network planning have become the barriers of the city power grid development. Hence, it is extremely important to identify these risk factors. In this paper, we proposed an improved risk matrix algorithm innovatively. Then, it was applied to assess the risk of XX city’s power network planning. In this algorithm, the conventional two-dimensional risk matrix has been reshaped by adding two more dimensional characteristics, including the risk rating and the risk’s attention rating. Based on this four-dimensional risk matrix, the Borda method is used to calculate the sequence value of each risk factor, then we can use these sequence values to construct the judgment matrix by using AHP method so as to calculate the weight of the risk factors and then identify a couple of important risk factors that have great impact on the urban power network planning. Finally, some corresponding advices of risk aversion are proposed to guarantee the smooth operation of urban power network planning.
