Abstract: Power load forecasting is the foundation of urban power grid planning, and saturated electricity power is a key indicator for determining the ultimate power grid scale when performing the urban power grid planning. Taken Hubei province as the empirical example, the saturated electricity power is studied by employing Logistic curve model in this paper. Firstly, the electricity power consumption and annual maximum power load of Hubei province are forecasted; then, the saturated time and scale are determined according to the judgment criteria of electricity power saturation. The calculation result shows the electricity power of Hubei province will reach saturation at 2042-2043, and the electricity power consumption and annual maximum power load will reach to 377.89 billion kWh and 66.2499 million kW, respectively.

Abstract: Distribution network equipment failure causes a serious impact on society. So a reasonable approach to reduce the consequences of equipment failure (ie, equipment failure affecting degrees) is necessary. This paper presents a comprehensive evaluation method which combines fault traversal, AHP-TOPSIS method to ensure the degree of different equipment failures. Meanwhile, in order to reduce the impact of equipment failure, a distributed power is accessed into distribution network, and we compared the impact value before and after it accessed. A numerical example shows that the distributed power can reduce the consequences of equipment failure as well as the grid and social impacts.

Abstract: In order to estimate and evaluate the blackout consequence in distribution network, a comprehensive evaluation index system including seven indexes was built, in which the blackouts loss for both users and power companies are fully considered. A comprehensive evaluation model based on AHP and improved grey clustering decision model was provided to evaluate the blackout consequence of different fault objects in distribution network. The improved GCDM model which can overcome the limitations of traditional whiten function, clustered different evaluation indexes and improved utilization of information and evaluation result. Finally, taking a distribution network as numerical example, AHP and improved GCDM model was implemented to evaluate and analyze the blackout consequences of different objects in distribution network. The results screen the differences in blackout consequence degree of fault objects effectively, indicating that this evaluation model is feasible and evaluation result can be referenced for power companies.
