Analysis Method of Factors Affecting the Settlement of Large Power Users

In order to improve the access scheme for large users in the grid planning and ameliorate the service quality of power companies for access to large users. The main factors affecting the settlement of large and medium-sized enterprises were the first studied in this article. From the perspective of power grid, a relatively comprehensive system of influencing factors for large user settlement was constructed which integrates power grid factors and non-power grid factors such as economy, market and traffic. Next, the improved principal component analysis method was used to determine the principal components and calculate the amount of information contained in each secondary index, and the index was screened and replaced according to the amount of information. After that, considering the influence of the time effect, the improved gray correlation model is used to analyze the correlation between each influencing factor and the number of large users settlement. Then, the weight value and influence proportion of the primary index were calculated by integrating the amount of information contained in the secondary index and its correlation degree. According to the influence proportion value, the influence degree of power grid factors on the settlement of large users was determined, and the power grid planning was adjusted according to the correlation degree of the index. Finally, a case was taken to verify that the method proposed in this paper can strengthen the adaptability of the power grid to large users, improve the energy consumption experience of large users and the overall attractiveness of the city.
