Big consumer power supply access decision-making method considering load characteristic

Abstract

The invention relates to a big consumer power supply access decision-making method considering load characteristic. The big consumer power supply access decision-making method comprises the steps of defining installation reporting parameters of a big consumer according to electrical equipment information provided in installation reporting of the big consumer; forming an excavating load sample dataon the basis of normalization by virtue of the access big consumer historical power utilization data; clustering the load sample data into an L cluster through a fuzzy C mean value clustering algorithm, wherein the clustering center is the big consumer load characteristic library, and determining the type of the sample data according to the maximum membership principle; defining the load characteristic index according to the installation reporting parameters provided by the big consumer, and processing the load sample data according to the load characteristic index to form a training data set; based on the training data set, excavating a load pattern recognition rule of the big consumer through a classification and regression tree (CART) algorithm; and inputting a load recognition resultinto a big consumer power supply access combination and optimization model, and obtaining a power supply access optimization strategy through optimizing.

Description

technical field [0001] The invention belongs to the field of power system planning, and relates to the establishment of power supply access schemes, load classification and identification of load patterns of new access users. Background technique [0002] With the rapid development of the national economy, the power consumption of large users is increasing day by day. It is an important task for power grid enterprises to provide economical and reliable power supply paths for different types of large user loads. As the core link for large users to optimize their access to the power grid, business expansion and installation is the core link. The content is that grid companies accept applications for new installations and capacity expansion, and formulate power supply access plans according to the power supply capacity of the grid. Users who need new installations Connect to the network [1] . [0003] Business expansion equipment is the window of power grid enterprises. The f...

Problems solved by technology

The lack of this information can easily lead to the centralized connection of loads with relatively concentrated distribution of peak loads in a certain period of time, resulting in a continuous increase in the load peak-to-valley difference, and easy to touch the transmission capacity limit of power supply and distribution facilities during peak load periods. A series of problems such as low utilization rate of power supply and distribution facilities, waste of capacity, and poor economy

However, in the past business expansion and installation business, the information provided by large users was limited to the type of industry and the list of electrical equipment, which made it impossible for power companies to further grasp the time-domain distribution characteristics of large user loads
