Embodiment 1

[0074] The invention considers the user's power consumption comfort and optimizes the power consumption strategy of a single residential user. Firstly, preprocess the original electricity consumption data of residents, and use the K-means clustering method to extract the typical daily electricity consumption curve of users. Then analyze the working characteristics of household electrical equipment, establish its mathematical model and corresponding constraints; establish a correlation matrix according to the relationship between electrical equipment, adjust the operating period parameters of schedulable loads, and establish a model of user comfort with electricity. Finally, a multi-objective optimization model considering user comfort and load peak-to-valley difference is established, and a genetic algorithm is used to solve the model.

Abstract

According to the technical scheme provided by the invention, a resident user multi-objective optimization power utilization strategy based on data mining comprises the steps of obtaining original power utilization data of resident users; extracting a typical daily power consumption curve of the user from the data, and analyzing power consumption characteristics of the user; establishing a multi-target power utilization model based on the power utilization characteristics; solving the multi-target power utilization model by adopting a genetic algorithm to obtain an optimal power utilization strategy which ensures the power utilization comfort of the user and effectively reduces the power utilization peak-valley difference. According to the technical scheme provided by the invention, the peak-valley difference is reduced while the power utilization comfort of a user is effectively ensured, power generation and power utilization tend to be balanced, and the power supply pressure of a power utilization peak is reduced, so that the problems that the power utilization load is continuously increased, the reliable operation of a power grid is greatly influenced and the peak-valley difference is increased are solved.

Description

technical field [0001] The invention relates to the field of electric power demand response, in particular to a data mining-based multi-objective optimization electricity consumption strategy and system for residential users. Background technique [0002] At present, with the proposal and continuous advancement of the smart grid process, many information systems and platforms are effectively managing various smart devices to promote smart grid construction and improve the company's grid operation and management level.
