Description

technical field [0001] The invention relates to the technical field of electric power saving, in particular to a method for flexible control of demand-side loads. Background technique [0002] The "Twelfth Five-Year Plan for Energy Development" recently issued by the State Council emphasizes "developing interactive and intelligent electricity consumption, implementing dynamic management of electricity prices, guiding users to use electricity, allowing users to participate in the interaction between supply and demand, and realizing large-scale peak-shaving and valley-filling, reducing System reserve capacity to ensure smooth power output and safe and reliable operation of the system" is an important aspect of the future development of smart grids. In order to improve the utilization efficiency of power resources, improve the way of power consumption, and realize the scientific, economical and orderly use of power, while increasing power supply, overall consideration and prior...

Problems solved by technology

[0003] In power system demand-side load management, load shaping through economic and technical measures is the basic content of demand-side load management. There are many studies in this area, and the theory is becoming more and more mature; The load has the characteristics of geographical dispersion, various types, complex structure, and nonlinearity. The classification and synthesis of loads have become a difficult problem in demand-side load management, and there is a lack of effective flexible control technology for various loads in the power grid.

In the existing demand-side load management research, the way of classifying loads only by electricity price category is too rough, there is no systematic classification and integration of loads, the establishment of a linear programming mathematical model, and the optimal control strategy is obtained by solving; or only Technical measures and economic measures for classification and sub-item, without systematic process feedback management for demand-side load flexible control, cannot effectively guide users to implement management to alleviate the gap between power demand and supply, reduce grid peak-shaving costs, and improve power supply reliability. It has no significant effect on improving the efficiency of terminal power consumption

[0004] In the process of realizing the present invention, the inventors found that there are at least defects in the prior art such as poor grid stability, low power supply reliability, and poor user experience
