Flexible control method for demand side load

Abstract

The invention discloses a flexible control method for demand side load. The flexible control method for the demand side load includes that setting a demand side interaction load feedback model; flexibly controlling the demand side load based on the demand side interaction load feedback model. The flexible control method for the demand side load is capable of overcoming the disadvantages of bad power grid stability, low power supply reliability, bad user experience and the like of the prior art so as to realize the advantages of good power grid stability, high power supply reliability and good user experience.

Description

Technical field [0001] The present invention relates to the technical field of power energy saving, in particular to a demand side load flexible control method. Background technique [0002] The "Twelfth Five-Year Plan for Energy Development" recently issued by the State Council emphasizes "the development of interactive and intelligent electricity consumption, the implementation of dynamic electricity price management, guide users to use electricity, and allow users to participate in the interaction of supply and demand, so as to achieve large-scale peak reduction and valley filling, and reduce 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 efficiency of power resource utilization, improve power usage, and achieve scientific, economized, and orderly power usage, while increasing power supply, overall consideration and priority use of powe...

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
