Problems solved by technology

[0004] However, the main method of the demand-side load control technology in the existing technology is to realize Internetization, which is to link the dispatching with the user side. By receiving dispatching and sending instructions, the management system shuts down some electrical equipment according to the dispatching instructions to meet the regulatory requirements. Lack of more flexible and optimized load regulation means

Embodiment 1

[0040] Refer to attached figure 1 , a flexible load-based demand-side load regulation method provided in this embodiment includes the following steps:

[0041] S101. The dispatching system sends a load adjustment instruction to the flexible load management system;

[0042] The dispatching system can be the dispatching unit of the power grid or other enterprises with load control requirements. The flexible load management system is connected to the dispatching system through the public Internet, and the load adjustment instructions sent include the load adjustment amount in a certain area within a certain period of time. For example, at a certain time, Beijing issued a demand for load adjustment, requesting to reduce the load by 100KW between 1:00pm and 1:30pm on a certain day, and the Beijing dispatching system would send the flexible load system the From 00 to 1:30, the load adjustment instruction to reduce the 100KW load in the Beijing area.

[0043] S102. After receiving ...

Abstract

The invention discloses a flexible load based demand side load control method and system. The method comprises the following steps of acquiring load total quantity and power utilization information of a user under a region before adjustment after a flexible load management system receives a load adjustment instruction; automatically generating a load control strategy according to the power utilization information of the user and a user participation priority; generating a control instruction and sending the control instruction to a participating load control device; receiving the control instruction and executing control action by the load control device; and adjusting again when difference between the load total quantity before adjustment and the load total quantity after adjustment is smaller than the required load adjustment quantity. Through the above technical scheme, rapid adjustment on the demand side load is achieved; with the arrangement of the user participation priority, the intention of participating in load dispatching of the user can be reflected better, and the demand side load control is more reasonably executed.

Description

technical field [0001] The invention relates to the field of control, in particular to a demand-side load regulation method and system based on flexible loads. Background technique [0002] With the rapid economic development of our country and the influence of economic structural adjustment and other factors, the power consumption structure and the supply and demand situation are constantly changing. The proportion of electricity consumption by the tertiary industry and residents’ daily life is gradually increasing. The contradiction between power supply and demand has become increasingly apparent. increase, the peak-to-valley difference increases, and the requirements for power supply reliability continue to increase. [0003] After the development of the first phase of DSM and the second phase of DR, since 2007, the power DSM has been endowed with new connotations on the traditional basis, mainly including automatic DR technology, intelligent and orderly power consumption...
