Problems solved by technology

At the same time, a demand response system can only support one or several power load control methods, and the scalability level of the system varies. Once the response mode and implementation method change, the original system needs to be greatly modified.

Embodiment

[0064] exist figure 2 In , it is assumed that the demand response center of the power company is responsible for the power consumption management of 1000 households in each of the two communities. The secondary collection and control equipment includes two communities each with a user energy efficiency system and the SCADA equipment deployed by the power company in the two communities. It can also realize the control of some specific user equipment through the connected intelligent controllers, while SCADA equipment can only collect the load information of lines and transformers, and the control can only reach the level of lines and transformers. The first-level collection and control equipment includes intelligent controllers for some consumer electrical equipment (such as air-conditioning intelligent controllers) connected to the user energy efficiency system in the two communities, which can realize the control of specific consumer electrical equipment. The demand respons...

Abstract

The invention relates to a flexible adaptive power load control system and a control method thereof. The system is sequentially connected to electric equipment of a user via secondary collecting control equipment and a primary collecting control equipment by a demand response center and establishes connections and feedback with various types of user terminal equipment in the demand response center through cloud equipment and the Internet; in addition, the user reserves control capability for equipment of the user. For the control method of the system, according to power demand, user equipment condition, intentions of users and the like, various control schemes based on electricity price, based on incentive mechanism, in a full automatic mode, in a full manual mode, etc. can be adopted flexibly. The invention provides an adaptive control system architecture supporting various demand response modes, with high flexibility and expansion convenience; the control system facilitates the achievement of a demand response system and improvement of system stability.

Description

technical field [0001] The invention belongs to the field of electric power systems and automation thereof, and relates to a flexible self-adaptive power load control system and a control method thereof. Background technique [0002] The energy issue is a major challenge facing human society in the 21st century. On the one hand, with the development of human economy and society, the demand for energy continues to increase; on the other hand, the earth's fossil energy is also increasingly showing its limitations, requiring human beings to constantly search for new energy sources. [0003] Electricity is the main form of energy used in countries around the world today. In the traditional power system, the load of power users is often passive, and the control method is also "hard". When the load exceeds the power supply capacity, the load can only be disconnected by means of "power cut off" and "orderly power consumption". [0004] Modern power systems have various control r...
