Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0032] The multi-type elastic loads in the present invention include the following five types: air conditioners, heat pumps, electric water heaters, energy storage, and electric vehicles.

[0033] One, the elastic load model that the present invention adopts

[0034] air conditioner:

[0035] When the air conditioner is running, it has the characteristics of periodic work. The indoor temperature fluctuates around a certain temperature setting value. When the air conditioner in the cooling state is turned on, the temperature in the room continues to drop. When the temperature change reaches the lower limit of the boundary temperature θ - , the air conditioner is turned off; when ...

Abstract

The invention discloses a multi-type power elastic load combined adjustment method in building groups. The method comprises steps of firstly determining an optimization target curve of a regulation and control quantity according to the adjustable potential of elastic loads in a range under the jurisdiction of a dispatching center or an aggregator; formulating a global optimization target of regulation and control; determining a load group participating in regulation and control according to use characteristics of the loads in the full time domain range, the power consumption behavior prediction result and the like; grouping the loads according to the load characteristics, and sorting the adjustment sequence of each group according to scene requirements; starting to adjust the adjustable resources in the group from the first group, and if an optimization target is achieved, ending regulation. The method is advantaged in that different elastic loads are grouped, the adjusting effect of demand response is improved, moreover, loads with the state values far away from the target value are preferentially selected for regulation and control based on sorting of the states of the elastic loads.

Description

technical field [0001] The invention relates to the field of load adjustment, in particular to a method for joint adjustment of multiple types of electric elastic loads in a building group. Background technique [0002] The development of domestic power demand response projects has just started and lacks experience. In the study of elastic loads of buildings participating in power demand response, a large number of control strategies for single types of loads have been studied, such as research results on demand response strategies for single elastic loads such as air conditioners, electric vehicles, and water heaters. Different types of loads have different characteristics, fully exploiting and utilizing the characteristics of elastic loads can further improve the energy efficiency of system operation and reduce users' perception of elastic loads. [0003] The traditional technology has the following technical problems: [0004] At present, there is no research on the str...
