Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings.

[0054] The power-saving potential of the inverter air conditioner changes with the control time, and it has little impact on the user to run the compressor at the lowest power in a very short time (second level). However, as the control time increases, this method cannot maintain the corresponding comfort in the air-conditioned room. For multiple air conditioners, the energy-saving potential should be calculated through the coordinated control within the group within the appropriate room temperature adjustment range.

[0055] This aspect provides a power-saving potential evaluation and load group aggregation method for variable frequency air conditioner loads participating in demand response. The potential evaluation model provides a reference for the power grid dispatching department to formulate the load dispatching target of the inverter air conditioner; at the sam...

Abstract

The invention discloses a method for electricity-saving potential estimation on load involved demand response and load grouping aggregation of variable-frequency air conditioners. Based on load modeling of the variable-frequency air conditioners, an electricity-saving potential estimation model of the load involved demand response of the variable-frequency air conditioners is established according to the comfortable degree of human bodies, and a reference is provided for a variable-frequency air conditioner load dispatching objective formulated by the power grid dispatching department. Meanwhile, the corresponding method for the load grouping aggregation of an air conditioner group is provided, accordingly the total load of the air conditioner group can be scientifically and effectively kept as the dispatching objective stably, and finally the energy-saving and emission-reduction work of resources on the demand side is promoted.

Description

technical field [0001] The invention belongs to electric power system and automation technology thereof. More precisely, the invention relates to a method for evaluating power-saving potential of variable-frequency air-conditioning loads in a smart grid environment. Background technique [0002] According to statistics, about 98% of air conditioners in developed countries such as Japan, Europe and the United States are inverter air conditioners. At the same time, inverter air conditioners are also gaining popularity in my country's sales market, becoming the mainstream in the field of air conditioners. However, unlike ordinary air conditioners, inverter air conditioners will continue to run after starting up and the energy efficiency ratio will change at any time. The existing load potential assessment and load aggregation methods are no longer applicable. At present, the application of air conditioner load participation in demand response is still in its infancy in China, ...
