Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] This patent provides a load modeling and operation control method for inverter air conditioners based on demand response. The purpose is to directly control the temperature and compressor power of inverter air conditioners, and on this basis to dynamically optimize and regulate the inverter air conditioners. Reduce the inverter air conditioner load during the summer peak period, ensure the completion of the power grid dispatching target, reduce the impact of air conditioner load control on human comfort, make full and reasonable use of the inverter room air conditioner group, and further enrich the existing demand response resources.

[0044] The load modeling and operation control method of variable frequency air conditioner based on demand response includes the following steps:

[0045] (1) Establish the load model of the inverter air conditioner and the inverte...

Abstract

The invention discloses a variable-frequency air conditioner load modeling and operation controlling method based on demand responses. According to the variable-frequency air conditioner load modeling and operation controlling method based on the demand responses, the set temperature and the set compressor power of variable-frequency air conditioners are directly controlled, and dynamic optimization control over a variable-frequency air conditioner group is conducted based on the control over the set temperature and the set compressor power; in this way, the load of variable-frequency air conditioners is lowered in the summer peak period, and it is guaranteed that a power grid dispatching purpose is completed; the influence of the control over the load of the air conditioners on the comfortable degree of human bodies is lowered, the variable-frequency room air conditioner group is fully and reasonably utilized; and existing demand response resources are further enriched.

Description

technical field [0001] The invention relates to the technical field of electric power systems and automation thereof. More precisely, the invention relates to a load modeling and operation control method implemented on variable frequency air conditioners in a smart grid environment. Background technique [0002] According to statistics, the air-conditioning load during the peak load period in summer accounts for 30%-40% of the peak load, and even reaches about 50% in Beijing, Shanghai and other cities. The huge air-conditioning load has become an important reason for the continuous increase of peak load and the continuous deterioration of load characteristics. , which has a great negative impact on the safe and economic operation of the power grid. At the same time, the building environment to which the air-conditioning load belongs has a certain heat storage capacity. Through reasonable load control methods, the air-conditioning system group after centralized control can no...
