Inverter air conditioner aggregate control method for demand response

Abstract

The invention discloses a demand response-oriented variable frequency air conditioner aggregation control method. The method comprises the following steps: establishing an electrical parameter model of a variable frequency air conditioner; establishing a thermal parameter model of the variable frequency air conditioner; establishing a virtual energy storage model of the variable frequency air conditioner; proposing to obtain a temperature maintenance strategy; proposing a control strategy of VSOC priority; and proposing a linear recovery strategy. According to the method, a variable frequencyair conditioner load virtual energy storage model which is more beneficial to practical application and a corresponding variable frequency air conditioner control strategy are provided, so that the power of the is reduced to the power when the temperature is kept unchanged, and the purpose of meeting the power shortage as far as possible under the condition of ensuring the comfort degree is achieved.

Description

technical field [0001] The invention relates to the field of air conditioner load demand response, mainly including alleviating the tense situation of supply and demand, enhancing the system's ability to cope with power flow fluctuations, improving system operating efficiency, and promoting energy saving and emission reduction. More specifically, it relates to a demand response-oriented frequency conversion Conditioning aggregation control method. Background technique [0002] With the global consensus on preventing global warming and promoting sustainable development, the penetration rate of renewable energy generation in the power system is increasing rapidly. The intermittent and random nature of renewable energy sources such as wind and solar makes it more difficult and expensive for the electricity system to maintain a balance between supply and demand. The relative share decline of traditional generators (such as thermal power units and hydroelectric power units) redu...

Problems solved by technology

At present, the operation and scheduling technology of air conditioners started relatively late, and there is no discussion on the participation of frequency conversion air conditioners in power regulation. Therefore, the key technologies of frequency conversion air conditioner load modeling, operation control and effect evaluation are studied, and the key technologies for improving energy utilization efficiency and participating in peak shaving and filling are fully explored. It is of great significance to the sustainable utilization of energy and the development of a green and low-carbon society in my country to ensure the efficient and safe operation of the power system.

On the other hand, most of the air-conditioning loads form load peaks, and the huge air-conditioning load has brought a great negative impact on the safe and economic operation of the power grid, and the load of small split air conditioners is random and dynamic due to user habits and other reasons. Sexuality and other characteristics, resulting in aggravation of load fluctuations

The equivalent thermal parameter model (equivalent thermal parameter, ETP), which is the basis of control theory, is widely used, but it simply equates electric energy to a constant power input, lacks in-depth analysis of electric energy parameters, and cannot feedback the load status of air conditioners Impact of Changes on the Grid
