Embodiment Construction

[0055] Below by calculation example, the technical scheme of the present invention is described in further detail:

[0056] The method comprises the steps of:

[0057] Step 1: The control center determines the demand response optimization target according to the control needs, and calculates the air-conditioning load demand response volume;

[0058] Step 2: The control center predicts the temperature at the next moment according to the operating status, parameters and outdoor temperature of the air conditioner load, calculates the virtual temperature, and arranges the optimization sequence in descending order;

[0059] Step 3: The control center organizes the demand response and the virtual temperature serial numbers of each air-conditioning load to form a control signal, and sends them to the corresponding air-conditioning load controllers;

[0060] Step 4: The air-conditioning load controller calculates and adjusts the operating state of the air-conditioning load using the ...

Abstract

The invention discloses an air conditioner load cluster distribution type control method based on Lyapunov optimization. Through the Lyapunov optimization algorithm, the temperature of an air conditioner load is processed, and through distribution type optimization control, the control effect of an air conditioner load cluster under a non-ideal environment is enhanced. By adopting the technical scheme, the computational burden of a central control center is relieved; the communication volume between the control center and a user is reduced; the control effect of air conditioner load demand response under the non-ideal communication condition is improved; the situation that a centralized control algorithm frequently obtains the running state of the user is avoided; violation of privacy of the user is reduced; and the temperature comfort of the user is guaranteed, meanwhile, the weight relation of the temperature comfort of the user and an optimization target is adjusted, and the air conditioner load is flexibly controlled.

Description

technical field [0001] The invention is a distributed control method of air conditioner load group based on Lyapunov optimization, which is used for smoothing the load fluctuation of the power system and belongs to the technical field of demand response control of the power system. Background technique [0002] The current rapid development of communication and other technologies provides a basis for small and medium-sized loads to participate in demand response. The air-conditioning load has good energy storage characteristics and a large quantity base, making it the preferred object of demand response control. At present, there have been many researches on air-conditioning load participation demand response, but most of them belong to centralized control methods. This control method has high requirements on communication quality. Less effective, sometimes even unresponsive. Therefore, how to effectively reduce the impact of non-ideal communication on the control effect o...
