Problems solved by technology

Traditional demand response signals mainly rely on manual transmission, and personnel manually shut down equipment or adjust the operating power of equipment, which makes it impossible for the user side to obtain DR information on the grid side in time, and the grid side cannot adjust DR signals in real time based on the latest power consumption information of users , which reduces the reliability and efficiency of DR to achieve peak shaving and valley filling
Therefore, it is difficult for the traditional demand response to truly realize the peak-shaving and valley-filling of the power grid and ensure the balance between supply and demand of the power grid.

Embodiment Construction

[0046] The technical scheme of the present invention will be further described below in conjunction with the drawings.

[0047] figure 1 It shows a flow chart of schedulable strategies that take into account the willingness of users to actively participate in response to increase the load rate of grid operation. Participants include dispatch centers, smart home appliances and users. As shown in the figure, when entering the DR scheduling time interval proposed by the present invention [t DRa , T DRb ], first of all the current total power of all appliances P total And power limit P limit The size is compared and judged. When P total > P limit Calculate the comfort index K value according to the real-time data feedback of the home appliances, and determine whether to switch the status of the corresponding home appliances in the ascending order of the K value. If the appliance is powered on, power off and update P total ; If the appliance is in a power-off state, the next a...

Abstract

The invention provides a demand response method considering user real-time comfort and a power grid load rate. Different from a passive control terminal in the traditional sense, the method considersa schedulable strategy of actively participating in response to improve the operation load rate of the power grid by integrating the will of a user. Firstly, household appliances of the user are classified, types of the intelligent household electrical appliances are determined, the comfort index of the user is calculated based on operation characteristics, a working state and the external environment information of the intelligent household electrical appliances, a power grid power scheduling limit value is set according to the power grid load rate improvement demand, and finally the comfortindex of the user is updated in real time to realize demand response control of the intelligent household electrical appliances. The method is advantaged in that the comfort level of the user is ensured, and the operation load rate of the power grid can be effectively improved.

Description

Technical field [0001] The invention relates to a demand response control method, which belongs to the technical field of demand response intelligent control, and in particular relates to a demand response method that considers user real-time comfort and grid load rate. Background technique [0002] The load rate refers to the ratio of the average active load to the highest active load of the power grid, that is, the percentage of the ratio of the level of active load to the highest active load of electricity in a period of time. The general formula is [0003] [0004] In the formula: λ—load rate; P max —The maximum active load in the statistical period; t 1 ,t 2 —Start time and end time of the statistical period; P(t)—power function with respect to t. [0005] Due to the rapid development of power grids in recent years, the peak-to-valley difference in power load has been increasing, and the load rate of power consumption has gradually decreased, making it increasingly difficult f...
