Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] Such as figure 1 As shown, it is a flow chart of the present invention, and the demand response user automatic screening method includes the following steps:

[0045] Step 1: Select a part of users from the remaining responding users as candidate users for this round of screening, and then establish an integer linear programming model based on the power load gap and the load reduction capabilities of candidate users; specifically, the following steps are included:

[0046] S11: According to the performance of demand response users in previous participation in demand response, sort the remaining demand response users from good to bad according to certain rules;

[0047] S12: Select the top N after sorting candidate users as candidates for this round of screening, the calculation formula is shown in formula (1):

[0048]

[0049] Among them, L is the total n...

Abstract

The invention discloses a method for automatically sorting demand response users. Some users are selected from remaining response users as candidate sorting users of the round, and an integer linear planning model is established according to power load gap and load reduction capability of the candidate users. The solution is obtained through the branch and bound method to interact with users. Whether a next round of sorting is necessarily is determined according to feedback, and process is repeated until the power load gap defined by an upper-level system is met. The method adheres to the sorting principles of fairness, higher priority with higher creditability and maximally approaching the power load gap, and flexible interaction with power users and multiple rounds of dynamic sorting ensure matching level with the power load gap. Users are fairly selected to participate in demand response, the power user participation is improved, and the risk that real response capacity can not satisfy the expected power load gap capacity is reduced.

Description

technical field [0001] The invention relates to a demand response user automatic screening method, which belongs to the technical field of intelligent electricity utilization in electric power systems. Background technique [0002] Demand response means that when the wholesale spot price in the electricity market rises or the reliability of the system is threatened, power users respond to economic incentive policies such as electricity prices of power supply companies, guide users to adjust power consumption patterns, and transfer part of the power load to the low-peak period of the grid to ensure grid power. Balanced mechanics. [0003] With the introduction of demand response, for the user side, while improving the efficiency of electricity consumption, the user can also obtain electricity fee reduction or incentive payment; for power grid dispatching, through demand response peak shaving, the load curve of the power grid is improved, and the power grid load curve is avoid...
