Problems solved by technology

[0004] The traditional three-phase unbalance control of distribution network is usually achieved by controlling new energy sources, manually adjusting the load phase, and adding voltage control devices. There is no strategy for using demand response resources to control the three-phase unbalance of distribution network.

Embodiment Construction

[0089] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0090] The present invention is a method for controlling the three-phase imbalance and carbon emission of a demand-response participation distribution network, and its specific steps are as follows:

[0091] S1. First, forecast the load and output of new energy.

[0092] (1.1) Load prediction based on total power data of household users. The steps are as follows: first, the power data processing of the user at one point per hour per day is performed, and the mean value of the time before and after the missing value is selected to fill the missing value, and the data is normalized. The data normalization formula is as follows:

[0093]

[0094] where X norm is the normalized value, X is the current value, X max is the maximum value in the data, X min is the smallest value in the data.

Abstract

The invention discloses a demand response participated power distribution network three-phase imbalance and carbon emission treatment method. The method comprises the following steps of performing day-ahead load and new energy output prediction; simulating user behaviors to form flexible load power data, and obtaining a user basic load on the basis of the predicted user total load; a flexible load model of the electric vehicle and the air conditioner is constructed by considering load operation condition constraints; constructing a three-phase imbalance index of the power distribution network, and constructing a carbon emission index of the power distribution network based on different energy carbon emission factors; a multi-target optimization model is constructed by fusing the three-phase imbalance treatment target of the power distribution network and the carbon emission reduction target of the power distribution network; and solving an optimization problem by combining a heuristic optimization algorithm with power flow simulation software of the power distribution network so as to reduce network loss and carbon emission of the power distribution network. According to the method, demand response resources are fully utilized, carbon emission reduction of the power distribution network and reduction of the three-phase unbalance degree of the power distribution network are achieved, landing of the dual-carbon policy in the power distribution network is promoted, and the method has important value.

Description
