Embodiment Construction

[0061]In order to deepen the recognition and understanding of the present invention, the scheme is further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0062] The invention introduces load optimization management by means of time shift peak, peak shaving and the like. First, a mathematical model is established, and then the constraints corresponding to the two optimization methods of time shift and peak shaving are given, and the user loads participating in the optimization are linearly programmed to obtain the final function after power demand side management. The specific steps are as figure 1 shown:

[0063] In step S1, load pattern recognition is performed on the new user according to the loading parameters of the new user, and a decision tree is invoked to classify it through the load characteristic index provided by the new user, and the approximate load curve of the new user is obtained;

[0064] Step S2, after a large num...

Abstract

The invention discloses a load optimization method based on the load demand coefficient and time-period peak staggering and peak shaving, including: S1, considering the timing of the user's power load, calculating the load demand coefficient of the existing users in the station area; S2, according to Identify the load pattern of the new user's loading parameters, call the decision tree to classify them through the load characteristic index provided by the new loading user, and obtain the approximate load curve of the new loading user; S3, after a large number of new users access , to calculate the load demand coefficient of users in the station area; S4, to perform load optimization management through peak shifting during time periods; S5, to perform peak shaving operations on users with the help of energy storage systems on the basis of peak shifting during time periods, and the load optimization management goal is to demand The quantity coefficient is equal to 0.95.

Description

technical field [0001] The invention relates to a load optimization method based on a load demand coefficient and time period shifting and peak shaving, and belongs to the technical field of electric power system demand response. Background technique [0002] In the early 1990s, DSM was introduced into my country from the United States and Europe. The development of power demand side management is roughly divided into three stages: the introduction and pilot of power demand side management from 1993 to 2003; the preliminary application from 2004 to 2009; the initial implementation stage from 2010 to the present, with a total of about 1,600 peak loads transferred. million kilowatts, more than 70% of the country's power shortage has been solved through measures to improve electricity consumption. [0003] At present, orderly electricity consumption in my country's power demand side management technology has become an important and effective measure to reduce the load during t...
