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 present invention introduces load optimization management by means of time period shifting, peak cutting and other means. First, a mathematical model is established, and then the constraints corresponding to the two optimization methods of peak shifting and peak cutting are given, and the linear programming of these user loads participating in the optimization is performed to obtain the final function after power demand side management. Specific steps such as figure 1 Shown:

[0063] Step S1, identify the load pattern of the new user according to the loading parameters of the new user, call the decision tree to classify it through the load characteristic index provided by the new loading user, and obtain the approximate load curve of the new loading user;

Abstract

The invention discloses a load optimization method based on a load demand coefficient and time-segment peak shifting and peak clipping, and the method comprises the steps: S1, considering the time sequence of a power load of a user, and calculating the load demand coefficient of an existing user in a transformer area; S2, performing load mode identification on the new users according to the installation parameters of the new users, and calling a decision-making tree to classify the new users through load characteristic indexes provided by the new installation users to obtain an approximate load curve of the new installation users; S3, after a large number of new users are accessed, calculating a load demand coefficient of the transformer area users; S4, carrying out load optimization management through time period peak shifting; and S5, on the basis of time period peak shifting, performing peak clipping operation on a user by means of an energy storage system, and the load optimizationmanagement target being that the demand 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 a time period peak shift and peak clipping, and belongs to the technical field of power system demand response. Background technique [0002] In the early 1990s, electricity demand side management was introduced into my country from the United States and Europe. The development of power demand side management is roughly divided into three stages: 1993-2003 to carry out the introduction and pilot of power demand side management; One million kilowatts, and more than 70% of the country's power supply shortages have been resolved through measures to improve power consumption. [0003] At present, in my country's power demand side management technology, the orderly use of electricity has become an important and effective measure to reduce the load during peak hours of electricity consumption and alleviate the tension of power supply during peak hours. In addition, m...
