Problems solved by technology

[0004] On the other hand, due to the user's production shift, equipment start-stop time, etc., the user's daily load curve is always fluctuating, and the loads of different users may have complementarity in time sequence, which may make different users The maximum load after superposition of the load curves is much smaller than the result of the direct addition of the maximum loads of these users

Embodiment Construction

[0074] The present invention will be further explained below in conjunction with the accompanying drawings. Such as figure 1 As shown, an optimal power purchase method for load retailers in the electricity market environment includes the following steps:

[0075] Step 1) The retailer collects the daily 96-point historical load data of the users under its jurisdiction;

[0076] Step 2) data preprocessing, eliminating abnormal data; the preprocessing steps are specifically:

[0077] 2.1) It is believed that three consecutive data within a short period of time, that is, within 15 minutes, are relatively stable and there is no sudden change. Combined with statistical principles, use sample statistical indicators and set thresholds to judge whether there is abnormal data:

[0078] Average five consecutive data near a certain load point to form a smoothed load sequence:

[0079] x i , n , ...

Abstract

The invention discloses an optimal electricity purchasing method for a load retail dealer under electricity market environment. The optimal electricity purchasing method for the load retail dealer under the electricity market environment comprises the following steps of enabling a retail dealer to collect history load data at nine and six every day of governed users; selecting load data based on time dimension in one year of the users to be performed on clustering analysis and classifying the load into typical types; extracting a monthly typical load curve according to a clustering analysis result; establishing a load optimization clustering model in consideration of complementarity in the time sequence of load characteristics of different users and enabling a retail dealer economic benefit to be best by optimizing the electricity purchasing scheme. The optimal electricity purchasing method for the load retail dealer under the electricity market environment optimizes and models the electricity purchasing behavior of the retail dealer in the electricity market, provides scientific theory support for operation of the electricity market and fully plays the operation efficiency.

Description

technical field [0001] The invention relates to the field of power system control, in particular to an optimal power purchase method for load retailers in the power market environment. Background technique [0002] In order to allocate resources more rationally, improve resource utilization, and promote the coordinated development of the power industry and society, economy, and environment, the power industry in many countries is currently breaking monopoly, deregulating, introducing competition, and establishing a power system in the power market. reform. In my country, with the rapid development of the power industry, the reform of the power system has gradually deepened. In the field of power generation, a competition mechanism has been gradually introduced, that is, a market mechanism in which power generation companies compete to connect to the grid according to electricity prices, and a preliminary power marketization has been formed. [0003] With the advancement of ...
