Power dispatching method and device based on peak clipping potential

Abstract

The invention discloses a power dispatching method and device based on peak clipping potential, and the method comprises the steps: constructing a dimension reduction index through historical electrical load monitoring data, so as to achieve the dimension reduction of the data, and then removing an abnormal daily load curve through a weighted clustering method, so as to achieve the prediction of the daily load curve. Obtaining a typical daily load curve based on the daily load curves corresponding to the dimension reduction index values in the remaining classes, then carrying out time period division on the typical daily load curve through a load decomposition mode, namely according to starting and stopping of different electrical loads in the users, and decomposing the electrical load of each time period to obtain a daily load curve; according to the method, daily load curves corresponding to all electrical loads in each time period are formed to obtain specific load operation data in the user, and finally, the actual load reduction rate of the user is obtained through reconstruction of the load reduction rate of the load in the user, so that the accuracy of peak clipping potential evaluation is improved. Therefore, superior power grid dispatching personnel can be assisted to supply reliable power meeting the requirements of production and operation to users, and safe and economical operation of a power system is ensured.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a power dispatching method and device based on peak-shaving potential. Background technique [0002] At present, with the increase of electricity consumption year by year, the peak-to-valley load difference of the power system is also gradually widening, which seriously affects the smooth operation of the power system. It is necessary to reduce the peak-to-valley load difference of the power grid to balance the power generation and power consumption. Among them, peak shaving refers to a measure to adjust the electricity load. The specific location is based on the electricity consumption rules of different users, and the electricity consumption time of various users is arranged and organized in a reasonable and planned way; The peak load power value that can be curtailed in case of operational production. [0003] In the existing evaluation methods for peak-shaving pot...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the evaluation method of the peak-shaving potential in the prior art, the extraction of the typical daily load curve is too rough and the empirical load reduction rate is used for each user, resulting in accurate evaluation of the peak-shaving potential Low, affecting the rationality of subsequent power dispatch
