Method and system for medium-and-long-term power transaction curve decomposition

Abstract

The invention discloses a method and system for medium-and-long-term power transaction curve decomposition. The method comprises the following steps: S1, acquiring power consumer data, power medium and long term transaction contract data and a spot market predicted price curve; S2, according to the power consumer data, establishing a load prediction curve of the power seller in combination with the electric quantity in the power medium-and-long-term transaction contract data; S3, establishing a comprehensive price curve of medium-and-long-term power transaction according to the medium-and-long-term power transaction contract data; S4, establishing an electric power medium and long term transaction curve decomposition model according to the spot market prediction price curve, the load prediction curve of the electricity seller and the comprehensive price curve of the electric power medium and long term transaction; and S5, obtaining an optimized power seller load decomposition curve according to the power medium-and-long-term transaction curve decomposition model. The load decomposition curve of the electricity seller obtained by using the medium-and-long-term electric power transaction curve decomposition method can increase the income of an electricity selling company in the electric power transaction.

Description

technical field [0001] The invention relates to electricity trading and utilization, in particular to a method and system for decomposing electricity mid- and long-term trading curves. Background technique [0002] Since the issuance of the new round of electricity reform document No. 9, the electricity sales market has been in full swing with fierce competition. The upcoming spot market has put forward higher technical requirements for electricity sales companies. How to declare electricity can maximize the benefits of electricity sales companies and users? Curve decomposition has become one of the important tasks of electricity sales companies. In the existing technology, there is no efficient solution. [0003] At present, for the curve decomposition of medium and long-term power trading contracts, the following two methods are usually used: [0004] (1) Customize the decomposition curve, which is determined by the market players themselves. [0005] (2) Commonly used ...
