Design method and system for electricity purchasing combination scheme of electricity retailing company

Abstract

The invention provides a design method and system for an electricity purchasing combination scheme of an electricity retailing company. Load and electricity price data of an electricity retailing company are collected; an electricity selling influence factor of the electricity retailing company is collected and simulated; an electricity purchasing combination optimization strategy model of the electricity retailing company is constructed and standardized processing is carried out; an electricity purchasing combination optimization strategy model after the standardized processing is obtained by using a parsing method, thereby obtaining an optimal decision vector; de-standardization processing is carried out on the optimal decision vector to obtain an actual decision vector, and profits of the electricity retailing company under the optimal decision are calculated; and according to the actual decision vector and the profits under the optimal decision, an electricity purchasing combination scheme of the electricity retailing company is generated. During the whole process, the load and electricity price data as well as the selling point influence factors of the electricity retailing company are taken into consideration comprehensively; and the n electricity purchasing combination optimization strategy model is built and the profits of the electricity retailing company are calculated; and thus the electricity purchasing combination scheme of the electricity retailing company is generated.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for designing a power purchase combination plan for a power retail company. Background technique [0002] With the development of science and technology, electricity has become an indispensable material for people's production and life, and people's demand for electricity is also increasing. The huge demand for electricity not only puts forward new requirements for the entire power supply unit (such as power stations, substations, and line maintenance inspections, etc.), but also has new problems for power sales units to overcome and solve. [0003] At present, the opening of the electricity sales market is an important part of the electricity market reform. Judging from the international practice of electricity market construction, the opening of the electricity sales market can help reduce electricity costs, optimize the energy structure, and improve th...
