Problems solved by technology

[0003] Accompanying the large-scale grid-connection of clean energy comes a series of clean energy consumption problems: on the one hand, because large-scale clean energy is mostly far away from the load center, limited by the load level of the regional power grid and the power structure, the dispatching and operation of clean energy The situation of abandonment of wind and water is serious; on the other hand, the construction of main power plants in the end system does not match the growth rate of electricity demand, resulting in large-scale power cuts in many provinces and cities. Transmission of large amounts of electrical energy, for which the input-side system is increasingly dependent on external power

Embodiment Construction

[0076] Hereinafter, the technical solutions provided by the present invention will be introduced in detail and clearly with reference to the accompanying drawings.

[0077] The invention relates to an optimization method for cross-regional tie-line transaction based on SCUC for promoting clean energy consumption. The method can provide an optimal cross-regional tie-line transaction power, which uniformly considers the load difference and peak load of clean energy sending and receiving ends. Based on the complementarity of valley difference and time difference, the tie-line power transaction plan and unit combination plan that promotes the maximum consumption of clean energy are selected.

[0078] Based on the input and output area interconnection system, fully consider the physical and economic operation constraints of power grid operation, and consider the constraints of the minimum operation mode of thermal power units, the constraints of the tie line power transaction scheme...

Abstract

The invention provides a trans-regional connecting line transaction optimization method based on SCUC (Security Constrained Unit Commitment). The method comprises steps of setting parameters of power grids, units and trans-regional connecting lines of input and output areas; selecting a trans-regional power transaction planning method; and establishing an input-output unite security constrained unit commitment model and optimizing model calculation. The technical scheme provided by the invention improves the pertinence of power transaction planning of different regions and different power types, can estimate whether the capacity of the trans-regional connecting line meets expansion requirements or not, and provides the technical support for connecting line capacity expansion.

Description

technical field [0001] The invention relates to an optimization method in the field of electric power market and electric power automation, in particular to an optimization method for cross-region tie-line transactions based on SCUC. Background technique [0002] The Chinese government attaches great importance to the development and utilization of clean energy, and even promotes clean energy power generation and the optimal allocation of large-scale clean energy to a national strategic level. With the introduction of a series of new energy development policies in my country, large-scale clean energy development and utilization has become a major measure to improve the energy structure, build a low-carbon society, and maintain sustainable economic and social development. [0003] With the large-scale grid connection of clean energy comes a series of problems in the consumption of clean energy: on the one hand, because large-scale clean energy is far away from the load center...
