Embodiment Construction

[0031] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0032] The present invention provides a low-carbon available transmission capacity calculation method including wind farms, such as figure 1 As shown, firstly, the maximum available transmission capacity and the minimum carbon emissions under CCS installations are used as the objective functions to obtain the single-objective optimization results; the objective function is normalized, and the utopia line is established in the normalized space; the uniformity on the utopia line Points are taken, and the normal boundary intersection (NBI) method is used to convert the multi-objective optimization into a single-objective optimization problem. Aiming at the chance constraints, a posterior adjustment algorithm combining the semi-invariant method and the Cornish Fisher series is used , transforming the chance constraint into a deterministic form; continu...

Abstract

The invention discloses a low-carbon usable transmission capacity calculation method adopting a wind power plant. Through multi-objective programming and coordinative optimization, usable transmission capacity and carbon emission are determined. The method includes the steps that firstly, a multi-objective optimization model containing the wind power plant and a carbon capture device is established, the largest transmission capacity and the smallest carbon dioxide emission serve as objective functions, and a solution of the determinacy multi-objective optimization model is acquired through a normal boundary bracketing method; according to the indeterminacy of wind power output, a system safety constraint is expressed in a chance constraint mode; based on the acquired determinacy solution, probabilistic power flow calculation is conducted, a chance constraint is adjusted to be a determinacy constraint through a semi-invariant and a Cornish Fisher level, and solutions are acquired continuously and iteratively till the condition of the chance constraint is met. By the adoption of the method, the relationship between safety and environment friendliness of a power system is coordinated and the method has the practical significance under the low-carbon emission-reduction background.

Description

technical field [0001] The invention relates to a low-carbon available transmission capacity calculation method including a wind farm, belonging to the field of power system optimization operation. Background technique [0002] In recent years, with the continuous growth of my country's economic aggregate, the consumption of traditional fossil energy has been increasing, and the problems of environment and climate change have become increasingly prominent. Reducing carbon dioxide emissions is an urgent problem that is crucial to controlling the greenhouse effect and slowing down global warming. In order to promote "green development, low-carbon development", there are currently two main types of low-carbon emission reduction countermeasures in the power industry: one is to increase the proportion of clean energy. As an efficient and clean energy, wind energy has been widely used worldwide. ; The second is to use carbon capture and storage (carbon capture and storage, CCS) t...
