Problems solved by technology

However, the two objective functions are not in a linear relationship. When the power generation output changes, their change rates are different, making it difficult for WSM to take into account the difference in magnitude and improvement potential of the two.

Abstract

The invention discloses an electric power system economic emission scheduling method based on collaborative normalization, which comprises the following steps of A, generating M candidate solutions, and calculating the fuel oil cost, the waste gas emission amount and the constraint violation amount of the candidate solutions; B, carrying out collaborative normalization processing on the candidatesolutions; C, selecting the candidate solution with the minimum penalty function value as the optimal solution; D, if the constraint violation quantity of the optimal solution is 0, determining that the optimal solution is the optimal power system economic emission scheduling scheme meeting all constraint conditions, and otherwise, repeating the steps A to C. According to the method, the physicalquantity line, the magnitude order and the improvement potential difference between the fuel oil cost and the waste gas emission are eliminated through a collaborative normalization method, the problem that cost saving and pollution reduction are difficult to achieve at the same time in the power generation process is effectively solved, the electric energy utilization rate is increased, and the power supply and demand balance is guaranteed.

Description

technical field [0001] The invention relates to a method for dispatching economic discharge of a power system, in particular to a method for dispatching an economic discharge of a power system based on collaborative normalization. Background technique [0002] At present, the power system still mainly uses thermal power generation, its technology is mature and its operation is stable. However, a large amount of fossil fuels need to be burned in the process of power generation. On the one hand, power plants need to pay high production costs. On the other hand, the waste gas generated is likely to cause environmental pollution, which is not conducive to green and sustainable development; taking into account the reduction of waste gas emissions and Saving fuel costs has always been an important research content of power system economic dispatch. [0003] Power system economic emission dispatch is a grid dispatching technology based on thermal power generation: this technology ...
