Problems solved by technology

[0005] However, due to the close coupling of electricity and peak shaving services, it is difficult to take into account the impact of the two clearing results using the above two-stage clearing model, so that the clearing results are often not the global optimal solution, resulting in waste of resources

Embodiment Construction

[0055] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0056] The traditional power generation method is generally coal-fired unit power generation. With the rise of clean energy, wind farm power generation has become another important way of power supply. However, due to the characteristics of wind power generation that are greatly affected by environmental factors, the power generation is not stable. , it is necessary to rely on coal-fired units to provide peak-shaving auxiliary services to stabilize the power sup...

Abstract

The invention relates to an electric quantity clearing method and equipment. The electric quantity price and the wind curtailment price of each wind power plant, the electric quantity price and the peak regulation price of each coal-fired unit are low and power demand prediction and other data are obtained and inputted into a pre-constructed electric quantity clearing model to calculate and outputa power generation plan and a peak load regulation capacity plan of each coal-fired unit and a power generation plan of each wind power plant, and then the power generation of each coal-fired unit and each wind power plant is controlled according to the output power generation plan and peak load regulation capacity plan of each coal-fired unit and the output power generation plan of each wind power plant. The relationship between power generation and peak regulation service is comprehensively considered so that simultaneous clearing of the power generation and peak regulation services can berealized and the operation of the generator set meets the safety specification.

Description

technical field [0001] The invention relates to the technical field of power system dispatching operation, and in particular to a method and equipment for clearing electric quantity. Background technique [0002] my country's medium and long-term electricity market trading system is becoming more and more perfect. At present, electricity spot trading and peak-shaving service trading have become the two most important trading varieties. The clearing method in the market trading mechanism is mainly two-stage clearing of electricity spot trading and peak shaving service trading. The transaction content and key points of each stage are as follows: [0003] The first stage is the spot trading of electricity without considering peak-shaving services. At this stage, coal-fired units only provide basic peak-shaving services, and do not provide paid peak-shaving services. Wind farms share the demand for peak-shaving services in a certain proportion; [0004] The second stage is the ...
