Interest margin calculating method and device

Abstract

The embodiment of the invention provides an interset margin calculating method and device, and belongs to the field of electricity. The method comprises the steps of obtaining the actual generating capacity of a power plant and the needed generating capacity of a dispatching instruction; on the basis of the actual generating capacity and first preset rules, obtaining first benefit data; on the basis of the needed generating capacity and second preset rules, obtaining second benefit data; adopting the first benefit data and the second benefit data for margin calculation, and obtaining first interest margin data. According to the method and device, electricity generating output which is not performed on the basis of the dispatching instruction for an owned power plant is punished, then, theinterest margin is lowered, and the owned power plant can perform dispatching according to the dispatching instruction.

Description

technical field [0001] The present invention relates to the field of electric power, in particular, to a method and device for calculating a spread. Background technique [0002] With the large-scale and rapid development of new energy in western China, problems such as insufficient power grid consumption and transmission capacity, and lack of peak-shaving capacity have become increasingly prominent, resulting in serious abandonment of wind and light. At this stage, the potential and effect of requiring power generation companies to provide in-depth peak-shaving and other auxiliary services through planning means and dispatch instructions are increasingly limited, and it is urgent to establish a new market-oriented power auxiliary service mechanism. In June 2016, the National Energy Administration approved the "Regulations for the Implementation of Peak Shaving Alternative Transactions between New Energy Power Generation Enterprises and Coal-fired Power Plants in Xinjiang Re...

Problems solved by technology

[0003] In the existing technology, the power plant generates power according to the most profitable power generation method, instead of considering the actual dispatching instructions, so that the actual power plant substitution transaction cannot be operated optimally

[0004] When the power generation capacity of new energy is at a high level, self-provided power plants are required to reduce the output of generators, but in order to maximize profits, self-provided power plants are unwilling to reduce the output of generators, resulting in increased curtailment of wind and light from new energy sources; When new energy sources are limited, it is necessary for the units of self-provided power plants to increase output and reduce the power off-grid from the grid. When self-provided power plants believe that increasing output will lead to a decrease in profits, they are unwilling to increase output according to instructions, resulting in off-grid power from conventional Obtaining electricity from the additional generation of energy generators cannot achieve the purpose of replacing transactions
