A power dispatching prediction method based on three-public dispatching and economic dispatching

Abstract

The invention discloses a power dispatching prediction method based on three-public dispatching and economic dispatching. The power dispatching prediction method includes: Dividing the total requiredelectric quantity into planned partial generating capacity and market partial generating capacity, and respectively determining planned partial predicted generating capacity and predicted installed capacity of each power supply by utilizing the state information and the planned partial generating capacity of each power supply so as to determine the market partial predicted installed capacity; Anddetermining the range of the market part prediction hour power generation amount of each power supply according to the constraint condition, determining the lowest power consumption cost by using themarket part prediction hour power generation amount and the prediction hour market electricity price of each power supply within the range, and taking the prediction power generation amount and the installed capacity of each power supply as power dispatching prediction results. In a changeable marketization power transaction environment, the future power dispatching scheme can be reasonably predicted and planned, so that the technical purposes of optimizing the power supply structure, realizing low-carbon transformation of a power system, promoting development of clean energy and the like areachieved.

Description

technical field [0001] The present invention relates to the technical field of electric power dispatching, and more specifically, the present invention is a power dispatching prediction method based on three public dispatching and economic dispatching. Background technique [0002] With the large-scale development of clean energy, the proportion of electric energy in the final energy consumption continues to increase, and the role of the power system in the energy system is becoming more and more critical; Slow but still maintain a certain level of growth. Under the conventional transformation scenario, it is estimated that China's total electricity demand will reach 10,500TWh by 2035; however, with the transformation of electricity demand patterns and the rise of environmental protection costs, such as the development of sustainable clean In line with carbon emission reduction requirements, the power industry is facing a huge transformation challenge. Looking at historical ...

Problems solved by technology

[0005] In order to solve the problems that the existing technology cannot adapt to the changes in the power supply structure and the real-time power dispatching mode caused by the change of the market-oriented power trading ratio under the reform process of the future power market, the present invention provides an innovative power dispatching based on three public dispatching and economic dispatching The prediction method uses the three-public dispatching model to allocate part of the planned electricity, and distributes the market part of the electricity through the economic dispatching model. Based on the principle of the lowest electricity cost, the power generation of various power units in the future can be obtained, so as to achieve a reasonable allocation of electricity. Scheduling, optimizing power structure, reducing carbon emissions and other technical purposes
