Low-carbon dispatching method and device for electric power system based on large-scale wind power grid connection

Abstract

The invention relates to a low-carbon dispatching method and device for an electric power system based on large-scale wind power grid connection. The low-carbon dispatching method comprises the following steps of: (1) collecting power grid data of a given power grid system in the next dispatching cycle by a dispatching system of the electric power system; (2) capturing active load distribution values of a wind power farm and each generator by a low-carbon dispatching system according to the power grid data collected by the dispatching system of the electric power system; (3) making a new power generation executing plan by the dispatching system of the electric power system according to the active load distribution values of the wind power farm and the generators, which are captured by the low-carbon dispatching system; and (4) sending the new power generation executing plan, which is made by the dispatching center of the electric power system, to the wind power farm and a thermal power plant by a power generation executing system so as to execute the plan. The invention has the following advantages that the economy of power production is considered, and moreover, the protection of ecological environment is paid more attention to at the same time; and requirements for energy-saving and emission reduction are met, and low-carbon power production is promoted.

Description

technical field [0001] The invention relates to the field of power system dispatch and operation, in particular to a low-carbon dispatch method and device of a power system based on large-scale wind power grid-connected. Background technique [0002] By the end of 2010, the cumulative installed capacity of wind power in China reached 41,827MW, surpassing the United States for the first time to become the world's largest installed wind power country. As a "zero pollution, zero emission" green and clean energy, wind power is of great strategic significance for optimizing the energy structure, promoting energy conservation and emission reduction, and comprehensively promoting the development of my country's "low carbon economy". Under the background of the global energy shortage and the deteriorating ecological environment, the power industry, as a major energy consumption and pollutant discharger, under the premise of ensuring the safe and reliable supply of power, it is the g...

Problems solved by technology

[0004] The present invention mainly solves the traditional economic dispatch existing in the prior art with the goal of minimizing energy consumption, ignoring the damage to the ecological environment caused by electric power production, not reflecting "emission reduction", and not being able to evaluate different times well The "environmental benefits" between energy sources are not very suitable for technical issues such as power
