A low-carbon power grid optimization planning method

Abstract

The invention relates to a low-carbon power source and power grid optimization planning method. The method includes the steps that various power source capacities in each area are divided into the local capacities and the delivery capacities, and inter-area point-to-point direct-sending lines are built in an equivalent network so that inter-area electric quantity flowing and inter-area carbon emission transferring can be defined, and electricity use carbon emission can be conveniently measured; decision variables of a low-carbon power source and power grid optimization model are built, the low-carbon power source and power grid optimization model composed of an objective function and constraint conditions is built with the decision variables, and the constraint conditions in the low-carbon power source and power grid optimization model are converted to be in the mode that the constraint conditions can be calculated through matrixes; the low-carbon power source and power grid optimization model is solved by compiling a solving program, and low-carbon power source and power grid optimization planning of various power sources and power transmission lines in an electric system is obtained, so that the electric system has the optimal economic benefits in the low-carbon development mode. By means of the low-carbon power source and power grid optimization planning method, the technical support is provided for improving the low-carbon level of electric system planning.

Description

technical field [0001] The invention belongs to the technical field of power system optimization analysis, in particular to a power grid optimization planning method. Background technique [0002] As energy issues and climate change issues become increasingly prominent, achieving low-carbon development and reducing excessive consumption of fossil energy has gradually become a common goal of human society. The core of low-carbon development is technological innovation, institutional innovation, and changes in the concept of development, which will involve the readjustment of production models, lifestyles, and values, and are closely related to national rights and interests. [0003] As my country's basic energy sector, the power industry is also the industry with the largest carbon dioxide emissions. By 2011, the carbon emissions of the whole society in my country will exceed 8 billion tons, and the per capita CO 2 Emissions have also exceeded the global average level. At t...
