Embodiment Construction

[0055] This model considers the year as the decision-making time unit, and the decision variables in the model mainly include the following three categories: the first category is Indicates the expansion capacity of the u-type power supply that supplies power to the loads in area b in area a in year y, and a and b in the subscripts both represent areas. When a and b represent the same area, such as When , it indicates that the new capacity of this type of unit is used to balance the local load in area a, which is the local capacity. When a and b represent different areas, it indicates that the newly added capacity of this type of unit is used to balance the load in area b, which is the outgoing capacity. The second category is Indicates the newly added capacity of the power transmission channel between area a and area b in the yth year. The third category is is the output of the u-th power supply in area a that supplies power to the loads in area b under time period t ...

Abstract

The invention discloses a low-carbon power supply grid planning model considering carbon emission flow. A target function is shown in specification as follows, wherein Cy, C<O>y, C<G>y and C<T>y respectively express total investment construction cost, fixed running cost, variable running cost and regional connection line onstruction cost of a system in the y(th) year, the fifth item in the target function expresses carbon transaction cost, the Cy, the C<O>y and the C<T>y are described by investment problem, the C<G>y is described by running sub-problem, Y expresses all years to be planned, and r expresses inflation rate.

Description

technical field [0001] The invention relates to the field of grid planning and operation, in particular to a low-carbon power grid planning model considering carbon emission flow. Background technique [0002] Power system planning includes two levels of power supply planning and grid planning, and is an important preliminary work for the development of power systems. The fundamental purpose of power planning is to find the most economical The power development plan can meet the requirements of operational reliability. my country has put forward the low-carbon development goal of "decreasing the carbon emission intensity per unit of GDP by 40%-45% in 2020 compared with 2005". The realization of this goal depends on the low-carbonization of my country’s energy structure on the one hand, and on the optimization of industrial structure and energy use methods on the other hand. Different regions have different industrial structures and energy endowments, and their contribution ...
