Document Type and Number:
WIPO Patent Application WO/2024/046098
Kind Code:
A1
Abstract:
Disclosed in the present invention is a planning assistance method for an electricity-gas coupled integrated energy system, comprising the following steps: constructing an objective function of a transformation model on the basis of an electricity-gas coupled integrated energy system condition; constructing a constraint condition; solving the objective function under the constraint condition; and implementing a planning scheme by using a solving result, wherein the constraint of the objective function comprises a gas network model constraint, a power grid model constraint, a carbon capture power plant transformation model constraint, and an electricity-to-gas (PtG) constant-address and constant-volume model constraint. According to the planning method provided by the present invention, a conventional thermal power plant is transformed into a carbon capture power plant, the carbon capture power plant is coupled to a natural gas system by means of PtG, the objective function of the transformation model is constructed on the basis of the electricity-gas coupled integrated energy system condition, and the objective function is solved by means of the gas network model constraint, the power grid model constraint, the carbon capture power plant transformation model constraint and the PtG constant-address and constant-volume model constraint, thereby achieving planning of the carbon capture power plant, reducing carbon emission, and increasing carbon income.
