CCS transformation path optimization method and system, storage medium and computing equipment

Abstract

The invention discloses a CCS transformation path optimization method and system, a storage medium and computing equipment. According to the method, the number of times of CCS transformation of the target coal-fired power plant, the newly increased annual trapping and storage capacity after the first CCS transformation of the target coal-fired power plant and the accumulated newly increased annual trapping and storage capacity after the last CCS transformation of the target coal-fired power plant are adopted; according to the method, decision variables such as the moment of the first CCS transformation of a target coal-fired power plant and the time interval between two adjacent CCS transformation describe CCS transformation paths, the moment of each CCS transformation and the newly-added annual trapping and storage capacity are calculated according to the decision variables, the accumulated total profit corresponding to each CCS transformation path is calculated, and therefore the optimal CCS transformation path is obtained. According to the method, optimization of the CCS transformation path is achieved, and due to the fact that only a small number of decision variables exist, the huge calculation amount of traversing all possible CCS transformation paths of the target coal-fired power plant is avoided, and the optimization effect and the calculation speed are both considered.

Description

technical field [0001] The invention relates to a CCS transformation path optimization method, system, storage medium and computing equipment, and belongs to the field of carbon neutrality and low-carbon transformation of energy and power. Background technique [0002] Carbon capture and storage technology (Carbon Capture and Storage, CCS) is recognized as the main technical option to achieve low-carbon development. It is an emerging technology that is expected to realize large-scale low-carbon utilization of fossil energy, and has attracted great attention from the international community. Coal-fired power plants transformed by CCS can provide low-carbon electricity with flexible adjustment capabilities, which will help ensure the reliability of new power systems dominated by new energy in the future. [0003] The investment cost of CCS technology is high, and the technology maturity is still in progress. The CCS retrofit for a single target coal-fired power plant usually n...

Problems solved by technology

[0003] The investment cost of CCS technology is high, and the technology maturity is still in progress. The CCS retrofit for a single target coal-fired power plant usually needs to be carried out in stages. The current CCS retrofit evaluation research for coal-fired power plants is usually analyzed based on a single retrofit. Path optimization problem that fails to consider transformation
