Capacity configuration method and system for flexible electro-hydrogen production, storage and injection integrated station

Abstract

The invention discloses a capacity configuration method and system for a flexible electricity-hydrogen production, storage and injection integrated station. The method comprises the steps that relevant information of capacity configuration of the flexible electricity-hydrogen production, storage and injection integrated station is obtained; on the basis of the acquired related information, clustering by using a K-means algorithm to generate a typical operation scene set S required by the capacity configuration of the flexible electricity-hydrogen production, storage and injection integrated station; on the basis of the typical operation scene set S, under a capacity configuration-operation verification integrated framework, a capacity configuration model of the flexible electricity-hydrogen production, storage and injection integrated station is constructed by taking the minimum level annual total cost as a target; and solving the capacity configuration model of the flexible electricity-hydrogen production, storage and injection integrated station to obtain an optimal capacity configuration scheme of a wind power generation system, a photovoltaic power generation system, an electric energy storage system, an electrolytic bath, a hydrogen storage tank and a hydrogen adding machine, thereby realizing the capacity configuration of the flexible electricity-hydrogen production, storage and injection integrated station. According to the method, the economy and flexibility of capacity configuration of the in-station equipment can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy, and in particular relates to a capacity configuration method and system of a flexible electric hydrogen production, storage and injection integrated station.
