Abstract
Description
Technical Field
[0001] This document relates to the technical field of electric-hydrogen synergistic system planning, and in particular to a method and device for planning an electric-hydrogen synergistic system taking into account the benefits of the ancillary service market. Background Art
[0002] At present, hydrogen energy, especially green hydrogen industry, is developing rapidly. Green hydrogen is hydrogen produced by green electricity. Therefore, the coupling relationship between hydrogen and electricity will become closer. In particular, in the process of preparing green hydrogen, the electric hydrogen production device allows the use of flexible and fluctuating operation mode to track the fluctuation of new energy, and can participate in the peak load regulation, standby and other auxiliary services of the power system. By converting the flexible adjustment value into economic value in the auxiliary service market, it can be used as the income of the electric-hydrogen synergistic system. At present, the coordinated development of electric and hydrogen is mostly at the conceptual level. The invention patent CN116579115B discloses a system planning method and device for the coordinated interaction of electricity and hydrogen to solve the problem of the lack of electric-hydrogen coordinated planning method.
[0003] However, current methods for planning electric-hydrogen synergy are mostly considered from the perspective of the overall cost of the electric-hydrogen system, that is, the optimization model for planning is to pursue the lowest overall system cost of electricity and hydrogen coupling synergy, and fails to consider the participation of electric-hydrogen synergy elements in auxiliary services such as peak regulation and standby of the power system. The former pursues the overall optimality of the electric-hydrogen coupling system and is more idealistic, which is suitable for national or regional macro-level planning; but the latter is more in line with the specific operating logic of actually stimulating electric-hydrogen synergy, and is closer to the actual strategic selection of the electric-hydrogen synergy system, and is suitable for carrying out capacity planning and configuration of various elements at the specific system project level.
[0004] Therefore, this application proposes a method and device for planning an electric-hydrogen synergistic system that takes into account the benefits of the ancillary service market, so as to solve the problem of the lack of a current electric-hydrogen synergistic system planning method that takes into account the benefits of participating in the ancillary service market and is oriented towards stimulating the flexible adjustment value of the electric-hydrogen synergistic system.
