Embodiment

[0040] figure 1 It is a schematic diagram of a hydrogen storage system in the electricity / hydrogen market.

[0041] In this example, if figure 1 As shown, a hydrogen storage system under the electricity / hydrogen market mainly includes: wind farm, electrolyzer, hydrogen storage tank, electricity market and hydrogen market; all the energy of the system comes from the wind farm;

[0042] like figure 2 Shown, the present invention a kind of operation optimization method of hydrogen storage system under electricity / hydrogen market, comprises the following steps:

[0043] S1. Construct a wind-electrolysis hydrogen storage system model;

[0044] S1.1. Construct the output model of the fan module in the wind-electrolysis hydrogen storage system;

[0045]

[0046] in, is the output power of wind power in scenario s at time t, p e is the rated power of the fan, is the real-time wind speed in scene s at time t, V e ,V ci and V co Respectively represent rated wind speed, c...

Abstract

The invention discloses an operation optimization method for a hydrogen storage system in an electric power / hydrogen market. The operation optimization method comprises the steps of: firstly constructing a model of a wind-electrolysis hydrogen storage system; secondly,measuring the risk of the wind-electrolysis hydrogen storage system in an electric power market / hydrogen market environment throughconsidering CVaR; thirdly, constructing an objective function and constraint conditions of the hydrogen storage system based on the risk value; and optimizing the objective function of the hydrogen storage system by using a scene-based random optimization algorithm, thereby acquiring a maximum profit max REH.

Description

technical field [0001] The invention belongs to the technical field of mixed renewable energy, and more specifically, relates to an operation optimization method of a hydrogen storage system under the electricity / hydrogen market. Background technique [0002] With the reduction of the cost of renewable energy and the increase of social demand, the installed capacity of wind power in my country will increase rapidly in the future. my country is rich in wind energy resources, including offshore wind power and onshore wind power. With the increase of wind power penetration, traditional fossil fuels are gradually being replaced, and some traditional power plants are on standby all year round, only providing necessary system auxiliary services for grid stability. However, with the rapid development of wind power, the problem of wind power accommodation has become more and more serious. Compared with traditional power sources, wind power has volatility and uncertainty. As a new...
