The invention discloses a hydrogen storage configuration and control collaborative optimization method for improving economic benefits of a wind power plant, and belongs to the field of new energy. The method specifically comprises the following steps: acquiring a maximum active power generation power curve of each fan within a period of time, and establishing a steady-state mathematical model of each component such as a hydrogen production electrolytic cell, a storage battery, a hydrogen compressor and a hydrogen storage tank in the wind / hydrogen / storage coupling system; and determining an economical efficiency optimization target of the wind / hydrogen / storage coupled grid-connected system and forming an economical efficiency configuration optimization problem, carrying out convex processing on the optimization problem to enable the optimization problem to meet convex optimization conditions, and solving the optimization problem by adopting convex optimization to synchronously obtain the optimal capacity configuration of each component under optimal control. According to the method, system configuration and control can be synchronously optimized, the nonlinear efficiency of the storage battery and the electrolytic cell is considered in optimization, the design period of the wind / hydrogen / storage coupled grid-connected system is greatly shortened, and the design and control precision is improved.
Description
technical field [0001] The invention relates to the related technical fields of wind power consumption and renewable energy hydrogen production, in particular to a hydrogen storage allocation and control collaborative optimization method for improving the economic benefits of wind farms. Background technique [0002] Wind power generation is one of the important technologies for the utilization of renewable energy. my country's land and sea wind resources are abundant, which can provide huge power support for national production and residents' lives. Affected by the intermittency, volatility and uncontrollability of wind resources, wind farms, especially offshore wind farms, have to abandon a large amount of peak wind power to limit the grid-connected active power, so as to ensure the stable and safe operation of the large power grid. A large amount of abandoned wind energy prevents efficient development and utilization of wind farms, resulting in limited production capacity...
