Problems solved by technology

However, multiple objectives are optimized at the same time. Due to the different interrelationships among the objectives, if some objectives conflict with each other, some objectives complement each other, making the multi-objective optimization of the wind power hydrogen production energy storage system more complicated than the single-objective optimization.

Abstract

The invention discloses a multi-objective optimization method for an offshore wind power hydrogen production and energy storage system, and belongs to the field of new energy. The method specifically comprises the following steps: determining that the offshore wind power hydrogen production and energy storage system takes reliability, economy and wind curtailment quantity as optimization targets, constructing a fitness function of multiple optimization targets, compiling a program code for solving the fitness function based on a multi-target particle swarm optimization algorithm in application software, running a program, and completing the optimization of the wind curtailment quantity. And obtaining a Pareto frontier curved surface of the multi-objective optimization problem, and determining an optimal solution of the capacity ratio according to the Pareto frontier curved surface graph and the preference for each objective. According to the multi-target capacity optimization method for the offshore wind power hydrogen production and energy storage system, a decision maker can determine the optimal capacity ratio of the system according to economy, reliability and wind curtailment preference.

Description

technical field [0001] The invention relates to the related technical field of offshore wind power generation accommodation, in particular to a multi-objective optimization method for an offshore wind power hydrogen production and energy storage system. Background technique [0002] Offshore wind resources are abundant and widely distributed, which is an important field for the development and utilization of renewable energy. However, offshore wind energy has strong intermittency, randomness, and volatility, which brings many problems to the safe grid connection and reliable consumption of offshore wind power. Hydrogen production from wind power can be used as an effective means to absorb abandoned wind and improve the utilization of wind resources. It is a hot spot in the development and research of offshore wind power. [0003] The multi-objective optimization of offshore wind power hydrogen production energy storage system can improve system reliability, economy and redu...
