摘要:

随着海上风电深度开发及油气平台低碳化推进,海上独立能源岛将成为海上风电深度消纳新模式。针对海上风电不确定性导致海上独立能源岛内电解槽频繁启停、运行不均衡,以及电-氢-水-气多元耦合经济、灵活运行配置复杂难题,提出一种考虑多电解槽协同的海上独立能源岛不确定性双层优化配置方法。首先,提出基于K-means算法和蒙特卡洛综合模拟复杂海上风电不确定性的场景生成方法;其次,构建外层以效益最大、内层考虑多电解槽协同的多目标均衡优化控制的系统双层优化配置模型,并通过改进粒子群-Gurobi联合算法对模型进行求解;最后,通过算例对比考虑多电解槽协同与不考虑多电解槽协同以及确定性模型和不确定性模型,验证所提方法的有效性和优越性。

Abstract:

With the in-depth development of offshore wind power and the low-carbon advancement of oil drilling platforms, offshore independent energy islands will become a new model for the in-depth consumption of offshore wind power. To address the challenges of frequent start-stop and uneven operation of electrolyzers in offshore independent energy islands due to the uncertainty of offshore wind power, and the complex problem in economic and flexible operation configuration of the multi-coupling of electricity-hydrogen-water-gas, this paper proposes a bi-level optimization configuration method for offshore independent energy islands that considers the coordination of multiple electrolyzers under uncertainty. Firstly, a method for generating complex offshore wind power uncertainty scenarios is proposed based on the K-means algorithm and Monte Carlo simulation. Secondly, a bi-level optimization configuration model is constructed, with the outer layer aiming to maximize benefits and the inner layer considering the coordination of multiple electrolyzers for multi-objective equilibrium optimization control, and the model is solved using an improved particle swarm-Gurobi hybrid approach. Finally, the methods with and without the coordination of multiple electrolyzers, as well as the deterministic and uncertain models are compared through case studies, which verifies the effectiveness and superiority of the proposed method in this paper.
