电-气联合储能的海上微能系统模糊随机规划

Fuzzy Stochastic Programming of Offshore MIES Including Electricity and Associated Gas Storage

海上油气工程是能源密集型系统,主要由供能系统与生产工艺系统2部分组成。为提高海上油气工程能量供应的稳定性,该文提出建立海上微能系统,通过协调海上伴生气存储与电能存储,并耦合海上油气平台余热梯级利用单元,以改善海上油气平台能源利用形式单一、能效低的问题。该文建立海上电-气联合储能模型,并考虑生产工艺系统不确定性对海上微能系统的影响,基于双重不确定性理论构建海上微能系统模糊随机规划模型,利用模糊随机-NSGAⅡ算法对其求解。最后,通过渤海某海上油气平台为实例,验证该文所提模型与方法的可行性与有效性。

Offshore oil and gas engineering is an energy-intensive system, which is mainly composed of two parts: the energy supply system and the production process system. To improve the stability of the energy supply of the system, this paper proposed a micro-energy system for offshore platforms, by coordinating the associated gas storage and power storage of offshore, and coupling the waste heat cascade utilization unit of the offshore oil and gas platform was used to improve the energy utilization form and energy efficiency of the offshore oil and gas platform. This paper established an electricity and associated gas combined energy storage model, and considers the influence of production process system uncertainty on the offshore platform micro-energy system. At the same time, based on the dual uncertainty theory, the fuzzy random programming model of the offshore platform micro-energy system was constructed. The fuzzy random NSGAII algorithm was proposed to solve it. Finally, an example of an offshore oil and gas platform in Bohai was taken as an example to verify the feasibility and effectiveness of the proposed model and method.
