Abstract

Integrated energy system (IES) can improve energy efficiency and optimize energy structure. Due to the similarity and coupling between electric power system and gas network, Gas-electricity integrated energy systems (GEIES) has always been the key research direction of integrated energy system. The optimization of electric power system and gas network is usually independent, the benefits of coordinative optimization are unclear. In this paper, an GEIES model is presented, which is optimized with the goal of maximum revenue under reasonable constraints. The case study shows that the coordinative optimization of GEIES can effectively improve the revenue. Coordinative optimization can increase the earning of electric power system and gas network by about 5% in the model.

气电一体化能源系统的协调优化运行
综合能源系统可以提高能源效率,优化能源结构。由于电力系统与燃气网络的相似性和耦合性,气电集成能源系统一直是集成能源系统的重点研究方向。电力系统和燃气网络的优化通常是独立的,协同优化的效益不明确。本文提出了在合理约束下以收益最大化为目标进行优化的GEIES模型。实例研究表明,GEIES的协调优化可以有效地提高收益。在模型中,协调优化可使电力系统和燃气网络的收益增加约5%。
